Fyi: it’s called post secondary because, I think, UK calls it primary, secondary, and after that is post secondary.
Czech Republic, and it’s pretty much the same as Slovakia (and perhaps other countries around here.)
Základní škola (elementary, ages ~6+), Střední škola (high school, ages ~15+), Vysoká škola (college, ages ~19+).
Střední škola is sometimes replaced with 4 or 8 years of Gymnázium starting after ZŠ (4-year G.) or after 5th grade (8-year G.) Střední škola is normally focused on a particular field, whereas Gymnázium is more generic and is normally followed by Vysoká škola.
Scotland:
Primary school P1-P7 (~5-11) Secondary school S1-S6 (~12-17)
Germany: 4 years elementary school, after that the kids are divided into 3 school categories based on their performance:
Hauptschule 5-9, after that you either start apprenticeship for 3 years and learn a profession, or you continue with Realschule
Realschule 5-10, after that you either start apprenticeship for 3 years and learn a profession or you continue with Gymnasium
Gymnasium 5-12, after that you may apply for university. You can only enroll in university if you have completed grade 12 final exams (called Abitur)
In Germany kids are required to be enrolled in school or in apprenticeship by law until they turn 18
where I live we have two schools; elementary and middle school/gymnasyum.
The first 4 class of elementary is the “lower”, the last 4 class are the “upper” classes.
after that, university or “main school” is where we go
