Among the few replicable findings from research on higher education, one of the most notable is that student evaluations of teaching are both useless as measures of the extent to which students have learned anything and systematically biased against women and people of color. As this story says, reliance on these measures could lead to lawsuits.
But why hasn’t this already happened. The facts have been known for years, and potential cases arise every time these evaluations are used in hiring or promotion: arguably every time the data is collected. And student evaluations are particularly popular in the US, where litigation is the national sport. Yet no lawsuits have yet taken place AFAICT.
Maybe the zeitgeist is changing. I was going to write this post before seeing the linked article, which turned up in my Google search. Any lawyers or potential litigants want to comment?
