New National Website Is a Great Source for Evaluations of Intervention Programs
The National Center on Intensive Intervention (NCII) is a new resource that provides educators with evaluations of commercially available intervention programs. NCII is a good source for educators because the reviewers consider a study’s design, purpose, fidelity of implementation, and assessment alignment. In contrast, What Works Clearinghouse (WWC) only considers a study’s design. (Consequently, WWC has posted reviews of Read Naturally where the study authors have told WWC that their studies should not be used as reviews of Read Naturally.)

NCII has posted three reviews of Read Naturally:

These moderate to large effect sizes demonstrate Read Naturally’s statistically significant impact on fluency, rate, accuracy, and comprehension.
