Is it possible to measure creativity? Is it possible to measure artistic talent? Is it possible to assign a grade to students in the arts based on a measure or on multiple measures?

Those are the questions posed in this article, which describes the efforts by states to develop metrics for the arts. https://m.artsy.net/article/artsy-editorial-forget-the-sat-this-new-standardized-test-measures-artistic-ability

I am assuming that the title of the article is a mistake. It is not about a “standardized test” for the arts but rather a replacement for standardized tests.

I instinctively recoil at the idea of measuring creativity or artistic talent. There is something inherently subjective about any such judgments. These days, who can say what is art and what is not.

Please, teachers of the arts, help me here. I can see grading students for participation, persistence, and engagement. But how can you grade them for talent and creativity?
