Apparently in response to Daniel Denvir’s article accusing the state of Pennsylvania of dragging its feet on an investigation of cheating on state tests, the state released some information.

Just remember whenever you hear a governor or other politician boasting about test scores that they have no idea (and neither will you) whether the gains were produced by mindless test prep (where students learn how to guess the right answer), by teaching to the test (where teachers abandon their professional ethics), or by cheating (by teachers or principals or students or superintendents or the state education department).

In a high-stakes environment, the pressure to raise scores renders them meaningless. See “Campbell’s Law.”
