Infant/Toddler Sensory Profile

The Infant/Toddler Sensory Profile was a developed to evaluate sensory processing patterns in the very young. The results provide you with the understanding of how sensory processing affects the child’s daily functioning performance.

Features & Benefits

  • Provides a standard method for measuring an infant’s sensory processing abilities.
  • Helps therapist, early childhood teachers, and parents profile the effect of sensory processing on functional performance in the daily life of the infant.
  • Caregivers complete a judgment-based questionnaire, available in English or Spanish, reporting the frequency with which infants respond to various sensory experiences (Almost Always, Frequently, Occasionally, Seldom, or Almost Never.)
  • Provides validated and reliable scores as well as interpretation of results and case studies for your review.

Areas of Assessment


Examine patterns in children from birth to 36 months who are at risk or have specific disabilities related to sensory processing abilities. Caregivers complete a judgment-based questionnaire in 15 minutes, available in either English or Spanish, reporting the frequency (Almost Always, Frequently, Occasionally, Seldom, or Almost Never) with which infants respond to various sensory experiences.


Standardized with 589 cases (100 per age range), the Infant/Toddler Sensory Profile™ provides validated and reliable scores, as well as interpretation of results and case studies for your review.


The Infant/Toddler Sensory Profile consists of 36 items for children birth to 6 months and 48 items for children 7 to 36 months. The caregiver questionnaire contains items divided into sensory systems. For children birth to 6 months, there are four quadrant scores and one combined quadrant score; for children 7 to 36 months, there are five sensory processing section scores, four quadrant scores, and one combined quadrant score available.

The quadrant scores reflect the child’s responsiveness to sensory experiences, and are based on Dunn’s Model of Sensory Processing. Sensation Seeking and Low Registration indicate different high threshold responses, while Sensory Sensitivity and Sensation Avoiding reflect different low threshold responses. Since the low threshold items are particularly relevant with some disability groups, we also provide a combined quadrant score (Low Threshold) that is the combination of Sensory Sensitivity and Sensation Avoiding quadrant scores.

The Sensory Processing scores for children 7 to 36 months indicate the child’s responses to the basic sensory systems. Although there are six sensory processing systems addressed in the questionnaire (i.e., General Processing, Auditory Processing, Visual Processing, Tactile Processing, Vestibular Processing, and Oral Sensory Processing), only five sensory processing systems for children 7 to 36 months have scores: Auditory Processing, Visual Processing, Tactile Processing, Vestibular Processing and Oral Sensory Processing.


Certain patterns of performance on the Infant/Toddler Sensory Profile are indicative of difficulties with sensory processing and performance. In these cases, the team serving the child follows up on the relationship between sensory processing and performance difficulties. Occupational therapists have expertise in sensory processing as part of their professional preparation. Other professionals can acquire this expertise through post-professional education.

Reference Materials

Discover how a parent’s sensory ability can impact a child with Sensory Difficulties

Evaluate parents of a child or infant with sensory processing challenges with Adolescent/Adult Sensory Profile.

By profiling the parents for their sensory processing responses, you will gain valuable insights into the child’s interactions and help to build more family-centered intervention strategies.
