The contributions made by the Carmelites of Mary Immaculate (CMI), the first indigenous Catholic Congregation of India, in the educational field of Kerala were pioneering and revolutionary. Blessed Kuriakose Elias Chavara, the founder of the CMI Congregation, founded the first Catholic School of Kerala at Mannanam, near Kottayam in1846. Gradually all the other CMI Monasteries also followed the movement. In the year 1864, Blessed Chavara, in his capacity as the Vicar General of the Syro - Malabar Church, Vide his Vicarial Orders urged all the parishes to start schools adjacent to their Churches. This historic order triggered the emergence of a galaxy of educational institutions all over the State. This Movement later on formed the basis of the social-economic development of the whole State.
The main aim of the entire educational endeavor of the Congregation is to bring about a social transformation with an option of manifold opportunities for the poor, coupled with an emphasis on moral reconstruction of the society as a whole. Today, the CMI Congregation runs about 449 educational institutions which include a Deemed University, Arts and Science Colleges, Autonomous Colleges, M. Ed and B. Ed Colleges, Engineering Colleges, Polytechnic Colleges, Schools, ITC Centres, Nursing Schools, Research Centres and a Medical College.
