For years, colleges have used placement exams to determine whether to deem incoming students "college ready" or assign them to developmental education. But emerging information reveals the tests have little correlation to students' future success, casting doubt on their use even as the high stakes for students of taking remedial courses become clear. Educators are rethinking whether the tests are fair and wondering if their traditional use constitutes a barrier to college completion. "Where to Begin?" explores the various ways states and systems are grappling with new, sometimes confusing, information about placement exams as part of broader student success initiatives.
