During the LSAT registration process, you will be required to upload a photograph to your LSAC.org account. The photo will be inserted on your admission ticket, which you must print out and bring with you in order to gain admission to the test center. Admission tickets that do not display an uploaded photo will not be accepted on test day. Once your photo has been uploaded, it may be reused for future tests, and for test date or center changes.
In addition to the admission ticket, you must produce a valid government-issued ID in order to gain admission to the test center.
