Program Description1
Lexia Reading is a computerized reading program that provides phonics instruction and gives students independent practice in basic reading skills. Lexia Reading is designed to supplement regular classroom instruction. It is designed to support skill development in the five areas of reading instruction identified by the National Reading Panel.
Two studies of Lexia Reading meet What Works Clearinghouse (WWC) evidence standards and one study meets WWC evidence standards with reservations. The three studies included 314 students in kindergarten and first grade in two states.3
Based on these three studies, the WWC considers the extent of evidence for Lexia Reading to be small for alphabetics, fluency, comprehension, and general reading achievement.
Lexia Reading was found to have potentially positive effects on alphabetics, no discernible effects on fluency, potentially positive effects on comprehension, and no discernible effects on general reading achievement.
