* Some community colleges may offer developmental courses for students who haven't yet earned a high school diploma, to help them prepare for college-level work.
* Some colleges may have specific programs designed for students without a high school diploma, but these are less common.
* Individual courses may have different requirements. Some non-credit courses or continuing education courses might not require a high school diploma.
However, for the vast majority of college programs leading to a degree or certificate, a high school diploma or GED is a fundamental requirement.
