The 2008 State Preschool Yearbook is the sixth in a series of annual reports profiling state-funded prekindergarten programs in the United States. This yearbook presents data on state-funded prekindergarten during the 2007-2008 school year. The 2008 Yearbook is organized into three major sections. The first section offers a summary of the data, and describes national trends for enrollment in, quality of, and spending on preschool. The second section presents detailed profiles outlining each state's policies with respect to preschool access, quality standards, and resources for the 2007-2008 program year. In addition to providing basic program descriptions, these state profiles describe unique features of a state's program and recent changes that can be expected to alter the future Yearbook statistics on a program. Profile pages are again included for states without state-funded programs. A description of our methodology follows the state profiles. The last section of the report contains appendices, which are available online only. The appendices include tables that provide the complete 2007-2008 survey data obtained from every state, as well as Head Start, child care, U.S. Census, and special education data. The Yearbook seeks to improve the public's knowledge and understanding of state efforts to expand the availability of high-quality education to young children in the 21st century.
