You might try starting at this resource. There are links that might define what you're looking for. Most homeschoolers are either homeschooled all the way through, or homeschoolers looking to finish in public/private schools. :}
A great percentage of your decision will be based on your state's requirements for graduating. Some states simply don't recognize homeschool graduates whether they test well or not, while others recognize homeschoolers who pass standardized testing.
My friends who have high school homeschoolers participate in graduate curriculum. They've been homeschooling throughout their schooling.
I hope someone else comes along with some insight for you. I'm afraid I'm not much help, lol.
