Groves Adult High School is a state-approved and regionally accredited program. Groves graduates earn a regular, State of Delaware high school diploma. Enrollment is open year-round, and students can complete credits through in-person classes, computer-based/hybrid classes, or by testing out. Adult high school classes provide an option for students who need to work for financial reasons, have family obligations and responsibilities, need the flexibility of day and evening classes in an accelerated format, or have fallen behind in the traditional school setting and are ready to withdraw.
