This report examines the placement of Teach for America (TFA) teachers and examines their impact on the learning gains of their students during 2012-13. TFA is an organization that recruits and trains recent college graduates/professionals to teach for two years in selected communities. Sets of eligible TFA teachers were identified in 2012-13 including all TFA teachers assigned to teach language arts and/or mathematics to students in grades 3 through 10. The comparison pool included all non-TFA teachers assigned to teach students in grades 3 through 10 in schools with TFA teachers, who did not previously participate in the TFA program. Data used in this analysis were obtained from archival records supplemented by data from the student database system and weighted student learning gains computed by the Florida Department of Education (FLDOE) and described in Florida Department of Education (2012). When the learning gains made by students of TFA teachers are compared with those made by students of their non-TFA counterparts who were assigned to similar courses, a consistent impact in senior high mathematics was found, that manifested when weighted learning gains were compared. No consistent benefit in reading was found. As weighted learning gains assign extra bonus points for growth seen among students who are already proficient, this finding supports the notion seen in that TFA teachers are more effective teaching proficient students in standard education and advanced mathematics courses.
