We already didn’t take A-F Report Cards seriously. They are statistically unreliable. They include calculations with arbitrary weights. And they are more subject to political narratives than they are to reality.
Today, after much fanfare, schools finally received their preliminary letter grades. There were some surprises, but nothing far off the expectations that had been communicated.
Thirty minutes later, that all changed. The SDE had applied their own formula incorrectly. Apparently, someone mistook the top quartile of students in math for the bottom quartile.
They recalculated grades, and schools saw drastic changes. Many dropped by more than a letter grade.
How can anyone continue expecting people to take this seriously? In thirty minutes, we saw the biggest problem with A-F Report Cards. They depend more on the formula than they do on the students. They are useless in highlighting school performance.
