I assume you mean "Applied Behavioral Analysis" by "ABA," and your problem is convincing some people to let you into a school district ABA program
without being enrolled in public school. Do I have that right?
I don't know, but my impression is that such services which are open to public school students are often required by law to be supplied to homeschooled children. Have you checked with
HSLDA? It might be a good idea to get in touch with them on Monday for a little quick counselling.
