The school had extensive boarding facilities and attracted many sons of the wealthiest Catholic families in the northeastern United States. It also attracted a strong international contingent, particularly from Latin America. For many years LSMA was considered one of the top preparatory schools on the East Coast. It was accredited by the Middle States Association of Colleges and Schools. Its academics were held in the highest regard and although LSMA did not require its students to take Regents Examinations, they never found this to be an issue. LSMA's reputation was such that its graduates were consistently admitted to the best colleges. Graduating classes were often 100% college-bound.
