Literacy Training in the British and Commonwealth Forces?

[Hama]

I've heard that in the USA there were certain resources/classes in the miltiary during WW2 to teach basic reading and writing skills to illiterate recruits. For example:

By the summer of 1942 Selective Service's Washington headquarters reported that local boards were "raising hell at healthy young men being rejected because of illiteracy." They ultimately had their way, with the Army absorbing eight hundred thousand illiterates, aliens, and hyphenated Americans, cycling them through Special Training Units where they learned to read and write the language of the country whose uniform they wore. They packed into hastily improvised classrooms, where they struggled through primers especially written for them: Meet Private Pete, and Private Pete Eats His Dinner.

It seems the US Navy did something similar with their 'Sailor Sam' reading primers. Did Britain or the Commonwealth countries have any similar programmes for teaching illiterate recruits?
