The Ability to Incorporate Religious Instruction
Parents often use this capability to provide their children with a religious education. While by no means do all home school curriculums include religious instruction, unlike public schools it is possible to include the topic as often as a parent would like. In a home school curriculum science, math and other subjects can be taught through religious texts and contain religious-themed lesson plans and assignments. This permits parents to provide their children an education that conforms to their personal beliefs.
Of course, secular education has its benefits. For many parents, even those that home school, separating religion and education is important. A home school curriculum can, but does not need, to be religiously based. The option, however, is attractive to many parents.
