The important factors for a "good" school are: great leadership, high expectations of everyone involved, security and organization of the students, and of course, diversity. One school is noticeable "better" than the other when it shows great management and distribution of knowledgeable and useful materials to the students. Diversity is important because it helps people to be more open-minded and accepting of all individuals regardless of religion, sexual orientation, and skin color. School with diverse population is way better than school who only one or two ethics group, because this results on a narrow perspective of the world and other knowledge that is not found in school textbooks, but to the environment as well.
For example, privilege schools with a huge population of white students who have little to none exposure to POC can result in closemindedness or ignorance of POC's struggles because they are "not used to it" since they only hang-out with people the same as them.
