It was reconstituted and renamed the Isle of Man Board of Education in 1946.
Its function was to oversee and provide funds to the elected local school boards, and after 1920 to the popularly elected Isle of Man Central Education Authority which replaced them.
As the Isle of Man Government gained greater autonomy after 1950, a separate Education Authority of 24 elected members, parallel to and rivalling the House of Keys, became increasingly anomalous and unwieldy, but it proved very tenacious of life.
An attempt to rationalise the system in 1968 resulted only in the merger of the Authority with the Board, which thereafter consisted of 5 "Tynwald members" appointed by Tynwald and 24 elected "non-Tynwald members", the former having control over finance and certain powers of veto.
The Board was reconstituted as a body of 15 elected members with greatly reduced functions; in effect it became a panel from which members of the governing bodies of primary and secondary schools and the Isle of Man College were drawn.
