$21-4$ Public School Principals

Each year, public schools are rewarded with bigger budgets for achieving a rating of $$excellent$$ or $$recommended$$ and are punished for rating $$needs improvement$.$ These ratings are based on meeting thresholds on a broad set of measures such as attendance rates, graduation rates, standardized test scores, SAT scores, and so on$.$ Discuss the incentives for school principals $($who are the agents, in this case$)$ under this scheme and how you might improve them.
