Setting standards for the purpose of certification is frequently performed using judgmental techniques such as the Angoff method. This study was performed to identify types of items that judges find hard to rate accurately, that is, types of items on which examinees perform differently than predicted by the judges. Once identified these item types…

The influence of judges' knowledge on standard setting for competency tests was studied with 17 judges who took an economics teacher certification test while setting competency standards using the Angoff procedure. Judges tended to set higher standards for items they answered correctly and lower standards for items they answered incorrectly. (SLD)

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)

Studies of the Angoff method of standard setting suggest that judges agree in their estimates of the relative difficulties of test questions for minimally competent examinees and that each judge's estimates correlate well with the observed item difficulties for examinees whose total test scores are near the judge's personal standard (G. E.…

The effects of feedback about the ratings of other judges on subsequent ratings using the Nedelsky method and the ability of judges to retain or eliminate options in a manner consistent with the judgments of minimally competent examinees were studied using data from a basic algebra examination administered to 227 college students in 1987. The…

The impact of overall test length and difficulty on the expert judgments of item performance by the Nedelsky method were studied. Five university-level instructors predicting the performance of minimally competent candidates on a mathematics examination were fairly consistent in their assessments regardless of length or difficulty of the test.…

Minimum competency cut-off scores on a statistics exam were estimated under four conditions: the Angoff judging method with item data (n=20), and without data available (n=19); and the Modified Angoff method with (n=19), and without (n=19) item data available to judges. The Angoff method required free response percentage estimates (0-100) percent,…

Criteria for the selection of judges (evaluators) for setting item-based standards involved in tests for which cutting scores must be established are investigated. Focus is on cases in which test standards are based on specialists' judgments concerning the difficulty of test items in tests used to determine who will be awarded a diploma, admitted…
