Law schools, in the face of marked declines in enrollment, revenue and jobs for graduates, are beginning to adopt innovative new ways of delivering legal education.

Some law schools are moving away from relying solely on classic settings and instead are blending classroom learning with online instruction, said Michael B. Horn, a founder of the Clayton Christensen Institute, a research institution in San Mateo, Calif., that explores disruptive innovation in education.

“Legal education is confronting the most imminent threat in higher education,” Mr. Horn said. “Law schools are increasingly out of step with shifts in the legal services market.”

Law schools that “are able to pioneer online, competency-based programs that focus outside of the traditional J.D. will have a leg up in the struggle to survive,” said Mr. Horn, an author of the newly released report, “Disrupting Law School: How Disruptive Innovation Will Revolutionize the Legal World.”
