Sensory Processing Differences
Standardised tools for assessing Sensory Processing Differences in early childhood
Early-childhood sensory assessment uses caregiver-report and observation tools — the Sensory Profile 2 (with Infant/Toddler versions), the SPM-Preschool, and the TSFI for infants — triangulated with structured play-based observation. No single tool is diagnostic; interpretation is clinician-led and grounded in functional participation.
The first question in any sensory query is the same: which instruments give us a defensible, reproducible profile in a child this young?
In short
For early childhood, sensory assessment combines caregiver-report questionnaires with structured observation and functional analysis. The most widely used standardised tools are the Sensory Profile 2 (including the Infant and Toddler versions, birth–35 months), the Sensory Processing Measure — Preschool (SPM-P), and the Test of Sensory Functions in Infants (TSFI) for the youngest cohort. These are screened and contextualised — never diagnostic in isolation — against developmental history and direct play-based observation.The science, briefly
Sensory questionnaires map a child's responses across modalities (auditory, tactile, vestibular, proprioceptive, visual, oral) and against quadrant patterns of registration, seeking, sensitivity and avoiding. The Sensory Profile 2 offers age-banded norms and caregiver/teacher forms; the SPM-P adds home and classroom social-participation lenses; the TSFI suits 4–18-month infants where self-report is impossible. Best practice triangulates these with structured observation, the DUNN sensory framework, and functional impact on feeding, sleep, play and self-regulation — consistent with the WHO ICF emphasis on participation rather than isolated impairment. No single tool is sufficient; interpretation must be clinician-led and ecologically grounded.When to escalate
Use standardised tools when sensory responses persistently disrupt daily participation, co-occur with motor or communication concerns, or when caregiver report and observation diverge. Always rule out hearing, vision and pain-driven causes first.The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from a questionnaire alone or an online form. Our occupational therapists pair these standardised instruments with structured observation to build a working profile.

What to watch
Persistent sensory responses that disrupt feeding, sleep, play or self-regulation across settings; divergence between caregiver report and direct observation; co-occurring motor or communication concerns.
Try this at home
Always pair a questionnaire with at least one structured observation in a familiar, low-stress setting — caregiver report and clinician observation together give a far more reliable profile than either alone.

Frequently asked
Is the Sensory Profile 2 suitable for infants?
Yes — the Sensory Profile 2 family includes Infant (birth–6 months) and Toddler (7–35 months) caregiver-report versions, alongside the child and school companion forms, giving age-banded norms across early childhood.
Can a sensory questionnaire alone confirm Sensory Processing Differences?
No. Standardised questionnaires screen and characterise patterns, but they are not diagnostic in isolation. They must be triangulated with structured observation, developmental history and functional impact, under qualified clinician interpretation.
Which tool suits the youngest infants?
The Test of Sensory Functions in Infants (TSFI) is designed for roughly 4–18 months, where self-report is impossible and caregiver-report plus structured observation drive the profile.
