St. John's School is a centre of national integration. It believes that a sound moral, physical, and cultural training is as important as academic and scholastic instruction in preparing students for their role in life. Hence, great importance is attached to games, sports, and other extracurricular activities which keep the students mentally alert and abreast of the time.
The school, through various activities, inculcates in students a positive inclination towards upholding social and economic justice, dignity of the individual, irrespective of caste and creed, appreciation of our cultural heritage, and concern for the environment. Through its founding motto 'TRUTH ENLIGHTENS', students are prepared to engage in an ongoing pursuit of knowledge. The fruit of such an endeavor is to get closer to the truth that enlightens, transforms, and liberates a person. Our motto precisely aims at this.
