Statistical Adjustments of Law School Grade Point Averages
John W. Young
In this study, two statistical approaches for adjusting grades were tested on data obtained from four law schools. These approaches were previously validated using data on undergraduates but have not been used in a study of postgraduate performance. Neither method yielded consistent improvements in the predictive validity of LSAT scores and undergraduate grades. The single exception was for School D where a significant improvement in the correlation of test scores with law school grades was observed.
