On the 30th October 1834, an Act for the sale of the real estate of Robert Hugh Munro and Caleb Dickenson was read and passed on November 6. By this Act, the Trustees were given the power of sale of the real estate and slaves of Robert Hugh Munro and Caleb Dickenson for investing the funds and applying the same to the purposes of their wills and for no other purpose.
The Trustees were appointed to select a convenient and healthy site or sites within the former limits of St. Elizabeth for the erection of a school or several schools for poor boys and a school or several schools for poor girls and for an Alms House.
In 1856, a Free School for boys was opened near Black River and early in 1857, the premises of Potsdam in Santa Cruz Mountains were purchased and the school removed there. The girl's school was first opened at Mount Zion in 1874 and on the 1st January 1885, was removed to Malvern House and then to Hampton.
By-Law 34 of 1879, the Jamaican Schools Commission was empowered to make schemes for the management of secondary schools. The Munro and Dickenson School came into operation on 1st January 1891. This was amended in February 1903. The existing Trust was removed and the future Trust was made of the Custos and the Chairman of the Parochial Board of St. Elizabeth and Manchester and five persons appointed by the Governor.
Throughout its history, Munro College has produced generations of leaders, scholars, and professionals who have contributed significantly to Jamaica and the world. The school continues to uphold its tradition of excellence while embracing modern educational methods and technology.
