Frequently Asked Questions

+ What is Ayres Sensory Integration® ?

Ayres Sensory Integration® (ASI) is a well-established and growing area of therapeutic practice with applications in various settings including the home, school, and community. Developed by A. Jean Ayres, PhD, OTR, FAOTA, an occupational therapist, psychologist, and neuroscientist, this framework was originally shown to be effective with children with learning and behavior difficulties and has since emerged as an evidence-based practice for use with children with autism. Applications have been broadly applied with individuals with a variety of disabilities and age- groups. ASI is trademarked to help researchers, therapists, and parents identify the core principles which define ASI and to differentiate this evidence-based intervention from other approaches which may use some aspects of sensory-based activities, but do not meet the criteria for ASI.

+ What is the CLASI-CASI?

The Certificate in Ayres Sensory Integration (CASI), offered through the Collaborative for Leadership in ASI (CLASI), is an advanced training program that was initiated in 2016 to continue the legacy of excellence in education, research, and practice in the body of knowledge which was originated by Dr. A. Jean Ayres and which has been continued by other researchers, practitioners, and educators. This education program is produced according to the guidelines of the International Coalition of Education in Ayres Sensory Integration® and aligned with the Ayres 2020 Vision, promoting excellence in scholarship, assessment, and education in ASI.

+ What is included in the CLASI-CASI program?

The CLASI CASI includes 6 Modules (four online and two onsite) plus supplemental activities, assignments, and webinars, for a total of 180 hours. The modules are designed for therapists as a comprehensive and practical foundation of knowledge and skills in ASI theory, assessment, and intervention. The training builds competencies from research to practice, including administering and interpreting the SIPT and EASI, and results in the CLASI Certificate in Ayres Sensory Integration. A detailed description of the six Modules can be found at

+ Who can enroll in the CLASI-CASI program?

M1 – open to all who wish to learn about ASI theory.
M2, M3, M4, M5 – open to healthcare professionals with at least bachelor level equivalent college/university degrees in occupational therapy, speech pathology, physical therapy, psychology, or medicine.
M6 – is open to occupational therapists (OT), physical therapists (PT), and speech and language pathologists (SLP).

*Participants will receive a certificate of attendance to verify continuing education credit (approved by the American Occupational Therapy Association (AOTA) for each Module. However, the CLASI – CASI Certificate in Ayres Sensory Integration is restricted to occupational therapists, physical therapists, and speech and language pathologists

+ What if I already hold an Ayres Sensory Integration Certificate from another program?

While having multiple certificates is not necessary, qualified therapists who have previously completed an SI Certificate program through an approved program are welcome to register for any of the CLASI CASI modules.

+ How can I compare the CLASI CASI to other certificate or training programs in sensory integration?

While we cannot evaluate or represent other programs, we are happy to describe ours. The CLASI program was developed by Zoe Mailloux, OTD, OTR/L, FAOTA and Susanne Smith Roley, OTD, OTR/L, FAOTA both of whom were students of Dr. A. Jean Ayres. They are committed to following her tradition of excellence and research in practice. Course materials are derived from Ayres’ original publications and subsequent research in basic and applied science related to sensation and the impact on human function. In addition, CLASI instructors are lecturers with in-depth knowledge in the areas of ASI, representing first- and second-generation students of Dr. Ayres. The instructors have national and international experience in presentations of information on ASI and expertise in ASI research, education, and practice.

CLASI is also a founding member of the International Council for Education (ICEASI) in Ayres Sensory Integration®, an organization which aims to provide global standards for education and training in ASI.

+ If I’ve started my Sensory Integration Certification process with another organization, can I switch to CLASI?

Applying hours of training completed from another organization toward the CLASI CASI will be decided on a case-by-case basis. Consideration of the completed training in regard to the ICEASI standards and the length of time since the training was completed will determine whether or not it is possible to apply credit from another program.

+ Are continuing education/professional development units provided through this program training?

Each module will provide 30 hours of training, including the assignments, for a total of 180 hours for the program. CLASI is an approved provider of continuing education units (CEU) by the American Occupational Therapy Association.

+ How long do I have to complete the CLASI-CASI Program?

Once registered, online course content can be accessed for at least one year. It is our hope that these materials will be reviewed to support ongoing learning throughout the process. We recommend that participants complete the whole program, including the onsite modules and assignments, within one year. Since life sometimes gets in the way of plans, the maximum amount of time allowed for completion of the program is five years.

+ Can I take the modules out of order?

We recommend taking the modules in order, but we realize there may be exceptions.

M1 (Ayres Sensory Integration Theory) – These lessons in ASI theory can be completed over time, and review of this information throughout the program is recommended. While it will be helpful to complete M1 prior to M2 & M3, it is not essential. However, it will be very difficult to fully synthesize the information in lessons M4 - M6 if M1 has not been completed.

M2 (Comprehensive Assessment in ASI) – The lessons in ASI assessment must be completed prior to M3 since this module provides essential information for administering and scoring a variety of assessment tools which will be only briefly reviewed and then practiced in M3.

M3 (Hands-on Comprehensive Assessment in ASI) – This onsite ASI hands-on course assessment information must be completed prior to M4. The tests which are learned and practiced will be used to evaluate children with valid and reliable results prior to interpreting those data.

M4 (Clinical Reasoning in ASI) – ASI clinical reasoning is needed prior to M6 because you will need to do the problem identification portion of clinical reasoning prior to the problem solution, which is your intervention.

M5 (Evidence-Based ASI Intervention Including Fidelity to Intervention) – The ASI fidelity measure will be needed prior to completion of the whole certificate program because you will be asked to rate your and others’ intervention sessions.

M6 (Evidence-Based ASI Intervention Hands-on Practice and Review) – ASI hands-on intervention is best completed when you have a firm foundation in theory, assessment, and principles of intervention.

+ Does the CLASI CASI include training in the Sensory Integration and Praxis Tests (SIPT)?

Based on our work with Dr. Ayres, we believe that comprehensive assessment is a cornerstone to appropriate and effective intervention. The Sensory Integration and Praxis Tests (SIPT) are currently the strongest tools available for assessing children who may have sensory integration problems hindering their ability to participate fully in their daily lives. Therefore, the current CLASI CASI includes instruction and practice with the SIPT.

A new set of tests, the Evaluation in Ayres Sensory Integration (EASI), are currently under development with international normative data expected by 2020. The EASI is also introduced and practiced in the program, and it is likely that many participants in the program will feel prepared and inspired to be normative data collectors for the EASI. Other tests which assess aspects of sensory integration functions are also discussed.

Rather than providing a certification in any one set of tests, we strive to enhance an understanding of the core concepts of ASI, including the main areas that must be included in a comprehensive assessment.

+ Therapists have asked about the scope and content of CLASI's postgraduate Certificate in Ayres Sensory Integration® and whether or not we provide "SIPT Certification." Are these the same?

Simply, CLASI's certificate encompasses the broad set of knowledge and skills that support therapy practice using Ayres Sensory Integration(R). The CLASI program emphasizes the importance of comprehensive assessment, which currently involves instruction and mentored practice in the administration and scoring of the Sensory Integration and Praxis Tests (SIPT) and the Sensory Processing Measure (SPM,) as well as emerging tools such as the Evaluation in Ayres Sensory Integration (EASI).

To provide some historical background, "SIPT Certification" was the name for the certificate process originated by the Center for the Study of Sensory Integrative Dysfunction (CSSID), later known as Sensory Integration International (SII), 1976-2006.

From 1998-2016, the USC/WPS program offered the Certificate in Sensory Integration including Administering and Interpreting the SIPT. The language used in this certificate was often referred to as "SIPT Certification" even though it was a certificate program and encompassed more than the SIPT.

Completion of the CLASI CASI program provides therapists the opportunity to obtain the Certificate in Ayres Sensory Integration(R) including administering and interpreting the SIPT and introduction to the Evaluation in Ayres Sensory Integration (EASI). The name of this certificate reflects the evolution of the body of knowledge that is now trademarked, and builds on the use of the SIPT and related assessments to guide evidence-based intervention using the Data-Driven Decision Making Model. The EASI is taught in this series and will continue to be updated as this tool develops.

+ Will I need a SIPT kit to participate in the CLASI CASI?

To receive the final certificate, learners will need to document assessments with two children who have suspected problems in sensory integration. The tests which are required will evolve as the new measures are available. While no specific test kit is required (necessary test kit materials will be made available at the onsite courses as needed), test manuals, test sheets, and scoring are required to practice and complete the required cases. For therapists who do not have their own test sheets or scoring, materials can be purchased at a discount for use in learning the tests. Learners must bring or have access to the following:
