Our Rationale for the ASI Certificate Program

ASI is a well-established and growing area of therapeutic practice with applications in various settings including the home, school, and community. Originally shown to be effective with children with learning and behavior difficulties, this intervention has more recently 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. Although more research is needed in all areas, both research findings and clinical reports now show that this framework is effective and meaningful for many individuals and their families.

Originated in 2016, the ASI Certificate Program was developed to continue the legacy of excellence in education, research and practice in the body of knowledge originated by Dr. A. Jean Ayres and continued by researchers, practitioners, and educators. This education program is produced according to the guidelines of the International Council for Education in Ayres Sensory Integration(R) and aligned with the Ayres 2020 Vision promoting excellence in scholarship, assessment, and education in ASI. 

CLASI offers educational programs in more than a dozen countries around the world.  With many decades of experience in continuing education in ASI, the leaders at CLASI have developed the CASI with an emphasis on optimal learning methods for the various types of content.  The result is a hybrid program which provides self-paced, online learning of content that may require detailed study and review with onsite learning for hands-on concepts that are enhanced through mentored experiences and feedback.  Through this program we hope to establish a cost-effective, accessible educational program through which therapists gain a solid, practical, evidence-based, and effective foundation for using sensory integration theory and practice within their profession toward best practice.  

The administration of the courses is the responsibility of Susanne Smith Roley and Zoe Mailloux, board members of CLASI. They represent first-generation students of Dr. A. Jean Ayres, 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.
