Sorry but Im not to sure how they go about when they select when to run courses,must just wait when there's enough trainees to make it viable i.e between 7-12 (there were 8 on my course from all over the country) Hope you get what you're after,sorry about the rambling response just hope its been of use. Don't hesitate to ask anything I promise to be quicker next time. (I see you're ex-navy,there's a few ex-service on my line so that definitely puts you in good stead regarding your application). PS Had to cut and paste reply as original answer to long for email hence the truncated reply over 3 messages!
