St. Anthony’s School, Kurseong is primarily a residential school with most of the students boarding in 'dorms'. The school prides itself on its ability to provide students with relatively well equipped dorms. All dormitories are well-ventilated, spacious, well organized with adequate furniture and other amenities. Boarding starts from Class III.

An experienced Matron is on to do 24 hours duty and to look after the juniors. All dorms have a Warden/Matron with efficient and diligent support personnel who are directly responsible for the care and nurture of the children in their dorm. In absence of the particular Dorm Warden/Matron, the support personnel are in charge and responsible for the dorm.
