@blueandgreen - depending on how high your SAT scores are, some colleges may not be interested in any homeschool documentation aside from a transcript (which all colleges will want). I am in the northeast and no college that my children applied to asked for anything aside from a transcript (which I made) and SAT scores (sent in from College Board). That’s it. Had they asked for some ‘you had permission to homeschool’ letter or ‘proof that you actually were homeschooled’ letter, I wouldn’t have been able to comply as I don’t have anything like that from my state. IT just doesn’t exist. So, it’s certainly not something that colleges need.
Just document what you actually did during high school and send in your SAT/ACT scores and include any outside classes (like community college) and you’ll be fine.
Another option is to go to community college for a while and then transfer. If you choose this option, just know in advance what articulation options your college has. One of my daughters did this and it was an excellent option for her. She is now working doing exactly what she wanted in her field (and her degree was far, far less expensive than many of her co-workers).
