In theory you can write a 5 year training plan to cover a cadets entire career. Each sqn is different but the ACTOs give a rough idea of your Core training requirements (Classifications, Drill, Shooting, Radio) along with the high priority optionals (Leadership, DofE, fieldcraft) and the nice to haves (NNAS, .
What we do is split the year into four phases
Sept to Dec - Classification topic 1, YFA & Leadership
Jan to Mar - Classification topic 2, Radio & L98 training (with DoE exped training)
Apr - Jun - Classification Topic 3, DoE, BTECs & Competition training
Jul & Aug - Summer Program, Outdoor activities & Sports
Vocational Projects got binned as soon as we went on Ultilearn - they had been become too complicated and sucked up to much time and were hated by cadets & Staff alike. Also going back to basics, BTEC, Competition First Aid, Radio, air recce & aeromodelling all count so I suppose we still do projects but training focused not vocational.
The first thing I would say is actually work out how many training nights you have each year and then plan your strategy accordingly. Don’t try to fill ever night in your strategy - this allows for the cadet run nights, inspections and other random events. Check with your CO and perhaps agree a criteria for each quarter (e.g. one inspection/drill, one fieldcraft exercise, two sports, two interflight) just don’t put to much in otherwise you’ll run out of space.
The comment about getting multiple ideas is a good one BUT plan in yourself otherwise you’ll end up with a program by committee (and watch out for the person who wants have the training program the same as how they had it as a cadet in 1971!).
You’ll need to look at your resources and see what you actually have to work with and try build in systems that feed back into the sqn (e.g. a leadership course where the cadet who did it last year run it the following year). Think about what you want the cadets to achieve, think about how that relates to the aims and why the cadets should be doing it remembering we are a military organisation.
Finally competitions and inspection reports can give you some way to measure and keep score of your training achievements. It’s what the squadron will be scored on higher up the chain so try and use that. Remember that a cadet shouldn’t repeat training unless they really need to.
Hope this all helps.
