Research on teacher turnover has led to the identification of retention strategies to help advance the profession and improve the recruitment, preparation, and support of teachers. This report summarizes available research on these strategies and discusses potential barriers and research on their relative cost-effectiveness.

This analysis examined the cost effectiveness of research from Stuart Yeh on common sturctural interventions in education. Additionally, The Wing Institute analyzes class-size reduction using Yeh's methods.

It is important to select interventions that have the greatest impact we can afford. Using Stuart Yeh’s effectiveness cost ratio formula, a rough comparison can be drawn comparing class size reduction with other educational interventions.
