Context: In 2014, the FAA changed a long-standing approach to air traffic control candidates that eliminated preferences based on training and experience at flight schools in favor of a personality test open to anyone irrespective of experience. The move was made to increase flight traffic controller racial diversity. Before the change, candidates who had completed coursework at participating colleges and universities could be "fast-tracked" for consideration. The agency eliminated that program and instead switched to an open system to the general public, with no need for any experience or even a college degree. Instead, applicants could take "a biographical questionnaire" that many applicants found baffling.
