To Expeditedescent
Actually no contract made for foreing ATC is Spain, althoug lack of staff is becoming extremely critical. As a member of EU you can apply to enter ATC School when exams are held (once a year). Average 250 places for around 7000 applicants, and as zerouali says, if you canīt read the AENA link, better desist, as Spanish language is compulsory.
If you want some more info, send me a private message.
