Failed Classes and Credit Recovery: Students who have failed a required class, will need to make it up and earn a passing grade of at least a D in order to graduate. There are a variety of credit recovery options available to students at TOHS. Students who have failed an elective are not required to make up the course. However, they will not earn credits toward the 230 credits necessary to graduate. They will need to recover the credits lost by taking the class over or through other course work. To learn more about the credit recovery options at TOHS, such as summer school, adult school, and more, please see your counselor.
