Are these things considered?

@MYOS1634 , can you shed more light on this? I fully get that a college looks at the school’s profile, and that a student is viewed in the context of both other students in the school and the courses offered at that school. But what I don’t understand is how much preference colleges give to applicants from certain high schools. I realize that some colleges have established relationships with certain high schools. Of course I am aware that there are some very well known high schools in the country, but they are only a handful of the 37,000.

Is the label of “competitive high school” meaningless?
