“Our schools cannot be improved by the blind worship of data. Data are only as good as the measures used to create the numbers and good as the underlying activities. If the measures are shoddy, then the data will be shoddy. If the data reflect mainly the amount of time invested in test preparation activities, then the data are worthless. If the data are based on dumbed-down state tests, then the data are meaningless. A good accountability system, whether for schools, teachers, or students, must include a variety of measures, not only test scores...our schools should be “data-informed”, “not data driven".”
