This is a cliché by now, but the public schools where I live are producing test-takers: pretty good ones, as far as the numbers show. At parent night at the beginning of the school year, we were introduced to a curricular program explicitly built around “assessments”—the new euphemism, I gather; maybe it intimidates less. A new study now purports to show that testing doesn’t enhance cognition. I’m not sure it was supposed to, but in any event, the critique is that teaching to the test fails to improve learning outcomes. I’m inclined—warning: this is anecdotal—to believe it does improve them, but toward the bottom, where massive investments are being made. What we may be losing in the bargain is what these tests don’t capture: excellence at the top. Welcome to Tocqueville’s democratic equality.
