Schools across the nation still essentially close to conduct inventory—only we don’t call it that. We call it “testing.” Every year at a given time, regular instruction stops. Teachers enter something called “test prep” mode; it lasts for weeks leading up to the big assessment. Just as grocery-store workers might try to fudge inventory numbers to conceal shortfalls in cash, schools sometimes try to fudge their testing results, and cheating scandals erupt. Then, in a twist, regular classroom instruction resumes only half heartedly once the big test is over, because there are no stakes attached to what everyone’s learning. Learning stops, evaluation begins: that’s how it works. But in the not-so-distant future, testing may be as much a thing of the past for educators as the counting of cans is for grocers.
