"Teach For America" ("TFA") is a highly selective route to teacher certification that aims to place non-traditionally trained teachers in high-need public schools. The What Works Clearinghouse (WWC) identified seven studies of teachers trained through "TFA" that both fall within the scope of the Teacher Training, Evaluation, and Compensation topic area and meet WWC group design standards. The WWC considers the extent of evidence for teachers trained through "TFA" on the academic achievement of students in grades pre-K-12 to be medium to large for two student outcome domains--mathematics achievement and English language arts achievement--and small for two student outcome domains--science achievement and social studies achievement. "TFA" teachers were found to have positive effects on mathematics achievement, potentially positive effects on science achievement, and no discernible effects on social studies achievement and English language arts achievement for students in grades pre-K-12. The WWC identified 24 eligible studies that investigated the effects of TFA teachers on the academic achievement of students in elementary, middle, and high school. Three studies are randomized controlled trials that meet WWC group design standards without reservations, and four studies use quasi-experimental designs that meet WWC group design standards with reservations. The three studies the meet WWC group design standards without reservations are: (1) Clark, M. A., Chiang, H. S., Silva, T., McConnell, S., Sonnenfeld, K., Erbe, A., & Puma, M. (2013). "The effectiveness of secondary math teachers from Teach For America and the Teaching Fellows programs" (NCEE 2013-4015). Washington, DC: National Center for Education Evaluation and Regional Assistance, Institute of Education Sciences, U.S. Department of Education (ED544171); (2) Clark, M. A., Isenberg, E., Liu, A.

The four studies that meet WWC group design standards with reservations are: (1) Henry, G. T., Purtell, K. M., Bastian, K. C., Fortner, C. K., Thompson, C. L., Campbell, S. L., & Patterson, K. M.
