Factors in Performance on the Law School Admission Test. Statistical Report. LSAC Research Report Series.
Wilson, Kenneth M.; Powers, Donald E.
This study was undertaken to clarify the internal structure of the Law School Admission Test (LSAT) and shed light on the ability or abilities measured by the three item types that make up the test (logical reasoning, analytical reasoning, and reading comprehension). The study used data for two forms of the LSAT for general samples of LSAT examinees and a subsample of LSAT examinees identified as also having taken the Graduate Record Examination (GRE) General Test, which includes the three item types that make up the LSAT. Within the joint LSAT/GRE sample, it was possible to conduct separate, parallel factor analysis of the parcels of item types common to both tests, assess time-related effects on between-test correlations, and analyze factor structure underlying performance on combined LSAT and GRE parcels of logical reasoning, analytical reasoning, and reading comprehension items. Unique features of the study were the use of data from both the LSAT and GRE General Test to assess structure in item types common to both tests and the method of pooling different items of the same type and position across multiple test forms in order to create parcels used to generate correlations for analysis. Study findings suggest a similar structure for logical reasoning, analytical reasoning, and reading comprehension item types regardless of the test in which they are used. The structure entails two dimensions, one involving aspects of general reasoning as measured by logical reasoning and reading comprehension item types, and the other more narrowly constrained, formal-deductive aspects of reasoning tapped by the analytical reasoning item type.
