The ST. JOHN THE BAPTIST HIGH SCHOOL and JR.COLLEGE, THANE is affiliated to the Mumbai Division Board of Secondary and Higher Education. It is situated in Thane town of Thane District. It was started as Primary School in 1905. We had the school recongised by the Education Department as an English Teaching High School in 1938.

St. John the Baptist high School is a Christian School/College established and administered by the Roman Catholic Archdiocese of Mumbai. The School/College is under the religious jurisdiction of the Roman Catholic Bishop of Mumbai. It is affiliated to the Catholic Archdiocesan Board of Education.

The School/College aims at the education primarily of the Catholic community around and to the extent possible of the members of all the communities. The School/College stands for academic excellence, development of skills, and character formation based on the love of God and service of as modelled in Jesus Christ, with a view to training citizens distinguished for their all round development and commitment to God and Country.

At the insistent request of the Educational Department, a Junior College has been attached to the High School from June 1979.

We opened Science and Commerce classes of the Junior College in the academic year 1979 - 80 on the insistent request from the Department of Education, Thane. The Education department being fully aware of the congenial atmosphere prevailing in St. John Campus and the quality of instruction imparted here, had made this proposal to us.

As a matter of course, in the academic year 1980 - 81 S.Y.J.C. Science and Commerce classes were opened.
