Two methods for estimating measures of pass-fail reliability are derived, by which both theta and kappa may be estimated from a single test administration. The methods require only a single test administration and are computationally simple. Both are based on the Spearman-Brown formula for estimating stepped-up reliability. The non-distributional…

Two methods--non-distributional and normal--are derived for estimating measures of pass-fail reliability. Both are based on the Spearman Brown formula and require only a single test administration. Results from a simulation (n=20,000 examinees) and a licensure examination (n=4,828 examinees) illustrate these methods. (SLD)

Peer reviewedHambleton, Ronald K.; Slater, Sharon C. – Applied Measurement in Education, 1997
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…
