The following is a list of test cards used by the BBC at various points in broadcasting.

Test Card A

The world's first television test card to be broadcast, Test Card A made its debut in the late 1940s. However, it and Test Card B were soon replaced by the more useful Test Card C.

Test Card B

Test Card B is an early BBC television test card. It was very similar to Test Card A but was never broadcast. The original card has since gone missing.

Test Card C

Test Card C is a BBC television test card first broadcast in 1948. It was the first test card to resemble the famous Test Card F.

Test Card D

Test Card D was a BBC television test card first broadcast in 1964. This was the first test card to be based on a specification.

Test Card E

Test Card E was a television test card designed in 1964 and made to accommodate the 625-line system on BBC TWO, as opposed to the 405-line system of Test Card D. However, it only lasted one day on television, and was soon replaced by a modified version of Test Card C. This lasted until 1967 when the colour Test Card F was introduced.
