Lithuania
1-8 progimnazija 9-12 gimnazija 11-13 profesinė (vocational)
1-10 pagrindinė (basic) and 1-12 vidurinė (middle) used to exist but almost none of these exist now.
In Russia it was for me just 1-11 grades with the last 2 being optional and the 4th one being suspiciously absent.
US. I had Elementary kindergarten-4th (5-10). Middle school was 5th-7th (/10/11-12/13). Junior high was 8th-9th(13/14-15). High school was 10th-12th (15/16-18/19).
Netherlands:
0.5: Kindergarten - ages 4 and 5
1: Basisschool Onderbouw (elementary part one) - ages 6, 7 and 8.
1.5: Basisschool Bovenbouw (elementary part one) - ages 9, 10, 11, sometimes 12.
2. Middelbare school (High school) - Ages 12 - 16/17/18 depending on what level of education you’re going for.
0.5-1.5 is because they are usually all in the same school.
