This report presents results from a new quantitative synthesis of research on the effectiveness and validity of test accommodations for English language learners (ELLs) taking large-scale assessments. In 2006, the Center on Instruction published a review of the literature on test accommodations for ELLs titled "Practical Guidelines for the…

As the ongoing national indicator of what American students know and can do, the National Assessment of Educational Progress (NAEP) in Reading regularly collects achievement information on representative samples of students in grades 4, 8, and 12. Through The Nation's Report Card, the NAEP Reading Assessment reports how well students perform in…

This document sets forth recommendations for the design of a new science assessment. The assessment resulting from this framework will start a new NAEP science trend (i.e., measure of student progress in science) beginning in 2009. This framework represents a unique opportunity to build on previous NAEP science work as well as key developments in…

This paper examines how controlling statistically for baseline covariates (especially pretests) improves the precision of studies that randomize schools to measure the impacts of educational interventions on student achievement. Part I of the paper introduces the concepts, issues, and options involved. Parts II and III present empirical findings…

This report examines a Massachusetts pilot program for quarterly benchmark exams in middle-school mathematics, finding that program schools do not show greater gains in student achievement after a year. But that finding might reflect limited data rather than ineffective benchmark assessments. Benchmark assessments are used in many districts…

When it comes to teacher preparation, the support provided to new teachers, and ongoing professional development for working teachers, Grades K-12 and the field of early care and education (ECE) are two very different worlds. While both worlds assume that teachers' classroom skills and behavior can be influenced at multiple points in time (through…

This paper aims to broaden the discussion about effective teacher preparation by exploring three hypotheses designed to expand the early care and education (ECE) research agenda: (1) Both the content and the method of delivery of an educational degree influence teacher practices; (2) Teachers' ability to apply knowledge and skills effectively…

The Citizenship Education Longitudinal Study, conducted by the National Foundation for Education Research (NFER) on behalf of the Department for Education and Skills (DfES), aims to identify, measure and evaluate the extent to which effective practice in citizenship education develops in schools so that such practice can be promoted widely. The…
