In addition to labeling kids who learn differently as problematic, sometimes defective, most schools classify, track, and categorize students from very early ages. As an abundance of research studies confirm, these classifications tend to become self-perpetuating and self-confirming. My interviewees illuminate the ways in which grades, tests, and opportunities to learn are often arbitrary or related to class, race, and gender. In the supposed meritocracy of schooling, these markers and estimations have profound impact, not just structuring how we fit into the learning hierarchy of an individual classroom, but who we are who whom we believe we will become.
