Children Have Opportunities in Classrooms Everywhere Act This bill allows tax-exempt distributions from qualified tuition programs (known as 529 plans) to be used for additional educational expenses in connection with elementary or secondary school. The bill also allows certain federal funds for elementary and secondary education to follow a student from a low-income household to the public school that the student attends or for tax-exempt educational expenses. Under current law, tax-exempt distributions in connection with elementary or secondary school are limited to tuition for a public, private, or religious school. The bill allows these distributions to be used additionally for curriculum and curricular materials, books or other instructional materials, online educational materials, tutoring or educational classes outside the home, testing fees, fees for dual enrollment in an institution of higher education, and educational therapies for students with disabilities. Distributions may also be used for tuition and the purposes above in connection with a home school (whether treated as a home school or a private school under state law). In addition, the bill directs state educational agencies to allocate grant funds to ensure the funding follows students to their public school or for other tax-exempt educational expenses outlined by the bill. Each state that carries out these allocations must establish a plan that allows the parent of an eligible child to apply for grant funds.
