In the Netherlands, all controllers did their tests during the last few months of 2007. I did mine in November. It's an Australian made test using local RT, not completely ICAO-standard, in my opinion. Anyhoo, the first portion is a listening exercise with multiple choice questions, the second part is basically the same but requires a little more effort and the last part is a speaking exercise in which one has to use standard and non-standard RT. I had an emergency requiring a priority landing, other aircraft holding and internal RT with fire brigade, airport authorities, supervisor etc.
Nothing to worry about really
