This study of 952 fifth and sixth graders in Washington, DC, and Alexandria, Virginia, found that students who were offered the "Higher Achievement" program had higher test scores in mathematical problem solving and were more likely to be admitted to and attend private competitive high schools. "Higher Achievement" is a multi-year afterschool and summer program aimed at middle school students from at-risk communities. The program's goal is to improve academic achievement and encourage matriculation into an academically competitive high school. This study is a well-executed randomized controlled trial that meets What Works Clearinghouse (WWC) evidence standards without reservations. The following are appended: (1) Study details; (2) Outcome measures for each domain; (3) Study findings for each domain; and (4) Supplemental findings by domain. A glossary of terms is also included.
