USA, 2

Virginia, USA in the 1980s it was:

K-5 Elementary

6-7 Intermediate

8 was just called 8th grade building or maybe junior high

9-12 High School

Ontario Canada Elementary, secondary but it depends on the school. Some are called high school, mine was called secondary school in the 90s but I think it's called a high school these days.

Hong Kong

Kindergarten

Primary (grades 1-6)

Secondary (grades 7-12)

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.

Slovenia.

Osnovna šola (primary school) 1-9 starting at age 6 split into razredna stopnja (class level)1-5 and predmetna stopnja (subject level)6-9.

Srednja šola (secondary) 1-2/3/4 depending on programme or gimnazija (general education secondary) 1-4

Visoka šola (high school) comes after secondary vocational and is usually 1-3

Fakulteta (basically uni) after any secondary that meets criteria usually after gimnazija (you don't have any qualifications by finishing that) 1-3 for dodiplomski študij (bachelor), 1-2 for magistrski študij (masters) and however long it takes to get a PhD

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

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

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.

both 1) or 2) are common in the American Midwest but also primary school or grade school for that first stage

Scotland:

Primary school P1-P7 (~5-11) Secondary school S1-S6 (~12-17)
