This presentation summarizes the results of tracking education graduates from East Carolina University over five years to evaluate the effectiveness of innovations in their teacher preparation program. They partnered with an external organization to access longitudinal data and track graduates teaching in North Carolina public schools. Their evaluations found no significant differences between ECU and comparison teachers in classroom observation scores, student achievement gains, graduates' self-confidence and job satisfaction. ECU graduates had higher retention rates, with over 90% staying in teaching after five years compared to around 85% of comparison teachers. The lessons learned were to use data to drive program improvements, develop systemic innovations across areas, and continue tracking graduates over time.
