Standardised tools for assessing Sensory Processing Differences in early childhood

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

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from a questionnaire alone or an online form. Our occupational therapists pair these standardised instruments with structured observation to build a working profile.
