Homeschooling is quickly becoming a significant educational phenomenon. According to the Indiana Department of Education, the number of Indiana homeschooled children has increased by 400 percent over the past eight years, with a current enrollment total of 22,403. Furthermore, this number likely understates the true number of Indiana homeschooled students, and reflects a constant refrain in research on homeschooling: very little comprehensive data exist on homeschooling demographics, practices, and outcomes. This "Education Policy Brief" describes the current homeschooling landscape and its legal status in Indiana, as well as explores the issues underlying ongoing debate about whether homeschooling merits additional state regulation or oversight.
