WWC Summary of Evidence for this Intervention
Accelerated Reader
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.
