And while their reasons for not receiving a diploma vary widely. From chronic illness or disability to a family crisis, homelessness, criminal records, and more. Most share one thing in common: They want to receive their high school diplomas.

Online high schools for adults provide an opportunity to earn a diploma with the flexibility associated with online learning. They give students who have been out of school for some time and are looking to return the chance to receive their high school diplomas without enrolling in a traditional brick-and-mortar high school.
