The relative contribution of undergraduate grade point average (UGPA) and the Law School Admission Test (LSAT) to predicting academic performance in each of three years of law school was investigated. The LSAT makes its greatest contribution in early years and UGPA in later years. (Author/BW)

A factor analysis of the Law School Admission Test (LSAT) battery was undertaken to gain a better understanding of the specific abilities which contribute to performance on the tests. To determine whether greater amounts of testing time should be allocated to groups of items defined by the factor analysis, a validity study was conducted. Existing…

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)

Since the Law School Admission Test (LSAT) was first administered, the sponsors of the test have carried out predictive validity studies to evaluate the effectiveness of the test and other predictors in determining first-year law school performance. This report presents a summary of correlation study results for the 1995 and 1996 study years. The…

This study was undertaken to evaluate the predictive validity of the Law School Admission Test (LSAT) earned under accommodated testing conditions. Of special interest was the validity of scores obtained by test takers who were accommodated under nonstandard time conditions (i.e., accommodations that included extra testing time). Separate…

Use of the Law School Admission Test (LSAT) and undergraduate grade point average for members of minority groups are examined in relationship to recent LSAT studies and related research on admissions tests and test bias. Traditional predictors of law school grades were found to be as accurate for minority as for majority persons. (JT)

Using predictive validity studies of the Law School Admissions Test (LSAT) and the undergraduate grade-point average (UGPA), this study examined the large variation in the magnitude of the validity coefficients across schools. LSAT standard deviation and correlation between LSAT and UGPA accounted for 58.5 percent of the variability. (Author/EGS)

Two statistical approaches for adjusting grades were tested on data obtained from four American law schools (642 students). Neither item response theory nor the general linear model yielded consistent improvements in the predictive validity of Law School Admission Test scores and undergraduate grades for three schools. (SLD)

Graphs and charts pertaining to testing in affirmative action are presented. Data concern the following: the predictive validity of College Board admissions tests using freshman grade point average as the criterion; validity coefficients of undergraduate grade point average (UGPA) alone, Law School Admission Test (LSAT) scores, and undergraduate…

A study evaluated the accuracy of Law School Admission Test (LSAT) scores in predicting student law school performance. Male and female scores and White, Black, or Hispanic scores were compared. Data were drawn from 1987 and 1988 graduating classes of five geographically diverse law schools. No significant differences between groups were found.…

Heckman's correction for regression in selected samples for predictive validity studies was applied to a large data file on 7,984 law school applicants. Data included ethnic group, sex, socioeconomic status, undergraduate degree, school, scores on the Law School Admission Test (LSAT), writing ability, undergraduate grade point average, and age.…

Thirty-four research reports and summaries of projects studying law school admission and the Law School Admission Test (LSAT) are presented. These research projects were supported by the Law School Admission Council between 1970 and 1974. A subject index and an author index for volume I, covering 1949-1969, and for this volume are also provided.…

Thirty-eight research reports and summaries of projects studying law school admission and the Law School Admission Test (LSAT) are presented. These research projects were supported by the Law School Admission Council between 1949 and 1969. A subject and an author index, for this and the following volume, covering 1970-1974, are also provided. The…

Research sponsored by the Law School Admission Council (LSAC) between 1949 and 1974 is summarized. For each of 72 research projects, the project title, investigator's name, LSAC report number, and a one-paragraph statement of purpose and summary are presented. The methodological procedure, results, conclusions, and recommendations are also…
