Therefore, you cannot assume any college will accept it. You must contact each college's admissions office *directly* to inquire about their policy regarding ACI diplomas. Look for their admissions requirements page on their website, or call/email the admissions department.
Be prepared to explain your situation and provide any supporting documentation they may request. They might ask for additional information, such as your transcript and possibly require you to take placement tests to demonstrate your readiness for college-level coursework.
In short: It's possible, but not guaranteed. Proactive communication with individual colleges is absolutely essential.
