I believe I have heard that there is some mechanism for homeschoolers to become eligible for HOPE scholarships, but I haven't really looked into it.
In our state, the top 10% students at each school are eligible for free community college education. I do know that homeschoolers are not eligible for that program, so homeschoolers here do pay for the dual-credit courses on their own. (The parents and schools are calling the courses dual-credit, but I’m not sure how it works yet.) Also, each community college here has a different policy; some are more homeschooler-friendly than others.
