Libraries, museums, parks departments, historical sites, scout and sport programs, local businesses, religious groups, and theater groups expand homeschooling programs. Some homeschool groups have formed their own sports teams, and participate in community leagues. Homeschoolers benefit from volunteering in agencies such as hospitals, nature centers, museums, parks, libraries, and businesses. Homeschooling is legal in all 50 states, Canada, and many other countries. Some permit a homeschool to register as a private school.
Many states require yearly proof of student progress.
Some states have additional requirements, such as the submission of a curriculum plan or education requirements for parents. Except for yearly standardized testing as an assessment of student achievement, services for homeschoolers have not been routinely available from the states. A few states permit homeschooled students to participate in public school classes or activities. Many state education agencies have a homeschooling liaison to help families understand state requirements. Federally mandated special education services may be available to homeschooled students through the public schools.
