The XIS PTSA mission is to enhance the educational experience of XIS children and their families by working in partnership with the Board of Directors, school administration, teachers, students and the local community.
One of the main roles of the PTSA is to organize and host schoolwide community events such as the Holiday Bazaar, Spring Fling, International Day, and Teacher Appreciation Day. All funds and donations collected during the events are contributed toward student and school activities and a portion also goes to local charity. The PTSA, additionally, organizes one-day and short-term courses that are offered to parents. Previous sessions include flower arrangement, cooking classes, and parenthood seminars.
