God... What is the logic behind all this? Seems completely retarded that you would need the ACC and procedural ratings to be able to work in a tower. Do you have any information regarding the private companies? Last time I looked the salaries were ****e but maybe they have gotten closer to the salaries of Enaire the last few years?

Many ATCOs did this type of training in the UK from the '60s through to the '90s with NATS.
We did 3 years total with classroom work interspersed with field training and towards the middle of the 3rd year you were offered choices as to where your final posting might be or sometimes simply told where it would be, you couldn't choose for yourself. Having expressed a preference for ACS Upper Airspace, I was offered either Farnborough as first choice or Heathrow as second so I chose Farnborough.
On graduation I was thus posted to an MOD research airfield where I actually got to use all the ratings I had studied for in the previous 3 years ie Tower, approach, approach radar, area and area radar plus a later 'add on' of PAR.

It was the same in Sweden many years ago. In my mind the benefit of flexibility does not justify forcing everyone to get all of the ratings - especially not if you have to finance them yourself as you do in Spain.

The question:
How do you become an ATCO in Spain in 2023.

pprune:
This is what we did in UK and Sweden between 1960 and 1990.

:E:)

Congratulations @Nimmer on your retirement two weeks ago!

well thank you.

So, if what you say is true, experienced controllers do not ‘pass’ a tool designed to select people who will be able to become working controllers. Not so much a leveller, more a wholly ineffective and misleading tool.
