In those formative years, the college offered courses for the award of the Teachers Certificate (TC) and The Teachers Advanced Certificate (TAC).
Witnessing remarkable developments in fulfilling its mandate of have been the premier institution for training teachers for the lower forms of secondary schools in the nation. The college attracted funding from UNESCO to upgrade its programs to the Higher Teachers Certificate and the college was renamed the Milton Margai Teachers College.
Over the past several decades, the Milton Margai Teachers College had experienced remarkable institutional transformation and renewal, growing from an institution training teachers for primary and lower forms of secondary schools into a leading tertiary –level Polytechnic known as the Milton Margai College of Education and Technology (MMCET), a merger of three formerly independent institutions; Milton Margay college of Education, the Technical Institute and Hotel and Tourism Training Institute. The new institution now offers degree programmes in Education, Social Science, Environmental Sciences, Business Studies, and Engineering.
Since the establishment of a polytechnic in 2001, the institution has provided services in training the lower and middle-level manpower, increasing the knowledge base and hence contributing to the development of the human capacity of the nation.
