Testing - What Does it Reveal?
Psychology Today put forth this article by researcher Susan Engel, "What Test Scores Don't Tell Us: The Naked Emperor." Ms Engel reviewed over 200(!) studies of K-12 standardized tests. What I have discovered is startling- most tests used to evaluate students, teachers, and school districts predict almost nothing except similar scores on subsequent tests. I have found virtually no research demonstrating a relationship between those tests and measures of thinking on the one hand, or life outcomes on the other. To grasp what we do and do not (yet) know about standardized tests, it’s worth considering a few essential puzzles: why we find individual differences in test scores (why one child does better or worse than others), what makes a child’s test scores go up, and what such improvement could possibly indicate.
