Look up the binomial approximation towards normal and get back to us....
The test scores of students within a school are NOT INDEPENDENT variables. OBVIOUSLY. They have the same teachers, the same learning conditions, the same fellow students to study with (or not). You are populating your samples based on which school a student attends - NOT RANDOM.

No. THE SAMPLING UNIT is a student. Where that student attends school is not a decision, that I, as the researcher control, that is we can consider it a random chance he will be at the school he attends.
Jesus man, you really are fricking stupid.
Under your idiotic assumption one could never compare differences in fish between 2 lakes because the fish already live in that specific lake.
