At Frederick Douglass Academy in Harlem, principal Gregory Hodge uses the value-added results to alter instruction, move teachers to new classroom assignments and pair weak students with the highest performing teachers. Mr. Hodge said the data for teachers generally aligns with his classroom observations. "It's confirming what an experienced principal knows," he said.
Question. If an "experienced principal" can do the job then why don't they? I know. They're too fracking busy sifting through data instead of being instructional leaders. Also, how much do company's like SAS Institute Inc. make on Value Added Data Systems? I'll bet you taxpayers pay more for these data systems than the they would for an "experienced principal."
