Assessment 101 is an essential course for educational diagnosticians involved in the assessment and identification of special education students. It covers special education disability/eligibility criteria, fundamental statistical knowledge, and a basic understanding of CHC theory, which are all crucial components of the assessment process. During this session, participants will review special education disability/eligibility criteria and how to assess the 13 different eligibilities under special education. Fundamental statistical knowledge is an essential aspect of the assessment process; participants will review statistical measures provided by norm-referenced assessments. Another critical aspect of Assessment 101 is a basic understanding of CHC (Cattell-Horn-Carroll) theory as it applies to identifying specific learning disabilities. This session is aligned with the Evaluation and reevaluation component(s) of the TEA-required self-assessment and SPP Indicator 11.
