Adult High School Diploma

Adult students can earn credits toward completion of a high school diploma under the guidance of an instructor and support staff. Coursework is offered in small group instruction, computer aided instruction, and individual study. A cap and gown graduation is held on the Mt. SAC campus in June to honor students receiving high school diplomas.

Credits for the required courses and/or electives may be awarded in the following ways (Accredited Institutions only):

  • Adult School Courses
  • Previous High School Courses
  • Work Experience (Must be verified)
  • College Credit
  • Training Programs
  • Out-of-Country/International Schools (transcripts must be evaluated by an approved evaluation service)
