Head of the Class is a sitcom aired on ABC from 1986 to 1991 that follows a group of gifted students in the Individualized Honors Program (IHP) at the fictional Monroe High School (later Millard Fillmore High School) in Manhattan, and their history teacher Charlie Moore (Howard Hesseman). The program was ostensibly a vehicle for Hesseman, best known for his role as radio DJ Dr. Johnny Fever in the sitcom WKRP in Cincinnati. Hesseman left Head of the Class in 1990 and was replaced by Billy Connolly as teacher Billy MacGregor for the final season.
