In the first three semesters of law school, NIU College of Law students take a pair of two-semester required courses, Basic Legal Research and Legal Writing and Advocacy. The two courses employ coordinated, real-life exercises. In Basic Legal Research, students learn to use both print and computer-assisted legal research tools. Students analyze a factual situation in order to develop a legal research strategy and learn how to locate and use secondary sources, case law, statutory and legislative history material, and administrative regulations. In Legal Writing and Advocacy, students develop skills through a series of intensive writing exercises culminating in an oral argument.

In Introduction to Lawyering Skills, students learn skills and techniques essential to the pretrial phase of a civil or criminal lawsuit. The course involves simulated experiences, including role-playing and videotaping, to provide immediacy of experience and direct feedback.

Various clinical experiences are offered each semester at the Clinical Law Center on the DeKalb campus and the Zeke Giorgi Legal Clinic in Rockford, Illinois. In addition, in 2013 the College of Law began a clinical partnership with Hesed House and Aunt Martha's Health Center in Aurora, Illinois that focuses on the legal issues that may contribute to health problems in the area’s indigent population.

At these clinics, students represent clients under the direction of well-qualified supervising attorneys. The clinical courses each have a classroom component in addition to the practice experience. They are taught by members of the College of Law faculty in conjunction with the supervising attorneys. These classes bring academic and practical worlds together, addressing a range of issues students experience in their cases, from honing legal skills, to exploring issues of substantive law and procedure, to considering real-world issues of professional responsibility and ethics.

The NIU College of Law was founded as the Lewis University College of Law on November 2, 1974. Due to a lack of funding to meet ABA requirements, the Lewis University administration began looking for an institution to transfer the law school to. Administrators from both NIU and Lewis University initially met in 1978 to discuss the transfer of the law school from Lewis University to NIU. Although there had been talk for quite some time of establishing a law school at NIU there had yet to be any real progress made. NIU and Lewis University began working on a proposal to submit to the Illinois Board of Higher Education (IBHE) in 1979. The IBHE rejected the proposal necessitating legislative action.

Illinois Senators David C. Shapiro and Philip J. Rock introduced Senate Bill 719 on April 12, 1979, to the Illinois Senate. Senate Bill 719 provided the legislation necessary for the law school transfer of jurisdiction from Lewis University to NIU and funding to support the law school at NIU. After passing in the Illinois General Assembly, Senate Bill 719 was approved by Governor Thompson on June 26, 1979 and signed into law as Public Act 81–37 the next day. Effective August 1, 1979, Lewis University College of Law would become Northern Illinois University College of Law. In the Fall of 1982, after more than seven years in Glen Ellyn, the NIU College of Law moved into its newly remodeled space within Swen Parson Hall on NIU’s main campus in DeKalb, IL. On August 11, 1982, the American Bar Association gave full accreditation to the NIU College of Law. The College of Law was admitted to the American Association of Law Schools on January 22, 1985.

Notable members of the Illinois General Assembly who graduated from the NIU College of Law include Representative Steven Andersson and State Senators John Curran and Toi Hutchinson. Nancy Kaszak, a Democratic member of the Illinois House of Representatives from 1993–1997 is also an alumna.

Local politicians Alderman Howard Brookins, former Alderman Robert Fioretti and former Clerk James Laski all graduated from the College of Law, the latter two graduated together in the Class of 1978.
