Another problem with relying on GPA is it is easily gamed. Parents and students can pressure teachers and administrations since so much is reliant on it. And a 4.0 at one school may not be the same at another school.

I understand some people "test poorly" but the truth is, if you actually know the material well, you'll test just fine in most cases. We can also coach students on how to approach testing. Other ideas are to break the test into various sessions with different admins to limit cheating potential and to take an average of the scores (or some other method) for each subject.

I guess my point is - make test results the metric to remove all bias. Change how we approach testing and preparation.

It doesn't remove all bias. It does remove a lot of bias and concentrates the remaining bias in a particular dimension, which probably does substantially improve the fairness of the system, but we need to be clear-eyed that it's not eradicating bias.
