Traditionally, single-sex education has been provided in the form of private schooling. Title IX regulations have loosened as a result of the No Child Left Behind Legislation; therefore, public school districts now have the legal right to create single-sex classes or single-sex schools if they deem it to be in the best interest of their students. In public school single-sex environments, student achievement improves, especially for minority students or students in poverty, as a result of improved behaviors and teacher focus on learning-style differences. The author of this article concludes that school districts should give parents the choice of single-sex education or coeducation by offering single-sex classes or single-sex schools along with coeducation.
