95 Percent Group's Efficacy Studies


Several schools have done efficacy studies to determine if schools using 95 Percent Group’s instructional materials and assessments would demonstrate higher overall reading achievement by the end of the school year. Participating schools were in diverse, high need areas. Effectiveness was studied for both Tier 2 and 3 intervention groups, and class-wide instruction. Study authors included teachers, interventionists and reading coaches.

The general conclusion reached is that “explicit instruction supports the development of foundational skills in reading resulting in higher overall achievement by the end of the school year.”

We would like to thank all of the educators who generously provided their time and effort to participating in this study. We appreciate your dedication, and diligent efforts to make your students better readers.
