My children were among the very earliest of homeschoolers, and were admitted under the “gifted and talented” loop hole that existed for the community college at the time. They completed all their general education requirements, and Calculus III, on the community college level. At this point the oldest attended a private college and the two younger a state university. Both on the community college, and university and private college levels, our children were the very first homeschoolers to be admitted.
There are many more opportunities for homeschoolers now. Thanks to the outstanding successes of my children, and the homeschoolers that followed them, admission to our local community college and state universities is far more routine for young homeschoolers. Also, there are many more courses available through the Internet, and today there are AP tests as well.
Good on you on having such smart kids. I hope I’m as lucky, even though I probably won’t home school.
