ABSTRACT
This chapter outlines the arrangements agreed in 1945 to recruit for the Government Communications Headquarter’s (GCHQ), skills and abilities, and their subsequent modifications. In the last months of 1945, two senior British civil servants corresponded about the size, structure and pay of the post-war signals intelligence organization that was to become GCHQ, the continuation to the pre-war Government Code and Cypher School and its greatly expanded wartime version at Bletchley Park. GCHQ devised its own tests of potential Sigint abilities for the B4’s selection, and someone sensibly suggested that they should also be taken by the A4 candidates. To return to the A and B classes and their creation in 1945 to meet GCHQ’s peacetime requirements for both flair and management: at the beginning of the 1950s, there was an important lurch in the recruitment agreed for them.
