This research compared the cut-off scores estimated from an empirical procedure (Contrasting group method) to those determined from a more theoretical process (Nedelsky method). A methodological and statistical framework was also provided for analysis of the data to obtain the most appropriate standard using the empirical procedure. Data were provided from New Jersey's Minimum Basic Skills tests in reading and mathematics, administered in grades 3, 6, 9, and 11. (Tables show the degree of consistency between the proficiency standards estimated using the two procedures. Further, a modification of the linear discriminant function and the quadratic discriminant function, developed by Conover and Iman, is proposed as an appropriate method of analysis for the contrasting groups procedure).
