LSAC and the LSAT: A Proven Track Record of Supporting Legal Education About the LSAT® The Law School Admission Test® (LSAT) is developed and administered by LSAC, a not-for-profit organization whose mission is to advance law and justice by promoting access, equity, and fairness in law school admission and supporting the learning journey from prelaw through practice. LSAC has served as a trusted partner to law schools in inclusive excellence and evidence-based innovation for 75 years, providing the LSAT and other legal education products and services. Demonstrated to be fair, valid, and reliable, the LSAT measures the reasoning, reading, and writing skills that are essential for success in law school and the legal profession. The LSAT is designed specifically for law school admission. As part of a holistic admission process, the LSAT provides a way for schools to identify highly qualified candidates who might be overlooked on the basis of undergraduate institution, GPA, lack of access to extracurricular activities, or other factors. Research consistently shows the LSAT is the best single predictor of law school success, even better than undergraduate GPA. Similarly, research consistently shows that the combination of the LSAT and undergraduate GPA provides the strongest prediction of law school success, as an invaluable component of a holistic admission process. LSAC conducts correlation studies and other research for individual schools on how LSAT scoresand other applicant credentials correlate to student performance at their schools. Schools have a long history of using the LSAT and know how to use the test and other predictors in their holistic admission process. LSAC is far more than just the LSAT. LSAC’s single focus is legal education, so all of LSAC’s energy and resources are devoted to expanding and diversifying the pool of law school candidates and programs to support students and schools.

[LSAC.org](LSAC.org) LSAT Format The LSAT consists of four 35-minute sections of multiple-choice questions and an unscored writing section. The multiple-choice sections measure the ability to think critically, analyze and evaluate the reasoning and arguments of others, and read complex texts with understanding and insight. Three of the multiple-choice sections are scored, while one section is unscored and used to evaluate new test questions and ensure they are free from any form of bias. LSAT Argumentative Writing is administered separately from the multiple-choice portion of the test. Copies of test takers’ writing samples are sent to all law schools to which they apply. Test Validity Because the LSAT is designed to accurately measure the skills that are critical to success in law school (construct validity) and it predicts first-year law school performance more accurately than any other single factor (predictive validity), the LSAT is a valuable tool for admission professionals to use in crafting their successful incoming classes, as part of their holistic admission process. Test validity can be defined as the extent to which a test accurately measures what it is meant to measure. Validity is made up of a number of different components, but two of the key components of validity for the purposes of law school admission are construct validity and predictive validity. Construct validity consists of measuring the right skills in the right way. In other words, a test has construct validity with respect to law school admission if it measures skills that are directly necessary for success in law school, and if it measures those skills accurately and effectively. The LSAT was designed specifically for this purpose, and it is constantly revalidated for this purpose. Predictive validity refers to the extent to which a test accurately predicts the relevant outcome. LSAC conducts large-scale studies of the LSAT’s
