The issue is schools are a business now and they need to keep the customer happy. Teachers who TEACH their curriculum with rigor are punished because the parents aren’t happy with their darlings grades, but a teacher who can make it look good, rarely covers the curriculum (if one even exists for them) and who gives all A’s and B’s is given a good evaluation.
