Not everything can be quantified, and I think it's a dangerous line of thinking to equate impact with measurability. Particularly in education, the focus on standardized testing has had real negative impact in the fuzzier areas like critical thinking and the joy of learning. Of course I can't quantify this, but that doesn't mean it's not true.

I get that standardized tests are necessary to some extent, but I would not equate the things that led me to do well on them as the most impactful events of my education. One-on-one human interaction and empathy has been what elevated me past the hoop-jumping to a higher level of agency and self-motivated productivity.
