Beat the Teacher was a 1980s British game show devised by Clive Doig, made by BBC Television and shown as part of Children's BBC on weekdays at teatimes. It ran four days a week from 1984 until 1988.

Each edition featured two contestants, one a school pupil, the other a teacher, who were tested on general knowledge and logic puzzles. Correct answers won the contestant moves on a giant Tic-Tac-Toe board made from rotating cubes.

One, two, or three moves of the board could be earned by answering correspondingly difficult questions. The contestant could then ask for the square of their choice to be rotated according to the number of moves they had been awarded.

For example, if a square displayed a "nought", one rotation would see the square turn blank; two would see it replaced with a "cross", three with another blank and on the fourth turn it would revert back to a "nought". Tactical play would lead to the contestant building up lines of noughts or crosses, for which points were awarded.

A joker card could be played once in each game by either contestant, reversing each square on the board so that all crosses became noughts and vice versa. A bonus was awarded for a full board of noughts or crosses, after which each square on the board would be randomised.

The hosts were Howard Stableford (1984-5), Paul Jones (1986-7) and Bruno Brookes (1988). The theme tune was written by Mike Batt, although this was replaced in the 1988 series by a new theme by Martin Cook.
