The new program proved to be, by Griffith's own admission, "a very bad show" and was routinely beaten in the Nielsen ratings by both The Partridge Family on ABC and The Name of the Game on NBC. When this pattern became apparent, production of Headmaster was terminated, with the last first-run episode being broadcast January 1, 1971, and the program replaced by a new situation comedy starring Griffith, The New Andy Griffith Show.
Headmaster marked the return to series television of Griffith, whose previous eponymous show had been one of CBS's major hits of the 1960s prior to his voluntary departure and a program which was still in production (as Mayberry R.F.D.), when Headmaster was launched. With Headmaster, Griffith fulfilled his desire to be cast in a television series as something other than a rural bumpkin dispensing folksy wisdom; here his character, Andy Thompson, was the headmaster of a prestigious Californian private school, the Concord School.
The show's theme song was performed by Linda Ronstadt.
Ron Howard played a student in an episode.
