Teach for America (TFA) is a national organization with a long-established presence in Houston. The organization recruits recent college graduates and mid-career professionals who commit to teaching for two years in schools with high proportions of economically disadvantaged students (Teach for America, 2017). Since 1991, Houston Independent School District (HISD) and TFA have maintained a twenty-five year partnership in which TFA assists the district with filling high-priority, vacant teaching positions in low-income schools. The purpose of this evaluation is to summarize the frequency and effectiveness of TFA corps members in HISD since 2012-2013.
