NATS needs to get back to basics. You can't start training until you're 18, so applicants should have 2 A Levels under their belts. Maths, Geography, Science or computer based. Failing that, 5 GCSE's with 2 years of relative aviation experience. If candidates have a degree, so much the better. Get rid irrelevant 'aptitude' tests and the layers of HR bods with fluffy job-titles. Get ATCOs out there on the recruiting circuit, and, depending what the WEF (et al), have planned, have a BIG look at present staffing & manpower planning.
