A Foundation of Excellence

Cornerstone has been guided by its motto, “Encourage, Equip, Excel.” It is not just a school but a sanctuary of learning, where curiosity is nurtured, creativity is celebrated, and character is shaped.
Cornerstone’s academic excellence is evidenced by its consistent 100% success rate in board examinations. Yet, the school’s focus has never been limited to academics. With opportunities for extracurricular activities such as skating, karate, violin, keyboard, embroidery, cinematic dance, and calligraphy, students are encouraged to discover and develop their unique talents. Assemblies are a cornerstone of daily life, where moral values are instilled, stage fear is conquered, and confidence is built.
Every great journey begins with a dream, and the story of Cornerstone International School is no exception. Cornerstone was the dream of a young Abraham, inspired by his parents who were esteemed educators. Despite limited resources, he pursued his vision of providing value-based, quality education with unwavering faith. His efforts, along with his wife Susan, materialized through the support of close friends KC & Celine.
Cornerstone International School was established in 2014 by the directors Rev. Dr. Abraham Chacko Kaitholil and Rev. Dr. K C Chacko Kalumannil under the Cornerstone Proclamation Trust, registered under the Public Trust Act.
Dr. Abraham Chacko and Dr. K.C. Chacko envisioned a place where young minds would be nurtured, values instilled, and lives transformed. This vision was not born overnight but cultivated over years of prayer, patience, and unwavering faith.
