The LSAT is a half-day standardized test required for admission to all 197 LSAC-member schools. It provides a standard measure of acquired reading and verbal reasoning skills that law schools can use as one of several factors in assessing applicants. The test consists of five 35-minute sections of multiple-choice questions. Four of the five sections contribute to the test takers' score. These sections include one reading comprehension section, one analytical reasoning section, and two logical reasoning sections. A fifth section typically is used to pretest new test items and to preequate new test forms. A 30-minute writing sample is administered at the end of the test. The score scale for the LSAT is 120 to 180. The test is designed to measure skills that are considered essential for success in law school.
