Class of '74 (and later Class of '75) was a secondary school-based, daily soap opera produced by the Reg Grundy Organisation and screened on the Seven Network in Australia starting March 1974. The main characters were a mix of teachers and other school personnel, and students. The series was aimed at a teenage audience. Each episode was 30 minutes; five episodes each week were broadcast, stripped across week nights in an early evening timeslot.
