We also homeschool and dd hopes to study music in college. Awhile back I found out about a great high school program through a post here on College Confidential. DD is now enrolled with North Atlantic Regional High School (NARHS) and we send her schoolwork to them yearly (with my grading and final grades) and they check over it and make a transcript for her. They are accredited by Middle States Association of Colleges and Schools (MSA-CESS), one of the 7 accreditation bodies that colleges look for. I did this to keep track of her work more efficiently and also to make college/music school application process much easier and streamlined, to avoid sending in labs, trying to prove foreign language, etc. I love that you, the parent, still get to control the curriculum and even self-design some classes tailored to your teen’s interests and extracurriculars. I didn’t know about the program until the end of her freshman year, but I was able to go back and compile her schoolwork/tests to send it all in. It is quite common for families to do so. Their FAQs section and handbook has all of the details. Anyway, I thought that might be helpful to you…Also, PA Homeschoolers has AP classes that your son can take online if he chooses that path instead of community college. He sounds very bright and talented! Best of luck to him.
