Noted: The release of the individual rankings has even been controversial among the scientists who designed them. Douglas N. Harris, an economist at the University of Wisconsin, where the city?s rankings were developed, said the reports could be useful if combined with other information about teacher performance. But because value-added research is so new, he said, ?we know very little about it.? Releasing the data to the public at this point, Dr. Harris added, ?strikes me as at best unwise, at worst, absurd.?
