Birchwood School of Hawken provides a number of special programs outside of the regular school day, including supervised childcare before and after school; an enrichment program that offers chess, arts and crafts, sports, math clubs, and more; and Science Olympiad team practice. Birchwood's choir and ensemble members also take part in weekly after school practice. 
At the beginning of the school year Birchwood families receive information on sign-up and fees for before and after care. The program allows for use on a full- or part-time basis or simply as-needed. Students who stay after school will have play time and a homework session.
