The proposed study will examine associations among teaching team characteristics, classroom quality, and child outcomes within a large Head Start agency. This quantitative study will examine data from Head Start toddler and preschool teaching teams and classroom children. The study will use 2015-16 data collected by the Early Childhood Education Institute (ECEI). As part of the 2016 spring staff survey, teachers self-reported on the characteristics and perceived effectiveness of their classroom teaching team.
