ABSTRACT
This chapter discusses some challenges common to competitive sport measurement, and considers additional challenges specific to several competitive sport contexts, including coaching, athletic training, hunting and fishing, and multisport competition. It focuses on testing for illicit substances in athletic and employment settings. Measuring qualitatively is more challenging. Diving, gymnastics, figure skating, and other similar sports require officials to possess high levels of expertise. Teachers of physical and motor skills, athletic trainers, and physical therapists also engage in a form of coaching. Teachers don't have to select teams, but they do have to assess and motivate their students. Professional sports organizations, such as those for baseball, basketball, soccer, and American football, are very interested in measuring potential players. The measurement of multisport competitions presents perhaps the greatest measurement challenge in sports. One of the best-known technological changes in sport is the instant replay.
