Peter Greene is unimpressed by the claim that excuses charter schools have solved the problem of low scoring students. 'Discipline! SLANT! No excuses! Sarah Cohodes concludes this kind of research is hard to design well. She used lottery studies & observational studies in her research. Having scanned the research, she drops this right in this intro:“The best estimates find that attending a charter school has no impact compared to attending a traditional public school.' S he wants to see an expansion of charter practices into public schools; she sees ESSA as a policy tool to do it. But what practices? Besides the questionable morality of such an approach, a vast number of parents simply wouldn't stand for it. And how would we replace the mission of public education-- to educate all students-- with the mission of No Excuse charters-- to educate only those students who are a 'good fit.'
