What information does the Board of Examiners consider when making decisions about passing scores?
The Board of Examiners (BOE) considers: ” Descriptive statistics for each examination item and the overall examination (number of candidates, mean, median, standard deviation). ” Correlations between each exam item (i.e., station) and total exam score. The correlation coefficients indicate the extent to which a station is contributing useful information to the overall score. Correlation coefficients theoretically range from -1.0 to +1.0. The BOE considers a correlation coefficient of +0.20 or higher as acceptable (i.e., contributing useful information to the total score). ” Reliability and reproducibility coefficients. ” A comparison of the degree of difficulty estimates (Angoff estimates) for each station with the actual performance (mean score) for that station; ” Trends in mean station scores for repeated stations (i.e., mean scores for stations used on this administration compared to previous uses of the same stations). This information helps to determine the consistency of candida
