It seems like you're not at all understanding what I've been saying. The measure of teacher performance was based on student improvement over time on standardized tests. It is incredibly valuable to measure a teacher's capability in actually helping students learn and improve. After all, isn't that the sole purpose of teaching?
> That's because I didn't understand what your argument was. The usual argument is "teachers unions mean teachers are bad at their jobs so we can't trust their judgement and GPA. Instead, we need to look to standardized tests." That's the argument I thought you were making.
Yes, and we've also gone pretty far off-topic from what I was originally talking about at this point.
> No, it doesn't. It does give the citation:
Then why not lead with that citation and not the very weak conference paper that you chose to lead with?
"In an extended version of their essay, Kuncel and Sackett acknowledge that GPA is the best predictor of student success, but they add: “Even better prediction is obtained by the combination of test scores and high school grade point average.” “Human behavior is notoriously difficult to forecast,” they write, “it would be strange for a single predictor to be the only one that matters. So it is also valuable to consider, whenever possible, how predictors combine in foretelling student success.”
"Although the test-optional movement has received ample attention, its claims have rarely been subjected to empirical scrutiny. This volume provides a much-needed evaluation of the use and value of standardized admissions tests in an era of widespread grade inflation. It will be of great value to those seeking to strike the proper balance between uniformity and fairness in higher education."
One person is quoted as pointing out that an advantage using the SAT is that it can help combat grade inflation because it looks bad to have a really high GPA but really low SAT score. It's also been shown over time that the average GPA keeps going up while SAT scores are flat or declining. Grade inflation is a major problem, and the use of standardized test does help with it.

Anyways, you may be right about GPA currently being a better predictor of academic success than the ACT. But, as this article explains: https://www.jamesgmartin.center/2020/02/gpa-or-sat-two-measu...

If I were to further research this subject, I'd probably start with this book: https://www.amazon.com/Measuring-Success-Testing-College-Adm...
