Homeschooling procedures and rules vary from state to state. The premise is that the parents do the teaching. Sometimes by direct "lecture", sometimes by access to programs and modules prepared professionally for this purpose. In some situations there are "associations" of homeschoolers which get the children together for social experiences. My understanding is that typically the students are expected to pass certain tests designated by the school board to get an "equivalency" diploma. However, they do not attend the schools physically and don't take classes provided by the school district. The premise (which is arguable) is that "Parents Know Best" about what their children should learn and be exposed to.
