Preceeding through the development of a sequence of paired calibrations determined by a hierarchical clustering algorithm, the proposed method of constructing a universal criterion scale does not rely on covariate information. The procedure is illustrated with data from American law schools. (Author/BW)

A universal criterion scale is applied to the direct estimation of validity for various groups of law school applicants and to the testing of the assumptions underlying the more familiar extrapolation methods. Data from American law schools are used to illustrate the procedures. (Author/BW)
