Doesn't that just imply that tests are failing to measure what we want teachers to teach and we should fix the tests ?
The whole reason that test results are being used as opposed to manual assesment, is that test results have proven to be a better predictor of long term outcomes. Test results aren't perfect but they're better than what was previously used.
"test results have proven to be a better predictor of long term outcomes"
i'm not sure what long term outcomes you're referring to and how they were measured, but if they're education related the measurement was probably more test results. Yes, test results are a good predictor of future test results.
