Xenolith, I believe that the answer is yes. I was commissioned in 2002 from MACR to Flt Lt on IIRC no 4 WOSP ( Warrant Officer Study Period). The scheme was still going in 2010, the year I retired. The course used to last from Sunday to Friday and was very much on the lines of a grown up discussion. As for a success, several of the course members over the years have continued to progress to Sqn Ldr and I felt it was indeed of value as I went almost straight from Cranwell into the HQ in Oman for the initial push into Afghanistan a real eye opener for an elderly ALM!!!!
