Each school participating with SIWH is assigned its own instructor. This instructor visits the school and delivers a 15 week curriculum to the agreed upon grade levels. The students have the program oce per week for a designated time, and the instructor provides activities and lessons that build on one another throughout the year. The SIWH program becomes an integrated part of the school environment. Student, teacher, and parent involvement is encouraged throughout the year through discussion, workshops, and events.
