At Shield Defence Academy, a leading NDA coaching institute in Lucknow, we often guide young aspirants starting early through Sainik Schools. To apply for Sainik School admission, students must typically be in Class 6 or Class 9 and fall within the age limits specified for that academic year (usually 10–12 years for Class 6, and 13–15 years for Class 9 as on March 31 of the admission year). Only Indian citizens are eligible, and both boys and girls can apply. Sainik Schools lay the perfect foundation for NDA, and Shield Defence Academy supports students at every step of this journey.
