The purpose of this report, one of several prepared for a comprehensive study of early childhood education in Illinois, was to collect, compile, and analyze specific data concerning early childhood education policy and practices from all fifty states. Each state was queried regarding the following: (1) compulsory attendance age, (2) mandated age/cut-off date for entry into kindergarten, (3) local district criteria for entry into kindergarten (particularly where statutes permit local discretion), (4) screening/testing requirements, (5) mandated and/or recommended class size for kindergarten through third grade, (6) problems associated with entry age and screening, (7) competencies/testing requirements associated with promotion to first grade, and (8) recent or proposed legislation for changing kindergarten policies. Descriptions of each state's kindergarten requirements are provided. Problems associated with early childhood education and the resulting recent changes in kindergarten policies are indicated. Charts and graphs in the appendices show survey information for all fifty states, detailing each state's mandates and policies. (DST)
