Dr. Robert J. Gee, whose lavish spending and fiscal stewardship at the Falmouth-based National Graduate School of Quality Management have spawned three separate inquiries, has been removed as the college’s president by the board of trustees, the school informed its staff yesterday.

Thomas C. Kneaval, the chairman of the school’s board of trustees, said in an e-mail that Gee would return to teaching and “other activities related to” a hastily scheduled review by the New England Association of Schools and Colleges, which accredits institutions of higher education. The association’s next review had been scheduled for 2014, but was recently moved up to September because of revelations about the school.
