Yes, the LSAT is available in Spanish, but only to test takers that plan to take the exam in Puerto Rico and are applying to one of the three ABA-accredited law schools in Puerto Rico. Test takers in locations outside of Puerto Rico will not be able to take the Spanish LSAT.
Scores from the Spanish-language version of the test can then be reported to three Puerto Rico law schools. These include Inter American University School of Law, Pontifical Catholic University of Puerto Rico School of Law, and University of Puerto Rico School of Law. Those schools will continue to accept the scores of the English version of the LSAT as well. LSAC will not release scores to schools outside of Puerto Rico. These results are only usable only for the three Puerto Rico law schools.
The one other point of note: the Spanish LSAT has a different scoring scale than the English version of the LSAT.
