SMALL SIZE, BIG OPPORTUNITY

Each student at ONU Law is a valued member of our tight-knit community, enjoying individual attention and small class sizes. They also benefit from unrivaled access to professional networks, experiential learning and life-changing opportunities.

ONU LAW AT A GLANCE

One of five colleges at Ohio Northern University, the Pettit College of Law enjoys a rich history and distinguished academic reputation.

  • 2nd Oldest law school in Ohio
  • 188 Students representing 95 undergraduate institutions
  • 20 Full-time law faculty
  • 5,423 Living Alumni
  • Founded in 1885, ONU Law is the second oldest of nine Ohio law schools. Throughout our long history, we’ve been affiliated with the United Methodist Church and have embraced church-related values. We welcome persons of all faiths to our community and provide a supportive environment for moral and spiritual growth.

  • ONU Law's mission is to provide an education that will allow students to become competent, ethical, and professional practitioners able to apply their skills and talents across a range of practice environments. The educational program is designed to provide students with a substantial opportunity to regularly interact with faculty, to gain professional skills, and to research a topic of personal interest within a critical yet collegial environment.

  • ONU Law has been fully accredited by the American Bar Association since 1948 and a member of the Association of American Law Schools since 1965. Fully accredited law schools are subject to comprehensive periodic site visits every ten years. Questions regarding accreditation may be directed to the Council of the Section of Legal Education and Admissions to the Bar, American Bar Association, 321 North Clark Street, 21st Floor, Chicago, IL 60654, 312-988-6738.

  • At ONU Law, we define our value by our community--professors are mentors, upperclassmen are coaches, and classmates are cheerleaders for each other. When students graduate, they become part of a dedicated and loyal ONU Law alumni network that spans all 50 states and abroad.

  • Our innovative curriculum emphasizes practical training, academic support, and bar exam preparation. As a result, our students experience incredible success on the bar exam, oftentimes ranking in the top three in the state for first-time pass rates and securing rates consistently above the national averages. We also pack a mighty punch when it comes to job placement, again placing above both state and national averages.
