Late 60's, 11-B-10 A.I.T. (light infantry training), I recall maybe a couple of hours at most, all in only one day, of basic general familiarization - disassembly/cleaning/reassembly - and firing a few clips through the 1911. No qualification requirements whatsoever. The 1911's we used for training were no telling how old and for the most part all but wore out.
