But it’s worth quickly discussing the fact that such criticism is conditional on how the ratings are employed – there is a difference between the use of testing data to rate schools for parents versus for high-stakes accountability purposes.
In other words, the utility and proper interpretation of data vary by context, and there’s no one “correct way” to
