WWC Summary of Evidence for this Intervention
Accelerated Reader™ is a computerized supplementary reading program that provides guided reading instruction to students in grades K–12. It aims to improve students’ reading skills through reading practice and by providing frequent feedback on students’ progress to teachers. The Accelerated Reader™ program requires students to select and read a book based on their area of interest and reading level. Upon completion of a book, students take a computerized quiz based on the book’s content and vocabulary. Quiz performance allows teachers to monitor student progress and to identify students who may need additional reading assistance.
As of December 2009, no studies of Accelerated Reader were found that fell within the
scope of the English Language Learners review protocol and met WWC evidence standards.
Therefore, the WWC is unable to draw any research based conclusions
about the effectiveness or ineffectiveness of Accelerated Reader to improve outcomes in this area.

Grades of the students examined in the studies that met WWC design standards, which may not reflect the full range of grades for which the intervention may be used.
The number of students included in the studies that met WWC design standards.
An indicator of the size of the effect from using the intervention. It is the expected change in percentile rank for an average comparison group student if the student had received the intervention, ranging from -50 to +50. At the domain level, the improvement index is only shown if the effectiveness rating is positive, potentially positive, potentially negative, or negative; dashes are displayed for mixed or no discernible effects. At the study level, the improvement index is only shown if the findings are characterized as statistically significant or substantively important (greater than +10 or less than -10); dashes are displayed for an indeterminate effect.

The indicator represents the highest level of similarity found between your students and each of the high-quality studies of the intervention. Three filled in ovals indicates that at least one study that met standards was conducted on students very similar to yours. Clicking on the indicator for a study will provide information on the similarity for each of the characteristics you selected.
