Guardian International School (GIS) is a secular, non-profit educational institution established in 2012 by the Guardian Foundation. Founded by three distinguished alumni of NIT Calicut—Paul N. Jacob (Mechanical Engineering), K. Vijayaraj (Electrical Engineering), and Sarto Rajendran (Civil Engineering)—the school was created with a vision to make quality education accessible to every child, regardless of their socio-economic background.

Located in Chengalpattu, a rapidly developing satellite city of Chennai, GIS offers the CBSE curriculum enriched with a global outlook and modern teaching methodologies. The school serves students from diverse cultural, social, and economic backgrounds, creating an inclusive learning environment that nurtures academic excellence, character development, creativity, and social responsibility.

At Guardian International School, we believe that every child possesses unique potential. Our mission is to empower students with the knowledge, skills, values, and confidence needed to thrive in an ever-changing world. Through a balanced blend of academics, technology, innovation, sports, arts, and life skills, we prepare students to become responsible global citizens and lifelong learners.

We strive to create meaningful educational experiences that inspire curiosity, foster critical thinking, and encourage students to build lasting friendships while enjoying a joyful and enriching school life.
