Organization: Institute of Education Sciences, What Works Clearinghouse
The What Works Clearinghouse (WWC) identified nine studies of READ 180® that both fall within the scope of the adolescent literacy topic area and meet WWC group design standards. Three studies meet WWC group design standards without reservations, and six studies meet WWC group design standards with reservations. Together, these studies included 8,755 adolescent readers in more than 66 schools in 15 school districts and 10 states. Read 180 has some positive effects.
