Specific steps for applying the Angoff method are described. In the Angoff method, judges are asked to estimate the probabilities of minimally competent candidates' answering multiple choice test items correctly. Initial information must be obtained for designing the standard-setting process, beginning with the purpose of the examination and any…

Three studies assessed the psychometric characteristics of the Direct Standard Setting Method (DSSM). The Angoff technique was also used in each study. The DSSM requires judges to consider an examination 10 items at a time and determine the minimum items in that set a candidate should answer correctly to receive the credential. Nine judges set a…

Credentialing programs were surveyed to determine the procedures they use to set performance standards on multiple-choice and open-ended assessments. Implications of the various standard-setting approaches for the National Assessment of Educational Progress are discussed, and it is asserted that generalizing from standard-setting in professional…

The major forms of evidence that support a standard's credibility are reviewed, and what can be done over time and for different forms of an examination to enhance its comparability in a credentialing setting is outlined. Pass-fail decisions must be consistent to ensure a standard's credibility. (SLD)

Two new indices of stability of content-referenced standard-setting results are presented, relating variability of judges' decisions to the variability of candidate scores and to the reliability of the test. These indices are used to indicate whether scores resulting from a standard-setting study are of sufficient precision. (Author/LMO)

A brief history of developments in the assessment of the reliability of credentialing examinations is presented, and some new results are outlined that highlight the interactions among scoring, standard setting, and the reliability and validity of pass-fail decisions. Decision consistency is an important concept in evaluating credentialing…

Technical advances of the last 15 years in measurement theory and practice are described, notably criterion-referenced testing, item response theory, and computers and testing. Several remaining problems concerning the development and validation of credentialing examinations are also considered. (Author/LMO)

Career-technical educators face three issues in credentialing through assessment. First, the occupational credentialing domain is large and evolving, and a clear understanding of it is a prerequisite to considering adoption of a credential. Three types of credentialing are registration, certification, and licensure. Credentialing organizations are…
