Sensory Processing Measure

The SPM is a validated caregiver/teacher-rated tool assessing sensory processing across 8 domains (Vision, Hearing, Touch, Proprioception, Vestibular, Praxis, Social Participation) in children and adolescents. T-score ≥70 indicates definite dysfunction. Miller Kuhaneck et al. (2007).

What is the Sensory Processing Measure?

The Sensory Processing Measure (SPM) is a standardized, norm-referenced caregiver and teacher rating scale developed by Miller Kuhaneck, Henry, and Glennon (2007) to assess sensory processing abilities and related social participation in children ages 5–12. The companion SPM-P (Preschool) covers ages 2–5, and the SPM-2 (2019 revision, WPS) extends the assessment across the lifespan from age 5 through adulthood.

The SPM is designed to be completed by both caregivers/parents (Home Form) and teachers (Main Classroom Form) to capture sensory processing differences across environments. It assesses how the brain interprets and organizes sensory information from the environment and from the body, identifying patterns consistent with sensory over-responsivity, under-responsivity, and sensory seeking.

Scores are converted to age-normed T-scores (mean=50, SD=10). T-scores of 59–69 indicate some problems with sensory processing; T-scores ≥70 indicate definite dysfunction requiring further evaluation and intervention planning. The SPM is widely used by occupational therapists, school psychologists, and developmental pediatricians as part of autism, ADHD, and sensory integration evaluations.

SPM Eight Scales

The SPM measures sensory processing and related functions across eight scales. Each scale produces an independent T-score plus an overall Total Sensory Systems score.

Sensory Patterns & What They Mean

The SPM identifies three response patterns that can co-exist within the same individual, even within the same sensory system.
