To be eligible for admission to a four-year college or university, you'll almost always need one of the following:
* High school diploma: This is the standard.
* GED (General Educational Development) certificate: This is an alternative credential demonstrating high school-level competency.
* Homeschool diploma: If you were homeschooled, you'll need a recognized homeschool diploma that meets the requirements of the college. These requirements vary by institution.
While some colleges might offer *conditional* admission based on other factors, they will almost certainly require some form of secondary school completion before granting full admission. A Certificate of Completion is typically not sufficient on its own.
