What Works Clearinghouse


Program Description1

Corrective Reading is designed to promote reading accuracy (decoding), fluency, and comprehension skills of students in grades 4–12 who are reading below their grade level. The program includes four sequential levels that address students’ decoding skills and six sequential levels that address students’ comprehension skills. The levels are designed to target students who need assistance with particular types of reading skills based on the results of Corrective Reading placement tests (see the Teaching section for more details on the different levels). The decoding and comprehension components can be used separately as a supplemental reading intervention or combined for use as a reading intervention curriculum. All lessons in the program are sequenced and scripted. Corrective Reading can be implemented in small groups of four to five students or in a whole-class format. Corrective Reading is intended to be taught in 45-minute lessons four to five times a week.


One study of Corrective Reading that falls within the scope of the Adolescent Literacy review protocol meets What Works Clearinghouse (WWC) evidence standards, and no studies meet WWC evidence standards with reservations. This study included 86 fifth-grade struggling readers from a school district just outside Pittsburgh, PA.3

Based on one study, the WWC considers the extent of evidence for Corrective Reading on adolescent learners to be small for alphabetics, reading fluency, and comprehension. The one study that meets WWC evidence standards did not examine the effectiveness of Corrective Reading on adolescent learners in the general literacy achievement domain.


Corrective Reading was found to have no discernible effects on the alphabetics, reading fluency, and comprehension domains for adolescent learners.

The WWC requests developers to review the program description sections for accuracy from their perspective. Further verification of the accuracy of the descriptive information for this program is beyond the scope of this review. The literature search reflects documents publicly available by April 2009.
