The DofE Award Scheme is excellent and is a clear benchmark that employers can see and understand, unlike qualifications that change every few years.
The ACO supports the delivery of the award by financing it for those who are successfully in completing, an several aspects of the ACO Syllabus align with the DofE. However I would be looking for cadets to be going that extra mile, classifications are a compulsory part of training, and generates its own award with the BTEC Aviation Studies.
There are plenty of other sill options available that can be completed as part of the ACO, and will increase the cadet experience that your unit is giving as a result, some examples, all of which add to the cadet experience;
Ceremonial Drill - Flight/Squadron/Banner/Rifle
The cadets will look a lot smarter, drill becomes more than moving from A-B, can include an inter=flight competition. Allows for NCO development. May encourage your unit NCOs to complete the DI course, and allows them to impart that additional knowledge to the cadets
Marksmanship Training - No8/L98A2/L86A2/L81A2
So this requires a number of qualified staff, but if you include the IWT on a certain weapon, spend time developing the Marksman Principles, and then put this into practice with regular range periods. Hopefully you'll end up with some Marksmans and a skill signed off. Different weapons could be used at different levels.
Start to get some press release, develop social media and gain new cadets as a result of undertaking the DofE Award = bargain!! Make sure you engage with your WingMCO as they should have knowledge and advice that they can share with this group.
If your unit has a flight sim, put together a course of training, that will relate to their classifications for them to work through, potentially building up to an Air Experience Flight at your local station.
All of these could be run as old style Projects, the possibilities go on. The key for the award is that the skill develops during the time period. You could use the Award Scheme as the medium that enables your unit to undertake additional activities.
