This report examines the patterns of placement of Teach for America (TFA) teachers and the achievement of the students they taught during the 2018-19 school year. The length of time current and former TFA teachers continue as employees of the District is also explored. TFA is an organization that recruits recent college graduates/professionals to teach for two years in selected communities. All TFA teachers assigned to teach at participating schools within the Miami-Dade County Public Schools are included in the participation section of this report. The analysis of impact was limited to teachers assigned to teach content addressed through state- and district- wide assessments; i.e., reading/English language arts (Grades 1-10), mathematics (Grades 1-10), science (Grades 5 and 8), civics (Grade 7), biology (Grade 10), and U.S. History (Grade 11). Two separate comparisons of the students' impact scores failed to show any significant differences at any grade-level or subject area. Moreover, the size and direction of the differences were unaffected by teachers' assignments. Finally, an examination of the duration of employment of TFA teachers showed that most separate from service one to two years after completing their commitments to the program.
