Reference Tool — Not an Assessment

Sensory Processing & Sensory Modulation

Reference Guide — Australian education and behaviour context, 2026. Sensory profiles, differential diagnosis, behaviour translation, assessment and school response.

Important — how to use this tool.

This handbook treats sensory differences as observable functional phenomena, not as a shortcut diagnosis. "Sensory Processing Disorder" is not a standalone DSM-5-TR diagnosis. Sensory hyperreactivity, hyporeactivity and sensory interests are recognised within autism criteria, and sensory difficulties also occur across ADHD, anxiety, DCD, FASD, trauma, intellectual disability and other conditions. A sensory hypothesis should explain a repeatable relation between input, context and behaviour — "he is sensory" explains almost nothing.

Start here — key terms

Term	Practical meaning
Sensory processing	Broad description of how sensory information is detected, filtered, interpreted and used to guide action.
Sensory modulation	Regulation of the intensity and behavioural response to sensory input across context and arousal state.
Hyperreactivity	A response that is unusually intense, rapid or difficult to recover from for a particular input/context.
Hyporeactivity	Reduced or delayed noticing/responding to sensory input.
Sensory seeking	Actively creating or obtaining sensory input; may support alertness, regulation, predictability, enjoyment or information.
Sensory Processing Disorder	A label used in some clinical/OT frameworks, but not recognised as a standalone DSM-5-TR diagnosis; differential assessment remains essential.

Auditory

Sound intensity, frequency, pattern and location.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Auditory processing concerns sound intensity, frequency, pattern and location. School examples: chairs scraping, bells, assemblies, multiple voices.

SWhat it looks like at school

Situation	Possible problem	Useful adjustment
Teacher talking over class noise	Competing speech makes the target signal hard to separate.	Reduce background talk; gain attention first; add visual/written information.
Bell / hand dryer / alarm	Sudden high-intensity sound triggers distress.	Warn where possible; provide distance/ear protection option; plan transition.
Assembly / canteen	Sustained unpredictable multi-source noise creates cumulative load.	Alternative seating/location, planned breaks, quieter access.

Important distinction. Auditory sensory sensitivity is not the same as hearing loss or Auditory Processing Disorder. Refer when hearing/language processing is in question.

✓What helps

Reduce competing speech/noise, pre-warn predictable loud events, consider agreed hearing protection/quiet location, provide written/visual information.

Visual

Light, movement, clutter, contrast and detail.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Visual processing concerns light, movement, clutter, contrast and detail. School examples: fluorescent lights, busy walls, screens, crowded rooms.

SWhat it looks like at school

Load	Potential effect	Adjustment
Fluorescent/bright lighting	Glare, discomfort, headache, reduced concentration.	Natural/dimmer lighting where feasible; seating choice; consider medical causes.
Busy walls / open shelving	Irrelevant visual information competes for attention.	Reduce clutter around work area; clear visual hierarchy.
Movement in peripheral vision	Frequent orienting/distractibility.	Seat away from high-traffic areas if chosen/useful.
Dense worksheets/screens	Visual search and discrimination demands compound cognitive load.	Spacing, chunking, masking, fewer items per page.

✓What helps

Simplify workspace/materials, reduce irrelevant display, chunk information, alter seating/lighting where feasible.

Tactile

Touch, pressure, temperature and texture at the skin.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Tactile processing concerns touch, pressure, temperature and texture at the skin. School examples: uniforms, glue, crowding, accidental touch.

SWhat it looks like at school

Trigger	Possible response	School implication
Unexpected light touch	Flinch, strike out, move away, anger.	Avoid unnecessary touch; approach visibly; warn before assistance.
Crowding / queues	Repeated accidental contact becomes intolerable.	Adjust position, entry/exit timing or personal space.
Messy materials	Avoidance of glue, paint, food or wet textures.	Offer tools/gloves/alternative method when sensory contact is not the learning goal.
Firm pressure	May be preferred by some people, disliked by others.	Never assume deep pressure is universally calming or use it without consent/safety consideration.

✓What helps

Change queue/seat/entry position, preserve personal space, avoid surprise touch.

Taste / Smell

Flavour, odour and chemical cues, including feeding-related sensory issues.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Taste/smell processing concerns flavour, odour and chemical cues. School examples: lunch rooms, perfumes, cleaning products, food.

SWhat it looks like at school

Area	What may happen	Do not reduce it to...
Smell	Perfume, food, toilets or cleaning products can dominate attention or trigger nausea.	"Being fussy".
Taste/texture	Narrow food range, gagging or strong texture rules may affect eating.	A behaviour-management battle.
Feeding	Sensory features may contribute, but feeding problems can also involve oral-motor, swallowing, gastrointestinal, anxiety or ARFID factors.	A sensory-only explanation without assessment.

✓What helps

Avoid coercive exposure; protect nutrition/safety; involve family and appropriate health professionals when intake is restricted. Do not assume "they will eat when hungry".

Vestibular

Head movement, gravity, balance and acceleration.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Vestibular processing concerns head movement, gravity, balance and acceleration. School examples: swings, stairs, spinning, rapid movement.

SWhat it looks like at school

Pattern	May look like
Movement seeking	Spinning, rocking, hanging, running, jumping, constant chair movement.
Movement sensitivity	Fear/avoidance of swings, climbing, stairs, escalators or feet leaving the ground.
Postural/balance difficulty	Cautious movement, fatigue or avoidance; consider motor/vestibular assessment and DCD.

Safety. High movement seeking can create injury risk. Replace unsafe access with safe opportunities rather than assuming punishment will remove the need/drive.

✓What helps

Build legitimate movement access into work rather than waiting until movement becomes rule-breaking.

Proprioceptive

Joint/muscle feedback about force and body position.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Proprioceptive processing concerns joint/muscle feedback about force and body position. School examples: pushing, carrying, crashing, handwriting pressure.

SWhat it looks like at school

Presentation	Possible interpretation
Presses extremely hard with pencil	Force grading may be inefficient; may also be habit, motor difficulty or anxiety.
Crashes into furniture / peers	May seek high-force body feedback; also consider impulsivity, vision, DCD and social awareness.
Likes carrying/pushing/heavy work	Strong muscle/joint feedback may be regulating or satisfying.
Uses too much force socially	Not evidence by itself of aggression intent. Assess whether the student perceived/judged force accurately.

✓What helps

Build legitimate movement/heavy-work access into work; see the sensory tools topic for evidence on weighted items and deep pressure.

Interoceptive

Internal body-state signals.

Reference tool — informs practice, does not diagnose or label.

iWhat it is

Interoceptive processing concerns internal body-state signals. School examples: hunger, thirst, bladder, pain, heart rate, temperature.

SWhat it looks like at school

Internal cue	Functional issue
Hunger / thirst	May not notice until extreme; sudden irritability can follow.
Bladder / bowel	May delay toileting or notice urgency late.
Temperature / fatigue	May need external prompts or routines to respond before discomfort becomes severe.
Emotion-related body cues	Difficulty noticing heart rate, tension or nausea can make escalation feel "sudden".

Series note: interoception and alexithymia are covered in greater depth in Reference Guide #8. Here the focus is their overlap with sensory modulation.

Basics & Terminology

Sensory processing and modulation in one page; terminology; from sensation to functional response.

Reference tool — informs practice, does not diagnose or label.

iSensory processing and modulation in one page

Question	Practical answer
Are sensory differences real?	Yes. Differences in sensory responsivity and sensory-related behaviour are well documented and can substantially affect participation, learning, comfort and regulation.
Is "Sensory Processing Disorder" a formal DSM diagnosis?	No. DSM-5-TR does not recognise SPD as a discrete diagnosis. AAP guidance has cautioned against using it as a standalone diagnosis and recommends evaluating other developmental/behavioural conditions.
Does sensory behaviour automatically mean autism?	No. Sensory differences occur in autism but also ADHD, anxiety, DCD, FASD, trauma and other conditions, and sometimes without a single explanatory diagnosis.
What should schools care about?	Which input is occurring, what the student does, what function the response serves, how the environment changes the response and what adjustment improves participation.
What is the safest starting intervention?	Reduce unnecessary sensory barriers, offer predictable options, teach communication/self-advocacy and test supports against observable participation outcomes rather than assuming a sensory explanation.

Core rule. A sensory hypothesis should explain a repeatable relation between input, context and behaviour. "He is sensory" explains almost nothing.

iTerminology: difference, difficulty, symptom and disorder

Term	Use it when...	Do not assume...
Sensory difference	A person notices, seeks or responds to input differently from peers.	That difference is pathological or requires treatment.
Sensory difficulty	The sensory pattern interferes with comfort, access, participation or daily functioning.	That the child lacks coping skills or is deliberately difficult.
Sensory symptom	The sensory feature is part of a recognised condition or clinical presentation.	That sensory symptoms identify the diagnosis by themselves.
Sensory disorder	Use cautiously and according to the clinician/framework involved.	That "SPD" has independent DSM-5-TR diagnostic status.

iFrom sensation to functional response

Stage	Example: school bell
Detection	Auditory receptors register sound.
Filtering / salience	The nervous system decides how much attention the sound deserves among competing input.
Interpretation	"That is the bell; class is changing" versus "That sound is painfully intense / threatening / impossible to ignore."
Regulation	Arousal rises, stays stable or drops depending on the person and context.
Action	Move class, cover ears, flee, yell, freeze, seek adult support or continue unaffected.

Response Patterns — Hyperreactivity, Hyporeactivity & Sensory Seeking

The three core response types across any sensory system.

Reference tool — informs practice, does not diagnose or label.

iHyperreactivity / over-responsivity

May look like	Possible sensory mechanism	Important alternative
Hands over ears / leaving	Sound is experienced as highly salient, painful or overwhelming.	Anxiety, migraine, hearing condition, learned escape.
Refuses clothing/materials	Tactile input is unusually aversive.	Skin condition, pain, preference, rigidity.
Explodes in crowded room	Multiple inputs exceed tolerable load.	Social threat, demand load, trauma, ADHD overload.
Avoids bright room/screen	Visual intensity or flicker is difficult.	Headache, visual problem, fatigue.

Key point. Hyperreactivity is not "being dramatic". But intensity alone does not tell you why the stimulus is difficult. Test context and alternatives.

iHyporeactivity / under-responsivity

Presentation	Possible interpretation
Slow to notice name being called	The signal may not win competition for attention; do not assume deliberate ignoring.
Reduced response to pain/cold/heat	May indicate reduced noticing or expression; still investigate injury and medical risk.
Does not notice dirty hands/face/clothing	Reduced salience of tactile/interoceptive cues may contribute.
Seems "switched off" in busy spaces	Could reflect sensory under-registration, shutdown, attention, fatigue or dissociation.

iSensory seeking

Behaviour	What the input may provide
Rocking, pacing, bouncing	Rhythmic vestibular/proprioceptive input; alerting, regulating or predictable feedback.
Chewing objects/clothes	Oral/tactile/proprioceptive input; may also reflect anxiety or habit.
Crashing, rough play, pushing	High-force proprioceptive input; may coexist with impulsivity or social-skill problems.
Making noises / repeating sounds	Auditory feedback, predictability, enjoyment, arousal regulation or communication.
Touching everything	Tactile exploration/seeking; also consider impulsivity and curiosity.

Discrimination & Sensory-Motor Performance

Sensory discrimination; praxis, posture and sensory-motor performance.

Reference tool — informs practice, does not diagnose or label.

iSensory discrimination

Difference	Possible functional effect
Difficulty locating or distinguishing touch	May use vision to compensate; dressing or object handling may be slow.
Difficulty judging force/pressure	Breaks pencils, presses hard, bumps people or uses too much/too little force.
Difficulty distinguishing sounds in noise	May misunderstand speech even when hearing acuity is normal; language/hearing assessment may be needed.
Body-position discrimination difficulty	Movement can look clumsy or inefficient; consider DCD and motor assessment.

iPraxis, posture and sensory-motor performance

Concept	What it means	Behavioural trap
Praxis	Generating, planning and executing unfamiliar purposeful movement.	"He refuses PE" when novel motor tasks are humiliating/difficult.
Postural control	Maintaining stable body position against gravity while acting.	"Lazy/slouching" when endurance/control is poor.
Bilateral coordination	Using both sides of the body together efficiently.	Avoidance of cutting, sport, dressing or equipment.

Important differential. DCD is a recognised neurodevelopmental diagnosis and should be considered when motor performance is the core problem. Do not rename motor disability as "sensory".

Modulation, Arousal & Mixed/Context-Dependent Profiles

Why sensory responses shift with arousal state and context, and why one label rarely fits.

Reference tool — informs practice, does not diagnose or label.

iModulation, arousal and regulation

Arousal state	What sensory input can do
Too high	Additional noise, touch or visual movement may push the student further toward escape/aggression/shutdown. Predictability and reducing input may help.
Too low	Movement, novelty, rhythm or stronger proprioceptive input may increase alertness for some students.
Just right	The student can notice relevant input without being dominated by it and can participate.

Caution. "Calming" and "alerting" sensory recipes are not universal. The same input can regulate one student and dysregulate another, or work differently on another day.

iProfiles can be mixed and context dependent

Example	Why a single label fails
Seeks loud music but hates hand dryers	Response differs by predictability, control, frequency, meaning and acoustic properties.
Enjoys hugs from chosen people but reacts to accidental touch	Control, expectation and relationship change the tactile event.
Seeks spinning at home but avoids PE movement	Vestibular input is not identical across speed, posture, unpredictability and social demand.
Tolerates noise in gaming but not classroom chatter	Chosen, meaningful input is different from uncontrollable competing speech during cognitive work.

Cumulative Sensory Load & Distress vs Preference

Why the "final" trigger is rarely the whole story, and how to tell distress from ordinary dislike.

Reference tool — informs practice, does not diagnose or label.

iCumulative sensory load

Load source	Contribution
Noise + movement + crowding	Several moderate inputs can combine into an intolerable total load.
Academic demand	Hard thinking reduces spare regulatory capacity for irrelevant sensory input.
Fatigue / hunger / heat / pain	Internal state can lower tolerance for external input.
Uncertainty and social threat	Arousal can amplify sensory salience; the student may tolerate the same room on a predictable day and not during conflict.

Implication. Track the whole preceding period. The "tiny" final sound/touch may be the last input, not the whole cause.

iSensory distress versus preference or dislike

Question	More consistent with ordinary dislike	More concerning functional sensory difficulty
Intensity	"I hate that noise."	Pain/distress, panic-like response, immediate escape, loss of functioning.
Flexibility	Can usually tolerate briefly when needed.	Tolerance remains very limited despite motivation/reward.
Recovery	Annoyed, then continues.	Long recovery or escalating load after exposure.
Participation	Preference does not substantially restrict access.	Avoids environments, tasks, hygiene, food, clothing or social participation.

Medical Red Flags

Do not miss pain, illness or sensory impairment; other medical and neurological differentials.

Reference tool — informs practice, does not diagnose or label.

!Do not miss pain, illness or sensory impairment

Presentation	Rule out / consider
Sudden sound sensitivity	Ear infection, hearing change, migraine, headache, medication effects.
Sudden touch avoidance	Skin injury, dermatitis, neuropathic pain, musculoskeletal injury.
Food texture refusal / gagging	Oral-motor/swallowing problem, reflux, allergy, dental pain, ARFID, gastrointestinal issues.
Light sensitivity	Migraine, eye disorder, concussion, medication effects.
Reduced pain response	Expression/communication differences do not make injury safe; assess objectively.

Red flag. A new or rapidly worsening "sensory" behaviour is not automatically a sensory-processing issue. New symptoms deserve medical/clinical consideration.

iOther medical and neurological differentials

Sensory complaint	Consider
Sound/light sensitivity	Migraine, concussion, hearing/vision issues, medication effects.
Tingling/burning/touch pain	Neuropathy, injury, dermatological conditions.
Dizziness/motion intolerance	Vestibular disorder, vision, migraine, autonomic issues.
Unusual smells/tastes or episodic sensory experiences	Medical/neurological causes may require assessment.
Restricted eating	ARFID, gastrointestinal conditions, oral-motor/swallowing problems, allergy, dental pain.

Sensory Differences and Autism

What is established and what is not, per DSM-5-TR and Australian guidance.

Reference tool — informs practice, does not diagnose or label.

iWhat is established / what is not established

What is established	What is not established
DSM-5-TR autism criteria include hyper- or hyporeactivity to sensory input or unusual sensory interests within restricted/repetitive behaviour criteria.	Sensory symptoms alone do not diagnose autism. Social-communication criteria and the broader developmental pattern are still required.
Sensory differences are common and can substantially affect autistic students at school.	Every autistic person does not have the same profile or need the same sensory supports.
Australian Autism CRC guidance emphasises meeting sensory needs across activities/settings and adapting environments.	The goal should not automatically be to suppress harmless sensory seeking/avoiding to make behaviour look "normal".

Differential Diagnosis — ADHD, Anxiety, DCD & Trauma

Four commonly confused or co-occurring presentations.

Reference tool — informs practice, does not diagnose or label.

iSensory presentation versus ADHD

Looks sensory	Could be ADHD-related
Constant movement	Motor hyperactivity, novelty seeking or difficulty maintaining alertness.
Touches everything	Impulsivity and poor inhibition.
Does not respond to name	Attention is captured elsewhere rather than under-registration of sound.
Distracted by every noise	Difficulty suppressing competing stimuli can mimic auditory sensory sensitivity.

Best clue: ask whether the response is specifically tied to sensory properties and whether changing that input reliably changes participation.

iSensory presentation versus anxiety

Pattern	Sensory hypothesis	Anxiety hypothesis
Avoids noisy hall	Sound itself is aversive/overwhelming.	Hall predicts crowds, judgement, conflict or uncertainty.
Cannot tolerate touch	Tactile input is intensely uncomfortable.	Touch signals threat/loss of control.
Somatic distress	Sensory input drives physiological overload.	Anxiety amplifies body sensations and vigilance.
Reality	Both can coexist and amplify each other. Do not force a false either/or.

iSensory presentation versus DCD

Presentation	Why DCD matters
Avoids sport / playground	Motor coordination and repeated failure may be the primary issue rather than sensory avoidance.
Crashes / bumps into things	Could reflect coordination, timing, spatial judgement or balance difficulty.
Slow dressing / tool use	Motor planning and coordination may be more explanatory than tactile processing.

Key point: DCD is a recognised neurodevelopmental disorder. When motor skill acquisition/performance is markedly impaired, do not stop at a sensory label.

iTrauma, hypervigilance and sensory cues

Observation	Possible sensory mechanism	Possible trauma mechanism
Startles at doors/slams	Sound intensity is aversive.	Sudden sound has acquired threat meaning.
Rejects touch	Tactile defensiveness.	Touch is associated with threat or loss of control.
Scans room / cannot ignore movement	Visual sensitivity/distractibility.	Hypervigilance for potential danger.

Important. Sensory accommodation can still help regardless of cause, but trauma-specific symptoms require trauma assessment/treatment rather than a sensory-only plan.

FASD, and Language/Intellectual/Adaptive-Functioning Effects

How cognitive and adaptive profile shapes — and can imitate — sensory presentation.

Reference tool — informs practice, does not diagnose or label.

iSensory presentation in FASD

Overlap	Why interpretation is difficult
Overload in busy spaces	May involve sensory sensitivity plus attention/executive-function limitations and weak filtering.
High movement/roughness	Could reflect sensory seeking, impulsivity, motor regulation or weak force judgement.
Late response to body cues	May overlap with interoception, memory, adaptive functioning and self-monitoring difficulties.

Support implication: use the FASD profile — simplify environment, reduce competing demands, externalise regulation and do not assume sensory strategies alone solve neurocognitive disability.

iLanguage, intellectual and adaptive-functioning effects

Issue	How it can imitate or worsen sensory behaviour
Limited receptive language	Student cannot understand explanations during overload and may appear increasingly "sensory" as demands continue.
Weak self-report	May lack vocabulary to describe pain, sound quality, body sensations or what needs to change.
Adaptive-functioning weakness	May not independently plan headphones, breaks, hydration or clothing changes even when they know these help.
Intellectual disability	Response may reflect comprehension, communication and coping demands as much as the sensory stimulus itself.

Behaviour-Reading — Refusal/Aggression, Stimming & Shutdown

When sensory distress looks like refusal or aggression; stimming and movement; shutdown and withdrawal.

Reference tool — informs practice, does not diagnose or label.

iWhen sensory distress looks like refusal or aggression

Adult label	Possible hidden sequence	Better question
"Refusing assembly"	Anticipates unbearable noise/crowding → avoids entry.	What changes if noise, seating, duration or exit access changes?
"Aggressive when touched"	Unexpected touch → rapid defensive response → adult interprets intent after the fact.	Does aggression occur specifically after proximity/touch and reduce when space is protected?
"Won't wear uniform"	Texture/temperature/pressure is persistently aversive.	Can an equivalent uniform adjustment preserve the actual school requirement?
"Runs out for no reason"	Cumulative load passes threshold → escape.	What sensory/social/demand variables rose in the previous 10–30 minutes?

iStimming, movement and "attention seeking"

Behaviour	Possible functions
Rocking / hand movements	Rhythm, predictability, sensory feedback, emotional regulation, enjoyment.
Pacing / standing	Movement may support alertness, thought organisation or regulation.
Vocal repetition	Auditory feedback, self-regulation, communication or pleasure.

Adult response. If safe and not materially blocking participation, suppression may create more cost than benefit. If it disrupts access, look for function-compatible alternatives rather than simply stopping it. A repetitive sensory behaviour can be socially noticeable without being harmful — "looks odd" is not a sufficient intervention target.

iShutdown, withdrawal and apparent non-response

Observed	Possible explanations
Head down / hood up / eyes closed	Reducing visual and social input; fatigue; shame; migraine; avoidance.
Stops talking	Overload may reduce language access; also consider selective mutism, anxiety, DLD, dissociation.
Does not answer	May need longer processing time or reduced competing input; could also be deliberate non-response.
Moves to isolated space	May be adaptive self-regulation rather than "escaping responsibility". Plan return conditions rather than blocking all escape.

School Sensory Audit & FBA Sensory Variables

Change the environment first, and how to build sensory variables into a functional behaviour assessment.

Reference tool — informs practice, does not diagnose or label.

iSchool sensory audit: change the environment first

Audit area	Questions
Sound	Where are bells, fans, scraping chairs, reverberation, shouting, PA speakers and competing speech strongest?
Visual	Is the workspace visually dense? Flicker/glare? Constant pedestrian movement? Too much information displayed at once?
Touch / crowding	Where are queues, narrow doorways, shared mats, packed seating and accidental contact unavoidable?
Smell / temperature	Cleaning products, food areas, toilets, heat, poor ventilation?
Movement access	Can the student move without turning every movement need into a disciplinary issue?
Control / predictability	Can the student anticipate intense events and access an agreed adjustment before reaching crisis?

Australian context: Autism CRC's 2026 National Guidance for inclusive education explicitly includes the physical environment as a best-practice domain, and its school resources include classroom sensory audits.

iFunctional behaviour assessment and sensory variables

FBA element	Sensory-specific question
Antecedent	What exact sensory input occurred? Intensity? duration? predictability? control? cumulative load?
Behaviour	What did the student do that is observable, rather than "became sensory"?
Consequence	Did the behaviour remove/reduce input, create preferred input, produce distance, gain regulation support or change demands?
Setting events	Sleep, pain, heat, hunger, medication, conflict, previous noise/crowding, cognitive load.
Test	Does changing the hypothesised sensory variable reliably change the behaviour/participation?

Assessment & Sensory Diets

What assessment tools can and cannot tell you, and how to tell a genuine sensory diet from ritualised guesswork.

Reference tool — informs practice, does not diagnose or label.

iAssessment: what tools can and cannot tell you

Assessment source	Useful for	Limit
Interview / student report	Identifying lived sensory experience, preferences and triggers.	Requires communication access; self-report can vary with context.
Direct observation	Linking actual environments to behaviour/participation.	One setting may not represent the full profile.
Sensory Profile / Short Sensory Profile	Structured caregiver/teacher ratings of sensory-related behaviours.	Questionnaire pattern is not an independent medical diagnosis and captures behaviour influenced by attention/motor factors.
Sensory Processing Measure (SPM)	Cross-setting sensory, praxis and participation ratings.	Still requires clinical interpretation and differential assessment.
OT assessment	Functional analysis of occupations, environment, motor/sensory factors and supports.	Quality depends on question, methods and whether outcomes are participation-based.

iSensory diets: useful plan or ritualised guesswork?

Potentially useful	Poor practice
A planned set of supports tied to specific functional goals, individual response and review data.	Generic "heavy work every 2 hours" because a checklist says so.
Student has choice and learns which strategies help in which contexts.	Adult imposes sensory activities regardless of student response.
The environment is adjusted alongside individual strategies.	All responsibility sits with the child to tolerate an inaccessible environment.
Effect is evaluated: participation, distress, task access, recovery time.	Success is assumed because the activity looks therapeutic.

Sensory Tools & Interventions

Weighted items, deep pressure, brushing; Ayres Sensory Integration; and what the intervention evidence currently says.

Reference tool — informs practice, does not diagnose or label.

iWeighted items, deep pressure, brushing and other sensory tools

Tool / approach	Evidence / practice caution
Weighted vests / blankets	Do not assume they improve attention or behaviour broadly. Individual comfort and safety matter; evidence for many sensory-based modalities remains mixed/limited.
Deep pressure	Some individuals report it as calming; others dislike it. Consent, preference and safe application matter.
Brushing protocols	Should not be treated as routine classroom behaviour treatment; evidence is limited and specialised protocols require appropriate professional oversight.
Chew/fidget/movement tools	Can be practical accommodations when they improve access without causing harm or major disruption. Evaluate function rather than the object's popularity.
Ear protection	Can provide immediate access in high-noise contexts. Balance useful protection with the student's actual goals and clinical advice where hearing concerns exist.

iAyres Sensory Integration (ASI)

ASI is...	ASI is not...
A manualised/fidelity-defined occupational therapy approach using individually tailored sensory-motor play and "just-right" challenge.	Any activity involving swings, brushing, weighted items or a "sensory room".
Delivered by appropriately trained occupational therapy practitioners in a specialised context.	A generic teacher-led sensory break.
Evaluated increasingly using participation and individual-goal outcomes.	Established as a universal treatment for behaviour of concern or autism itself.

iWhat the intervention evidence currently says

Evidence point	Current interpretation
ASI RCT review (2025)	A systematic review of nine RCTs (344 children) reported strong evidence for individual goal attainment in autistic children, but moderate evidence of no benefit for behaviours of concern such as noncompliance/irritability.
OT ASI systematic review (2025/26 literature)	A review of 2015–2024 studies reported strong evidence for individual goal attainment/occupational performance and moderate evidence for some daily living/social/play outcomes.
Broader sensory-based modalities	Evidence varies by intervention. Older AAP guidance and autism reviews caution that many commonly used modalities have limited or inconsistent evidence.
Best practice implication	Choose a specific target, use the least intrusive support, measure functional outcomes and stop/modify approaches that do not help.

Do not overclaim. Evidence that an intervention helps selected occupational goals is not evidence that it "fixes sensory processing", treats autism, or reduces all behaviour of concern.

Practical School Supports, Translation Guide & Evidence Base

High-utility responses by problem area, a one-page translation guide, and the reference list.

Reference tool — informs practice, does not diagnose or label.

✓Practical school supports and adult responses

Problem	High-utility response
Noise overload	Reduce competing speech/noise, pre-warn predictable loud events, consider agreed hearing protection/quiet location, provide written/visual information.
Crowding/touch	Change queue/seat/entry position, preserve personal space, avoid surprise touch.
Visual overload	Simplify workspace/materials, reduce irrelevant display, chunk information, alter seating/lighting where feasible.
Movement need	Build legitimate movement access into work rather than waiting until movement becomes rule-breaking.
Sensory escape during learning	Separate the sensory barrier from the academic expectation: modify the environment while preserving the actual learning goal.
Escalation	Reduce language and unnecessary input first. Do not add crowding, repeated questions, touch or public confrontation.
Recovery	Allow regulation time, then review specific variables when calm; avoid demanding a detailed sensory explanation during overload.
Planning	Record what reliably helps, what reliably worsens, and when the same strategy fails. Sensory support should be dynamic, not superstition.

Useful formulation. Input + context + current load → sensory experience → regulation/communication/escape response → adult/environment consequence. That sequence is more actionable than "sensory behaviour".

✓One-page school behaviour translation guide (quick reference)

What staff see	Possible sensory / related explanation	What to test
"Ignoring me"	Signal is not salient, competing noise, overload, attention capture.	Gain attention visually, reduce noise, shorten message, check hearing/language.
"Refuses assembly"	Noise/crowding/predictability exceeds tolerance.	Different seat, entry, duration, headphones, exit plan.
"Hits when people come close"	Unexpected tactile/proximity input triggers rapid defensive response.	Increase space, warn before touch, test crowding variables; still teach safety.
"Constantly out of seat"	Movement may support alertness/regulation; ADHD may also contribute.	Planned movement/standing versus forced sitting; compare engagement.
"Chews everything"	Oral sensory seeking/regulation.	Safe chew option and monitor when/why seeking rises.
"Doesn't feel pain"	Reduced response/expression or attention to body cues.	Objectively check injury; do not use apparent tolerance as safety evidence.
"Melts down over nothing"	Final input may be last part of cumulative sensory + demand + fatigue load.	Track previous 30–60 minutes, not just the final trigger.
"Attention seeking" stimming	Behaviour may produce useful sensory feedback independently of adult attention.	Does it occur alone? Does safe access reduce other dysregulation?
"Won't use messy materials"	Tactile aversion or disgust response.	If touch is not the learning outcome, allow tools/alternative method.
"Needs sensory break every lesson"	May be genuine support, learned routine, escape from difficult work, or all three.	Measure return-to-task, distress and whether changing work difficulty alters break requests.

iFor school use — bottom line

Step	What it means
Describe	Name the exact input, behaviour, context and functional impact.
Differentiate	Consider autism, ADHD, DCD, FASD, language/adaptive difficulties, anxiety, trauma, pain and hearing/vision/medical causes.
Adjust	Remove unnecessary environmental barriers and provide choice/communication before trying to "train tolerance".
Measure	Judge supports by participation, distress, independence, safety and recovery — not by whether the intervention looks sensory.
Refer	Use OT, speech pathology, psychology, audiology, medical and other assessment according to the actual question.
