Week Without Walls trips are planned and led by professional outdoor education providers with an emphasis on safety and are chaperoned by XIS teachers. Students engage in a variety of team building and challenge activities such as rock climbing, mountain biking, and camping and are generally only allowed to use personal electronic devices for a short time each day.

Students are expected to participate in the Week Without Walls program. If students are unable to participate, they will need to work with the CAS coordinator to devise an alternative program to meet CAS outcomes during the week. This may involve service projects at XIS or in the community.
