"Accelerated Reader" is a computer-based reading management system designed to complement an existing classroom literacy program for grades pre-K-12. It is designed to increase the amount of time students spend reading independently. Students choose reading-level appropriate books or short stories for which Accelerated Reader tests are available and read at their own pace. Once students finish reading a book or short story, they take a multiple choice quiz that measures their reading performance and vocabulary growth. The computer-based management system provides students with immediate feedback on their performance and keeps records to help teachers and parents track students' attempts to reach their goals. The What Works Clearinghouse (WWC) identified 13 studies of "Accelerated Reader" for English Language Learners that were published or released between 1983 and 2008. No studies of "Accelerated Reader" that fall within the scope of the English Language Learners (ELL) review protocol meet WWC evidence standards. The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of "Accelerated Reader" on ELL.
