The Diocese had its association with the Jesuits since 1540’s when the dedicated Spanish Missionary St. Francis Xavier (1506-1552), co-founder of the Society of Jesus set his foot on the soil of Kottar about 1500 years after the advent of St. Thomas in 52 A.D.

The nuns constructed a 91-metre (300 ft) long single block of building at Ramanputhur, in the vicinity of Nagercoil Town and started the school.

It began with the preparatory class and first form under the management of Bernard Gonsalvez, and with Antony Pereira, B.A., as the first headmaster.

From June 1959 Jesuits from Madurai province took charge and added the Higher Secondary School division.

Poor[weasel words] students are assisted by the waiving of school fees, a morning meal scheme, and works of charity in collaboration with the Carmel Alumni Association.

Cadets participate in the Republic Day March Past at Rajpath, New Delhi, and attend a variety of camps.
