Mine was 12 months for A2, then two years later 1 month for A1 and a city and guilds.
Your lad will get the equivelent of apprenticeship or city and guilds recognition at the end though won't he?
If he is that way inclined once he has finished his trade: I spent a week with the training wing blokes from Calw back in march and they are desperately looking for people. So much so that they are extending SNCO blokes into their 50's.
I raise you one week at Keogh on the 'new' blood donation storage and supply course, it was allegedly a week long
it was just power point (the previous course was three days and all practical work) and dull power point at that,
it was almost as bad as the two weeks on Bowman (two weeks of having someone read exactly what was on the power point to us, the whole course could have been done as a booklet)
Approx 18 - 20 months from memory of the DIN, depending on flavour of language (Arabic, Slavonic, Indo-Iranian). Much less of course for WELW, the Western European Language Wing, aka the Well Easy Language Wing.
