Its not WRT OT, it is about reg's for Reassignment.
IAW CFAO 11-12, a Pte who is not QL3 qualified is entitled to request a MOC Reassignment.
Additionally, the BTAGs (Basic Trg List Admin Guide) amplify that with:
- a NCM can also request a Voluntary Occupation Reassignment (VOR) if they have commenced QL3 trg and are "25% or more, but less than 75% complete" of the QL3 course (seriously, its in the BTAGs, vetted it last week for someone).
Aside from the entitlement to apply, many other things come into play (strength of current/desired MOCs, CFAT scores, Med Cat, etc) SO...the best advice you can be given is to submit a memo requesting your MOC Reassignment and appointment with the PSO (Personnel Selection Officer) before your QL3 start date, or if you are already on QL3, to wait until you hit that "more than 25%, less the 75% complete", and submit your memo requesting VOR and a PSO appointment to your Course CofC.
There is no quaruntee you will get it, however you can't be stopped from applying (or, well you shouldn't be).
If the OP is serious, you might want to get a copy of applic regs (CFAO 11-12 and BTAGs) and talk to your immediate supervisor sooner than later.
Reassignment is one of those things most people never hear of or deal with unless they are at CFLRS, or QL3 level MOC TEs, PSO office, its a pretty uncommon portion of the CF outside those specific org's IMO. Its just part of my 'UFI stash'.
