Educational activities of the Nirmala Charitable Trust was started in the year 1956 with functioning of a primary school at Thalacode in Chottanikkara panchayat, which was a very undeveloped locality at that time.

The founder of the trust Very Rev. O.C. Kuriakose Kor-Episca was a great visionary.  He wanted to have pre-primary to higher education institutions under the Trust.

The school was soon upgraded to Upper Primary and High School with parallel English Medium divisions.  English medium schools were rare those days.  Hence, students from faraway places also joined the school.  Boarding facility for students was provided at thalacode since 1965.  In the year 1967 first batch of SSLC passed out from the school.  St. Mary’s High School Thalacode was one of the 15 schools securing 100% pass in SSLC in the state.

Very Rev. O.C. Kuriakose, who was also the Headmaster of the school, was honoured with best teacher award by Government of Kerala. On February 2, 1993, V.Rev.O.C. Kuriakose Cor-Episcopa entered his heavenly abode.

The Trust continued its educational activities with great vigor as per the wishes of the founder who is the leading light in all our endures.  In 1998, a higher secondary school was sanctioned at Thalacode.
