The ECERS-3: Identifying Gaps and Equity Challenges project was designed to interrogate the Early Childhood Environment Rating Scale-Third Edition (ECERS-3) with an equity lens. The project included focus groups with Black and Hispanic/Latine users of the ECERS-3; secondary analyses of an existing ECERS-3 dataset; and classroom observations using the ECERS-3 and another observation tool, the Equity in Early Learning Assessment (EELA), which was designed to assess socio-cultural aspects of classrooms. These recommendations are based on analyses of data from these three activities.
