Three major investigations were conducted in an effort to determine the impact of home school regulations on educational enrollments in the United States. Home school regulations were obtained from state departments of education and investigated to determine the strength of the accountability measures. Populations representative of the school-age population by state, school enrollment, school non-enrollment, and home school enrollment were collected using 2000 U.S. Census data. The relationship between the strength of the home school regulations and the home school enrollments was examined. Finally, the existence of a discrepant student population was assessed.
