The high-profile episode underlines some of the pitfalls of grading schools.
“It should give us pause,” said Anne Hyslop, an education analyst at the New America Foundation, a left-leaning think tank. “Any accountability system should be examined, analyzed and updated as needed. You may see some states changing their A-F systems or looking for other models, but it’s a little bit too early to tell.”
Maine, which unveiled school report cards for the first time in the spring, changed the grades for three of 600 schools after errors were caught in the calculations and made those changes public, said Samantha Warren, a spokeswoman for the state education department.
“If there are legitimate things that got screwed up within the accountability system, you want to make sure everyone understands what you did and why,” said Kathy Christie of the Education Commission of the States. “You do not want to do that in a backroom.”
