Accreditation is a critical process in maintaining standards of consistency and excellence in the academic preparation of students for their chosen profession. While academic programs, professional associations, and credentialing organizations all recognize the importance of programmatic accreditation in recreational therapy professional…

California's Commission on Teacher Credentialing (Commission) requires all programs of preliminary multiple and single subject teacher preparation to use a Commission-approved Teaching Performance Assessment (TPA) as one of the program completion requirements for prospective teacher candidates. Three TPA models were approved by the Commission: (1)…

One common modification to the Angoff standard-setting method is to have panelists round their ratings to the nearest 0.05 or 0.10 instead of 0.01. Several reasons have been offered as to why it may make sense to have panelists round their ratings to the nearest 0.05 or 0.10. In this article, we examine one reason that has been suggested, which is…

This article discusses regression effects that are commonly observed in Angoff ratings where panelists tend to think that hard items are easier than they are and easy items are more difficult than they are in comparison to estimated item difficulties. Analyses of data from two credentialing exams illustrate these regression effects and the…

Numerous studies have compared the Angoff standard-setting procedure to other standard-setting methods, but relatively few studies have evaluated the procedure based on internal criteria. This study uses a generalizability theory framework to evaluate the stability of the estimated cut score. To provide a measure of internal consistency, this…

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)
