They have higher standards for decorum and appearance, but not higher academic standards. One of the advantages of private schools is that they are essentially exempt from standards. Their students are generally not required to take standardized tests, and the schools generally are not required to follow prescribed curricula. I agree that private schools generally have a higher standard of cleanliness and facility upkeep. And although the families have to pay more for students to attend compared to (free) public schools, teachers as a broad class are paid less, not more, at private schools. There are numerous reasons for this. For one, a prospective employee has even less leverage than they do when seeking employment at a public school.
