Go ahead man!
I have 4 weeks left of my training at Swedish Air Traffic Services Academy myself!
The world needs more good controllers!
The qualifications etc is very different from country to country, but in general you need to pass medicals equal to that of a airlinepilot. You allso need to have high stress tolerance, and be able to handle much information at the same time. In Norway (I'm employed by the norwegian CAA) the tests are somewhat similar to the ones used for future fighterpilots, with a stress on visual conception and ability to handle sources of information simultaneously.
The ability to work well with other people is vey important, even in a hectic work inviroment.
In most european countries you need a highschool (or simillar) diploma with fairly high grades, but some (i belive france) require college diplomas. (Which is total B.S, ATC is not something you can learn at Sorbonne...)
I know that Australia has sendt ATC trainees to Bailbrook College in the UK, a ATC academy in Bath that Norway has used previously.
It takes approx 2-3 years, depending on the size and complexity of the ATC unit which will give the final sertficate of validation.
It's often approx 18 moths in an ATC academy followed by 6-12 moths on the ATC unit.
Give it a go!! I can recomend it!!
