If the students didn't perform, but her superiors liked her, why are you assuming the superiors know what they are talking about?
Again, how can I compare the opinions of heterogeneous superiors, and why do you believe the opinions are correct and objective metrics are wrong?
Opinions fail on many counts - comparability and objectivity being the most obvious. Why do you fetishize opinion, and assert it as being more accurate than objective metrics?
They also shouldn't dominate what's taught to the extent they do.
All standardized tests do is measure whether a school is meeting their goals. If standardized tests are preventing schools from ignoring their goals and teaching whatever they feel like (or perhaps nothing at all), why is that a bad thing?
Further, standardized tests don't really measure much, except for how well student can take tests and regurgitate information.
Metrics are fine, they just shouldn't be fetishized, and we shouldn't allow them to make us fire good teachers. They also shouldn't dominate what's taught to the extent they do. Nation of multiple choice test-takers? That's what we want out of our school system?
