It is easy to register for the LSAT online at www.lsac.org. This is the website of the Law School Admission Council, which administers the LSAT.
There is a US$120 registration fee to take the LSAT. For late registrants, an additional US$60 late fee is added.
In addition, almost all ABA-approved US law schools will require you to register with the Law School Data Assembly Service (LSDAS). The LSDAS, or Law Services, prepares and provides a report for each law school to which you apply. This report contains information that schools use, along with your application, personal essay, and letters of recommendation, to make a decision on your application. Once a law school creates a file for you, they will request your information from Law Services. The LSDAS report includes an undergraduate academic summary, copies of all undergraduate, graduate, and law school/professional school transcripts, LSAT scores and writing sample copies, and copies of letters of recommendation processed by Law Services through their recommender service.
LSDAS charges a $109 fee for the service. Your LSDAS period extends for 5 years from your registration date. This subscription includes law school report preparation, letter of recommendation and transcript processing, and access to electronic application for all ABA-approved law schools. Law school reports are available for $12 each before or after you register for the LSAT. You don't have to subscribe to LSDAS when you register for the LSAT, but you should subscribe as soon as possible before your first law school application deadline.
