PROWL

The Personal Records Online Web Link (PROWL) is a secure web-based, self-service student records solution which the LMU and Law School Community uses to register for classes, access academic records, registration information, student accounts, and other University services. PROWL accounts are life-accounts and are never deactivated. Alumni and former students may request transcripts, view records, and maintain correct contact information after leaving LMU or the Law School.
