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 reading various texts and responding to those texts by answering multiple-choice and constructed-response questions. The information NAEP provides about student achievement helps the public, educators, and policymakers understand strengths and weaknesses in student performance and make informed decisions about education. The 2011 NAEP Reading Assessment will measure national, regional, state, and sub-group achievement in reading but is not designed to report individual student or school performance. The assessment will measure students' reading comprehension and their ability to apply vocabulary knowledge to assist them in comprehending what they read. The reading assessment will use the same framework used in 2009. This document, the "Reading Framework for the 2011 National Assessment of Educational Progress", presents the conceptual base for, and discusses the content of, the assessment. It is intended for a broad audience. This report contains three chapters: (1) Overview; (2) Content and Design of NAEP in Reading; and (3) Reporting Results. Appendices include: (1) Glossary of Terms; (2) NAEP Reading Achievement Level Definitions; and (3) Special Studies: NAEP Reading Framework. A bibliography is included. (Contains 6 footnotes and 12 exhibits.)[To view the 2009 report, see ED502953.]
