States and districts across the country are grappling with how to incorporate assessments of student learning into their teacher evaluation systems. Sophisticated statistical models have been proposed to estimate the relative value individual teachers add to their students' assessment performance (hence the term teacher "value-added" measures).…

This body of evidence summary reports the results of the evaluation of technical evidence in support of the California English Language Development Test (CELDT), as analyzed against a validated list of technical adequacy criteria. The table presented in this paper outlines the types of validity, reliability, and bias and sensitivity evidence…

The No Child Left Behind Act of 2001 (NCLB, 2002) has produced an explosion of interest in the use of assessment to measure and improve student learning. Initially focused on annual state tests, educators quickly learned that results came too little and too late to identify students who were falling behind. At the same time, evidence from the…

This report describes the purposes of benchmark assessments and provides recommendations for selecting and using benchmark assessments--addressing validity, alignment, reliability, fairness and bias and accessibility, instructional sensitivity, utility, and reporting issues. We also present recommendations on building capacity to support schools'…

Recent research has shown that the technical adequacy of assessments for special student populations is relatively undeveloped compared to their general education counterparts; that is, the technical evidence provided and the methods by which this evidence is established do not necessarily account for the unique characteristics of special needs…

These guidelines, prepared by the Special Populations Strand of the Assessment and Accountability Comprehensive Center (AACC), focus on the technical quality of assessments for English language learners (ELLs) and students with disabilities (SWDs). This document is an evolving document that will periodically be updated to incorporate new…
