There is growing unease about suspension and expulsion of children at the preschool level. Preschoolers are expelled at three times the rate of K-12 students (Gilliam, 2005). Boys--particularly African-American boys--comprise a disproportionate number of these cases, a fact that has caused concern among parents, policymakers, and advocates alike. These suspensions and expulsions have broad-ranging impacts on children and families across the country. States that received the Preschool Development Grant (PDG) funding have begun to explore and implement policies and practices to mitigate this growing problem. This brief is intended to serve as a resource to these and other states. It sets the stage by detailing why preschool expulsion and suspension rates should matter to states. There is a discussion of relevant federal and state policies as well as various state practices used to impact this issue. The brief concludes with appendices that include excerpts of PDG states' policies or guidelines, and descriptions of their preventive practices. (author abstract)
