Ravitch is 100% correct when she says: "When a grading system produces such bizarre results, it lacks face validity. That is, on the face of it, the evaluation system is suspect."
The mantra coming out of Tweed these days is Accountability, and Bloomberg and Klein have made much of testing and test score comparisons to convince people that they know how to make schools accountable.
But it is clear that from almost every possible angle – different tests, different test-takers (and what side of the bed they woke up on the day of the test), different amounts of accommodation, different degree and quality of prep, different testing conditions, and even different morality in marking – comparisons of test scores do not stand up to scrutiny or further the cause of accountability.
Test score data is useful for one thing only: Spin. And that's the farthest away from accountability you can get.
What, then, are they REALLY trying to do with our schools and our kids?
