"Fast ForWord"[R] is a computer-based reading program intended to help students develop and strengthen the cognitive skills necessary for successful reading and learning. The program, which is designed to be used 30-100 minutes a day, 5 days a week, for 4-16 weeks, includes three series. The "Fast ForWord[R] Language" series and the "Fast ForWord[R] Literacy" series aim to build cognitive skills such as memory, attention, processing, and sequencing. They also strive to build language and reading skills, including listening accuracy, phonological awareness, and knowledge of language structures. The "Fast ForWord[R] to Reading" series (also known as the "Fast ForWord[R] Reading" series) aims to increase processing efficiency and further improve reading skills such as sound-letter associations, phonological awareness, word recognition, knowledge of English language conventions, vocabulary, and comprehension. The program is designed to adapt the nature and difficulty of the content based on individual student's responses. The What Works Clearinghouse (WWC) identified 342 studies that investigated the effects of "Fast ForWord"[R] on the reading skills of beginning readers. The WWC reviewed 25 of those studies against group design evidence standards. Seven studies (Borman, Benson, & Overman, 2009; Scientific Learning Corporation, 2004, 2005a, 2005b, 2005c, 2006, 2007) are randomized controlled trials that meet WWC evidence standards without reservations, and two studies (Overbay & Baenen, 2003; Scientific Learning Corporation, 2008) are quasi-experimental designs that meet WWC evidence standards with reservations. Those nine studies are summarized in this report. Sixteen studies do not meet WWC evidence standards. The remaining 317 studies do not meet WWC eligibility screens for review in this topic area.
