Tucked into the hills of Rajamudi in Idukki district, De Paul Public School was established in 1998 by the De Paul Trust under the auspices of St. Joseph's Province of the Vincentian Congregation - a Catholic Christian minority institution that carries the motto "For God and Country." Affiliated with the Central Board of Secondary Education, New Delhi since the year 2000, the school operates at the primary, secondary, and senior secondary levels, drawing its founding spirit from St. Vincent de Paul, the 17th-century patron whose legacy of charitable service continues to shape the institution's ethos. As a Christian minority school, De Paul is constitutionally entitled under Article 30 and primarily aims at meeting the educational requirements of the Catholic community in the Idukki region, while remaining open to all students seeking quality English-medium education.

Being a CBSE school in Idukki with over two decades of board examination results, De Paul Public School has built a proven track record at both the Class 10 and Class 12 levels. The school follows a curriculum that places equal weight on skills, knowledge, and values — preparing students to function as capable adults in a rapidly changing world. The school also functions as a Junior College, extending its academic reach beyond the school years for students in this part of Kerala's high-range district.

The campus at Rajamudi is set in a serene natural environment, with a Physics laboratory, a Computer lab, and a school bus facility covering transportation for students across the area. The infrastructure is described on the school's website as hi-tech, and the learning environment is structured to be child-friendly. The Vincentian Congregation's influence is visible in the school's emphasis on compassion, integrity, and community participation alongside academic preparation.
