Here completion of 12 years, the second level, theoretical side, has a final exam where each subject has two hours.
(pre requirement for university, from that route)
All results are gaussian, or at least used to be.
If memory serves 5% will fail.
Second level of practical side, maybe a career college, had 5 to 9 scoring.
Full scale was 4 to 10, but school was paid by graduates, so nobody was perfect and practically all graduated.
Employers had also plenty of levels to choose.
Now it's three levels.
3 is for those who know what they should.
2 is for those who at least tried hard.
1 is for do not hire.
Practical side is also reformed from earlier decades.
Old career college time was stretched so that it got a higher EU level status.
Level of education practically remained.
New career college was also created and its level was lowered.
Now all reformed old career college graduates get a title engineer.
The problem is that current graduates are still using the old title scale.
Practical result is that construction foremen are no more, everybody are construction engineers.
For some reason construction foreman education is restarting.
