Early childhood educators are expected to provide the children in their centers high-quality care and preparation for later school success. At the same time, nearly a third of children enter early care and education settings displaying challenging behaviors, which in turn impacts educators’ stress levels and wellbeing. It is then unsurprising that classroom management and providing behavioral supports are consistently identified as areas where educators require further training upon entering the workforce. The purpose of this study is to conduct a systematic review of the empirical literature on professional development (PD) approaches targeting these areas for early childhood professionals. Forty-two studies were identified as meeting inclusion criteria and were coded for strategies targeted, the context and characteristics of the PD series, and the research design and outcomes utilized.
