What Works Clearinghouse


Report Summary

Effectiveness

Accelerated Reader was found to have no discernible effects on reading fluency, mixed effects on comprehension, and potentially positive effects on general reading achievement.

Program Description

The Accelerated Reader program is a guided reading intervention in which teachers are closely involved with student reading of text. It involves two components, the Accelerated Reader software and Accelerated Reader Best Classroom Practices (formerly called Reading Renaissance). The Accelerated Reader software is a computerized supplementary reading program. Accelerated Reader relies on independent reading practice as a way of managing student performance by providing students and teachers feedback from quizzes based on books the students read. Accelerated Reader Best Classroom Practices are a set of recommended principles on guided independent reading (or teachers’ direction of students’ interactions with text) that ensure Accelerated Reader is implemented with integrity.

Research

Two studies of Accelerated Reader meet the What Works Clearinghouse (WWC) evidence standards. One of the studies evaluated 572 students from grades K to 3 attending 11 schools in a southern school district in the United States. The second study included 32 students in grade 3 attending one school in the Pacific Northwest.

Based on these two studies, the WWC considers the extent of evidence for Accelerated Reader to be medium to large for comprehension and small for reading fluency and general reading achievement. No studies that meet WWC evidence standards with or without reservations examined the effectiveness of Accelerated Reader in the alphabetics domain.
