An approach is presented to the definition of minimal competence for judges to use in standard setting. Panelists in standard setting must receive training to ensure that differences in rating result from differences in perceptions of item difficulty, not in differences of opinion about the definition of minimal competence. (SLD)

Training judges to generate item ratings in standard setting once the reference group has been defined is discussed. It is proposed that sensitivity to the factors that determine difficulty can be improved through training. Three criteria for determining when training is sufficient are offered. (SLD)
