This report updates and extends the work presented in Technical Adequacy of Assessments for Alternate Student Populations (Rabinowitz & Sato, 2005). The evaluation is ongoing and is intended to inform developers and consumers of assessments for special student populations (English language learner [ELL] students and students with disabilities [SWDs]). The evaluation focuses on the technical adequacy of evidence related to assessments used to meet relevant Title I and Title III requirements under the No Child Left Behind Act of 2001 (NCLB). The report includes a description of the process and the technical criteria used and summaries of technical evidence related to specific assessments. Summaries of additional assessments will be added as they are completed.
