The Long Island Business Institute (LIBI) began in 1968 as a business school in Commack, Long Island, and was certified as an occupational College in 1995 by the New York State Board of Regents. The Regents authorized LIBI to award the Associate in Occupational Studies (A.O.S.) degree in Court Reporting under the guidance of the Office of Higher Education of the New York State Education Department (NYSED). Since then, degree programs in Accounting, Business Management, Emergency Care Management, Homeland Security and Security Management, Hospitality Management, and Office Technology with Medical Office Option have been registered with NYSED, along with certificate programs in Court Reporting, Elder Care Administration, Hospitality Management, and English as a Second Language. Long Island Business Institute is a proprietary college accredited by the Accrediting Council for Independent Colleges and Schools (ACICS) to award certificates and associate degrees.
In 2001, LIBI opened a branch campus in Flushing, New York; and in 2008, it was re- designated as the main campus. As of 2013, LIBI Commack has approximately 120 enrolled students and LIBI Flushing has over 758 students. Average class size is small, allowing for attention to the needs of individual students. Convenient and flexible day and evening schedules meet the needs of adults with family and work obligations.
