What is it like being an alumni of a school that’s underfunded or neglected? Even if the school is “good” (as in well funded or private), does the learning environment reflect that? Also, the dark side of American schools (shootings) dampens peace of mind for parents since at any given moment some gun wielding individual can storm in murdering those inside (students, teachers, custodians, etc.)
Only in things that are objective, like 2+2=4, or CAT spells cat. That’s going to be same in every school.
Things start to get different when you get to subjects with a subjective perspective like history. Then we end up with 50 different curriculums, being taught from a substandard Texas history book. So teachers in some states like to “supplement” their personal course curriculum with their personal research, and we end up with 150 years of many kids being taught that the Civil War was a war of northern aggression who wanted to take away States Rights, and Slavery had nothing to do with it, blunting the effects of the Civil War, and preserving that same systemic racism that has finally broken free and is rampaging across our nation.
