The following core content is essential knowledge for the occupational therapist using the sensory integrative frame of reference in best practice.

Sensory Integration Theory:


  • The original works of Dr. A. Jean Ayres;

  • Sensory integration-related publications and research;

  • Typical and atypical development;

  • Concepts of neuroplasticity, function and dynamic interactions of major neural areas, sensory processing, integration, and perception.


Assessment of Sensory Integration and Praxis:


  • Understanding of the way in which assessments of sensory integration are administered as part of an overall occupational therapy evaluation (see Occupational Therapy Practice Framework, AOTA, 2002).

  • Knowledge of sensory integration theory and tests and measurement necessary to administer and interpret the Sensory Integration and Praxis Tests and related information.

  • Competence in administration of The Sensory Integration and Praxis Tests, a set of rigorously designed standardized tests that are considered the “gold standard” for assessing sensory integration and praxis. The SIPT were developed for assessing children ages 4 years to 8 years 11 months;

  • Skilled assessment of postural control through clinical observations and sensory modulation through parent report.

  • Skilled assessment of sensory modulation and self-regulation through family and teacher report.

  • Skilled observations of typical and atypical behaviors related to sensory integrative processes.

Interpretation of Assessment Data for Intervention Planning


  • Ways to analyze assessment data that includes the SIPT, Clinical Observations, Sensory Histories and Occupational Profile for the development of an intervention plan.

  • Understanding of sensory systems and factor and cluster analysis providing insights into patterns of sensory integrative dysfunction.

  • Knowledge of patterns of sensory integrative dysfunction that may predict strengths and weaknesses in the individual’s ability to function and to guide intervention.

  • Understanding of the implications of sensory integrative dysfunction and its relationship to functionally relevant goals and objectives.

  • Analysis of the relationship of sensory integrative dysfunction and its impact on participation in the family, home and school.


Occupational Therapy Intervention using Sensory Integrative Strategies


  • Knowledge of sensory integration as both a method and philosophy of intervention.

  • Comprehension of the ways in which the sensory integrative frame of reference is used by occupational therapists as part of their overall professional practice.

  • Skill in application of the principles of sensory integration including providing the proper environment, necessary equipment, planning space, timing, and rhythm of the sessions, and making environmental modifications.

  • Appreciation for inclusion, education, and consultation with the family and other significant individuals.
