The administrative offices of the school are housed in the building closest to the main entrance. Five Vice Principals help the Principal in the day-to-day running of the school. They have their individual offices for administering to the needs of the students. They deal directly with teachers and parents concerning the students in their respective sections. The five sections under the Vice Principals are the Plus Two Section (Classes XI and XII), High School (Classes VIII to X), Middle School (Classes IV to VII), Primary School (Prep to III) and Social Service School (Classes Prep to VI).
St. Xavier’s Social Service School provides quality education up to Class VI to the children of the neighbourhood, who would otherwise be deprived of it, for financial and other reasons. Each year some of the brightest from Class VI are absorbed into the English medium. They are assisted financially to complete their school education at St. Xavier’s.
