I was creating a web form for a client who requested the highest-grade completed for primary and high school and then college.
The original paper form had the following
Circle highest grade completed 1 2 3 4 5 6 7 8 9 10 11 12 College 1 2 3 4
For the web form, I turned these into two dropdowns. Labeling College was easy, but the 1-12 was harder.
Due to space issues, I chose "Compulsory" as grades 1-12 in the US are compulsory, but my project manager felt it wasn't a layman term, so I switched it for K-12, which is what the Department of Education calls it, even though kindergarten is not included.
So, my question is, is there a one-word (or very short phrase) equivalent to Primary + High School?
