The Student Handbook will explain LL.M. program guidelines, the LL.M. curriculum, the grading scheme, and other information that will be useful to you after you enroll. Reading the Student Handbook will help you, as an LL.M. applicant and LL.M. student, develop reasonable expectations about the LL.M. program.

Check with the admissions office of LL.M. programs that interest you, and ask for a copy of their Student Handbook. If the LL.M. program that interests you does not have a Student Handbook, or if that program is unwilling to share their Student Handbook with you, then you might consider choosing a different U.S. law school for your LL.M. degree.
