There might be a really strong correlation, but the deviations from that correlation might not be totally random. That is, there might be people who consistently test above or below their skill level. This creates some weird imbalances that are far from fair.

It would be a lot more acceptable if deviation of test scores from skill were to be totally random for every test.

I can understand biases in a specific test (e.g. cultural biases), but those can (and should!) be corrected with better design and specific accommodations. Do you think that testing as a general method of evaluation is biased though? Because the objection I typically see isn't "we need better test design" it's "there's a component of student ability that cannot be measured by a test".

  • It is more about things like stressing over tests, dyslexia, ability to sit still for x hours and ability to express yourself in writing.

    These all affect how well you test, but do not determine your skill in the subject. Hence, having a disadvantage in any of the above gives you a system disadvantage in the educational system.
