Four purposes of this talk are: 1) to describe the origin and purpose of the Educational Testing Service; 2) to give an idea of the extreme care to which ETS goes in preparing the materials which become part of the Law School Admission Test (LSAT); 3) to illustrate how good the tests are; and 4) to discuss some suggestions for the most effective use of the LSAT score. The thesis of the talk is that "the tests, properly used along with pre-law grades and with the other criteria... do a far better selection job than we know how to do in any other way." Two charts are also included to illustrate this last point. One shows the effective prediction of scholastic success in law school, as shown by pre-law grades alone and by the 1948 LSAT and pre-law grades combined. The other shows "sample ABAC", a graph for predicting first- year law grades from LSAT test scores (x-axis) and pre-law grades (y-axis).
