• BASS

The BASS is a comprehensive assessment was developed to evaluate individuals who exhibit behaviors associated with the six areas of sexuality; Personal Skills, Relationships and Boundaries, Society and Culture, Sexual Behavior, Internet Awareness, and Sexual Health. The identified population for this assessment include those diagnosed with an Intellectual Disability (ID), Autism and individuals with a dual diagnosis of ID and mental health conditions. 


The BASS assessment results in the implementation of a Skill Development and Behavior Support Plan to enhance the knowledge associated with sexuality, and in turn, reduce the frequency of undesired sexual behaviors.
