For some trades it's a BMQ-L, NETP, BAEQ, PLQ, INELP/whatever the air force and army call the week of BS, ILP issue.
I have never been qualified(without qualifier) for a rank since Cpl. I did my QL6A before my PLQ, I was QL6B before my RQ Sgt, and now I'm A/L WO because my trade was at least 12 months behind before COVID-19 managed to destroy all training schedules. I am extremely unlikely to get an ILP before circumstance and TOS see me release...
In my two years running the weather office in Trenton I never had the ability to send more than one person on training at a time, apparently the RCAF felt that flying was more important than my troops getting career courses. Now according to the army types(because the course before promotion types are always army) my people should be Pte's, not because they can't do the job well, but because Wainwright/Shilo/Pet/Gagetown can't run enough BMQ-L courses to accommodate the support pers and army pers required to take the course.
