Teacher Attrition and Mobility During the Teach For America Clustering Strategy in Miami-Dade County Public Schools
We examine the extent to which clustering large numbers of Teach For America (TFA) corps members in a limited number of low-performing schools was accompanied by changes in teacher mobility decisions. Using longitudinal data from Miami-Dade spanning six school years, augmented with survey responses from TFA’s own Alumni Survey for cohorts placed in the Miami region, we use Cox proportional hazards models and multinomial logit decision models in a modified difference-in-difference (DD) framework. Our results suggest that the increased concentration of TFA corps members in schools was associated with a reduction in TFA mobility across schools after the first year of service, but it did not affect the overall retention of corps members in the district after the two-year commitment. In addition, we find evidence suggesting non-TFA teachers in schools with a relatively high proportion of TFA corps members were significantly more likely to leave the district. We also find that TFA corps members retained beyond the two-year commitment performed substantially better in mathematics during their first two years of teaching: evidence of positive selection into postcommitment retention. Finally, we produce steady-state estimates of the minimum TFA effects necessary for the district to prefer hiring a TFA corps member relative to a non-TFA hire. TFA corps members in the district exceed this minimum value in both reading and mathematics.
