Including English language learners (ELLs) in large-scale assessments raises questions about the validity of inferences based on their scores. Test accommodations for ELLs are intended to reduce the impact of limited English proficiency on the assessment of the target construct, most often mathematic or science proficiency. This meta-analysis…

This study examined the percentage of task-sampling variability in performance assessment via a meta-analysis. In total, 50 studies containing 130 independent data sets were analyzed. Overall results indicate that the percentage of variance for (a) differential difficulty of task was roughly 12% and (b) examinee's differential performance of the…

This article describes how one university-based center, UCLA's Center X, has worked to prepare and sustain urban educators over the past 16 years. Synthesizing findings from more than 20 articles, papers, books, and dissertations that report on Center X's work, we argue that three key activities are necessary to spur change and ensure a…

The relationship between functional or life skills curricula (the intervention) and transition-related outcomes for secondary-aged youth with disabilities is explored in this systematic review.
