The Accelerated Reader/Reading Renaissance program (now called Accelerated Reader Best Classroom Practices) is a guided reading intervention in which teachers direct student reading of text. It involves two components. Reading Renaissance, the first component, is a set of recommended principles on guided reading (or teachers' direction of students' interactions with text). Accelerated Reader (AR), the second component, is a computer program that facilitates reading practice by providing students and teachers feedback from quizzes based on the books the students read. The program gives students opportunity to practice reading books at their level, provides feedback on student comprehension of books, and helps students establish goals for their reading. One study of Accelerated Reader/Reading Renaissance met the What Works Clearinghouse (WWC) evidence standards. The study included 910 students from grades K to 3 attending 11 schools in a southern school district in the United States. The WWC considers the extent of evidence for Accelerated Reader/Reading Renaissance to be small for comprehension and for general reading achievement. No studies that met WWC standards with or without reservations addressed alphabetics or fluency. Accelerated Reader/Reading Renaissance was found to have potentially positive effects on comprehension and general reading achievement. [This publication was produced by the What Works Clearinghouse.
