IES | What Works Clearinghouse

The What Works Clearinghouse (WWC) is a trusted source of scientific evidence on education programs and solutions that works to answer the question, “What works in education?” As part of the Institute of Education Sciences in the U.S. Department of Education, WWC reviews research, determines which studies meet rigorous standards, and summarizes the findings to inform decisions and improve student outcomes.

In recent years, the WWC has not regularly updated their reviews of literacy programs, and studies listed for most education publishers are from prior to 2014. Despite the fact that the WWC has not reviewed Reading Plus’ most recently submitted research, it has found Reading Plus to have potentially positive effects on comprehension for adolescent learners. Learn more about Reading Plus’ WWC Summary of Evidence, which includes a thorough study of Miami-Date regions II and III reflecting statistically significant positive effects, examining 13,128 students in grades 5-9 across 98 schools.
