Law School Admissions Test (LSAT) EXAM SITEThe LSAT is an integral part of law school admission. The purpose of the LSAT is to test the skills necessary for success in the first year of law school. Those skills include reading comprehension, reasoning, and writing, and the test results help admission decision makers and candidates alike gain valuable insight as to law school readiness. Studies have consistently shown the LSAT to be the single best predictor of first-year law school performance, even better than undergraduate grade-point average.
