Trustees of the Whittier Law School said on Wednesday that it would close down, making it the first fully accredited law school in the country to shut at a time when many law schools are struggling amid steep declines in enrollment and tuition income.

The trustees of the school, in Costa Mesa, Calif., said in a statement that they had voted not to enroll new first-year students in the fall but were “committed to ensuring that students currently enrolled will have an opportunity to complete their degree in a timely fashion.” The trustees did not set a date for when the school would close.

Marc Stevens, a spokesman for the school, which is affiliated with Whittier College, said that officials were exploring ways to allow nearly 400 current students to complete their education but had not yet arrived at a solution.

Whittier is the first law school fully accredited by the American Bar Association to announce plans to close. Indiana Tech Law School, in Fort Wayne, which had only provisional accreditation from the bar association, has announced that it will close in June.
