Arundel School offers both weekly and full boarding. The boarders are provided with a secure, nurturing and comfortable environment in which the girls learn and acquire independence, tolerance and graciousness. Boarders hail from the local suburbs, all over Zimbabwe and throughout the region assisting parents who either live a distance away or those whose lifestyles require in residence children. Being situated on 100 acres with numerous amenities, boarders are encouraged to utilise their free time pursuing activities in the company of their friends. The level of freedom for full boarders depends on the age of the student however there are 2 Fixture Free weekends most terms and boarders may take two other exeats per term. Boarding is living in a community, however, what is lost in privacy is gained in companionship. As part of a close and supportive community, friends are made for life and opportunities are present to stay in touch with old friends.
The boarders attend a weekly evening Chapel service conducted by the senior girls. On the last Sunday of each month parents and visitors are welcomed to participate in the Holy Eucharist service.
