What country are you from and do you call it 1) elementary, junior high, high school 2) elementary, middle school, high school, 3) primary, ???, secondary?
Fyi: it's called post secondary because, I think, UK calls it primary, secondary, and after that is post secondary.
Texas, US. We called it Elementary (optional Pre-K, required K through 5), Middle (6 through 8), and High (9 through 12). They're called Primary and Secondary when filling out forms or legal documents.
Also Texas, US (grew up in Lubbock graduated 96) we had Elementary (K-6), Jr High (7-9), and High School (10-12). Now I live in Plano and have kids in school here. The specific area we are in has Elementary (K-5), Middle School (6-8), High School (9-10), and Sr High (11-12). 🤷♂️
