With over 50,000 educational products for kindergarten through 12th grade as of 2015, Rainbow Resource is one of the largest online suppliers of home school textbooks. Parents can also purchase textbooks at a home school convention, from other online sellers or at curriculum sales sponsored by local home school groups.
Parents often evaluate and select home school curricula by visiting a state or regional home school convention. There, vendors directly sell many textbooks and other educational resources. Parents also order textbooks from large publishers such as A Beka or Sonlight or from booksellers such as Amazon.com. Local home school groups also provide valuable advice on textbook selection. These groups often organize used textbook sales at the end of each school year.
