Teacher retention has been a challenge for most schools for several years. High-needs schools have been known to have twice the trouble with teacher retention as schools not considered high-needs. The purpose of this study was to identify effective practices school principals can implement to retain teachers at high-needs, urban secondary schools. This quantitative study called on teachers from high-needs schools in Iowa to complete a survey identifying principal qualities related to retention, perceived reasons for teacher attrition, and reasons they continue to teach at their current school. Three hundred eighty-five teachers from five different Iowa school districts participated in the study. The findings of the study suggest teacher attrition and retention revolves around three main elements--Leader Member Exchange (LMX), teacher allocations, and school climate.
