    Errors of measurement and standard setting in mastery testing
    (1984) Kane, Michael T.; Wilson, Jennifer
    A number of studies have estimated the dependability of domain-referenced mastery tests for a fixed cutoff score. Other studies have estimated the dependability of judgments about the cutoff score. Each of these two types of dependability introduces error. Brennan and Lockwood (1980) analyzed the two kinds of errors together but assumed that the two sources of error were uncorrelated. This paper extends that analysis of the total error in estimates of the difference between the domain score and the cutoff score to allow for covariance between the two types of error.
