During this session, participants will learn how to conduct structured observations of students suspected of having an ASD across settings and how to conduct interviews with students, parents, and other staff members as part of the comprehensive team-based evaluation. Several formalized assessments will be shared during this session that focus on interviewing students including the Autism Diagnostic Interview –Revised (ADI-R) The ADI-R is a comprehensive interview that has proven highly useful for formal diagnosis and educational eligibility as well as treatment and educational planning. An experienced clinical interviewer questions a parent or caregiver who is familiar with the developmental history and current behavior of the individual being evaluated. The Autism Diagnostic Observation Schedule-2 (ADOS-2) , considered a “gold standard” autism assessment instrument, also has interview questions that can be utilized with students who are verbally fluent. Other formal and informal interviews such as the Childhood Autism Rating Scale -2 Caregiver Parent Questionnaire (CARS-2 CPQ) will be discussed during this training. It is an unscored form completed by the parent or caregiver of the individual being assessed and includes the individual's early development; social, emotional, and communication skills; repetitive behaviors; play and routines; and unusual sensory interests.
