Session Submission Type: Symposium
Alternate assessments based on alternate achievement standards (AA-AAS) are an area that elude most psychometric measurement and models. There are a host of reasons for this, including small, non-normal samples, and not meeting many of the complex psychometric assumptions of the current models being developed, studied, and debated. This session incorporates many of the psychometric issues faced by AA-AAS and Modified assessments including: the applicability of IRT (parametric and non-parametric) to AA-AAS; appropriate longitudinal matching and analysis for AA-AAS; a comparison of growth for students with and without disabilities; and an examination of classroom artifacts on an AA-AAS. Four papers are presented that focus on different elements of assessments for students with disabilities.
