This report presents findings from a survey of Maine's early care and education (ECE) teachers and providers about their experiences related to young children with challenging behavior. These experiences included young children displaying different types of challenging behavior, children leaving the program due to challenging behavior, and teachers' and providers' efforts to address the needs of children experiencing behavior problems. The survey also asked teachers and providers about the resources they need to help them meet the needs of young children with challenging behavior and promote their positive social-emotional development.
