In 1988 and 1989, the American Board of Anesthesiology (ABA) developed a knowledge-based standard for its written certification examination. In brief, 13 "judges" developed a construct of a "borderline candidate," i.e., a candidate who was neither ideal nor clearly failing but rather had sufficient knowledge to just pass. ⋯ This standard resulted in higher success rates among the actual examinees taking the ABA examination (84% in 1989 and 90% in 1990) than had the normative standard used previously (80%). The authors suggest that the process they describe permits development of a reproducible criterion for success that is based entirely on mastery of a relevant body of knowledge rather than on normative considerations.
