Program Description1

Reading Plus® is a web-based reading intervention that uses technology to provide individualized scaffolded silent reading practice for students in grade 3 and higher. Reading Plus® aims to develop and improve students’ silent reading fluency, comprehension, and vocabulary. Reading Plus® is designed to adjust the difficulty of the content and duration of reading activities so that students proceed at a pace that corresponds to their reading skill level. The intervention includes differentiated reading activities, computer-based reading assessments, tools to monitor student progress, ongoing implementation support, and supplemental offline activities.


One study of Reading Plus® that falls within the scope of the Adolescent Literacy review protocol meets What Works Clearinghouse (WWC) evidence standards with reservations. The study included 13,128 students, ranging from grade 5 through grade 9, who attended schools in Miami-Dade County in Florida.3

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


Reading Plus® was found to have potentially positive effects on comprehension for adolescent learners.
