In 2012, Tennessee began a series of bold new initiatives to turn around its lowest performing five percent of schools, known as Priority schools. Building on previous research, this brief examines student achievement gains five years into the implementation of the two largest school turnaround efforts - the state-run Achievement School District and district-led iZones. Results are consistent with past evaluations of these two initiatives with iZone schools sustaining positive gains in student achievement throughout the period, while ASD schools did no better or worse than other low performing schools.
Key Findings:
-->
· Overall, through five years of
implementation, iZone schools have positive and statistically significant effects
on reading, math, and science test scores relative to Priority schools
receiving no interventions. The size of the gains in iZone schools are
comparable to other successful school turnaround interventions across the U.S.
· Overall, ASD schools did not gain more
or less than Priority schools receiving no interventions during the five years
of implementation.
· Across each of the five years, iZone
schools show mostly positive effects on student test scores, though these
results are not always statistically significant. These results suggest that
iZone schools have been relatively successful in sustaining the positive
results they were able to achieve early on.
·
ASD
schools did not gain more or less than comparison schools in any of the five
years of turnaround intervention, including after four or five years of
turnaround interventions.
