St. John's Higher Secondary School in Sithanangoor began its journey on June 3, 1991, under the visionary guidance of Sun. John Peter. Originally established as a High School, it was later upgraded to a High School on June 1, 1996. The school holds historical significance as it played a crucial role in providing high school education to girls from marginalized communities in the Sithanangoorarea. Arulpani initiated this noble endeavour, with the dedicated support of John Peter and his wife, Mrs. Francisca Sachamari, M.A., B.Ed.

Noteworthy Achievements:
Hostel facilities were initiated on June 3, 1991, for male students, and on June 1, 2010, for female students, demonstrating a commitment to the welfare of economically disadvantaged students.
