Blogger Perdido Street School reports that 45 percent of the teacher ratings for the public schools of Buffalo, New York, were inaccurate. The ratings were outsourced to a company in Utah that acknowledged its errors. Its miscalculations resulted in 1,089 teachers receiving lower ratings than they should have.
The blogger quotes the story in the Buffalo News:
Lower-than-correct scores were given to educators who teach more than one grade level or subject and are required to meet multiple sets of student learning objectives. The company had rewritten its scoring calculations over the summer to enable it to produce scores more rapidly, Rosenthal said. But in doing so, it inadvertently created the calculation error for this group of teachers.
The district’s data chief, Genelle Morris, said a teacher brought the error to the district’s attention. According to the teacher’s manual calculations, she had met her performance targets, but that was not reflected in the online calculations produced by Truenorthlogic. The district checked her calculations and ran them internally through the district’s Information Technology Department and found it could not replicate Truenorthlogic’s scores.
The company soon uncovered the source of the error and the corrected results were posted online for teachers to view late Thursday morning.
Perdido Street adds this observation about the Governor who insisted on creating the evaluation system (APPR) and who insists it is “scientific” and “objective”:
It will be fun to see Cuomo twist himself into a pretzel to defend APPR even as the Common Core/Endless Testing edifice comes down around him.
Make no mistake – he will do just that.
APPR is his baby – his donors wanted it, he pushed for it, when pushback came, he fought to impose it on the state through the budget.
He will not want to admit it is as flawed and error-riddled as the Common Core implementation (which he can blame on NYSED), the Common Core tests (which he can blame on Pearson) or the Common Core curriculum (which he can blame on NYSED.)
When it comes to APPR, he has no one to blame but himself.
