This mixed methods study seeks to understand and address the prevalent use of expulsion and suspensions practices in early childhood settings. Research has shown that preschoolers, particularly those from low-income families and with challenging behaviors, are experiencing high rates of expulsion and suspension. The goals of this study are to: 1) Gain an understanding of the current status of preschool exclusionary discipline practices (i.e., exclusion and suspension) and thus the need for professional development (PD) and support; 2) Build early educators' competence and confidence in facilitating children's social-emotional development and addressing challenging behaviors; 3) Promote social-emotional and behavioral health of preschoolers with challenging behaviors; and 4) Reduce the use of expulsion and suspension practices in early childhood settings.
