The sisters of the Congregation of the Mother of Carmel entered the field of university education in 1946 with the inception of St. Mary's College, Thrissur. It is the pioneer First Grade women's college in the district. It soon grew into a full-fledged First Grade college with two postgraduate courses in economics and English literature. In 1967, St. Mary's was bifurcated, the pre-degree section remaining in Thrissur and the undergraduate and postgraduate sections being shifted to Vimala College, Cheroor. In 1979 St. Mary's once again regained its status as a First Grade college with the starting of B.A., B.Sc. courses. Postgraduate courses in mathematics and history were introduced in 1995 and 1998 respectively.

After the trifurcation in 1987, St. Mary's and Vimala Colleges were still under the CMC Educational Society, Thrissur, which have a creditable history in the field of education.
