Many educators complain that the blight of senioritis and the absence of rigor and relevance prevent the final year of high school from being the capstone year it should be. Helping seniors focus on the life-changing transition they are about to experience is an effective strategy for engaging seniors and infusing relevance and rigor in a profound way. The guidance curriculum can be a natural vehicle for accomplishing this end. Too often guidance programs in the senior year focus mostly on the postsecondary planning process, with an emphasis on either college admission or career exploration. Although this focus is essential to one aspect of the 12th-grade transition experience, there is much more that seniors must know and do to prepare successfully for life after high school such as more information about the world they are entering and better life skills. Some highly effective schools have accomplished this by developing special courses and programs that teach personal life skills to 12th graders through a student-centered approach. This article discusses New Trier High School's implementation of a student-driven guidance plan that is founded on two key premises: (1) Seniors are remarkably capable and a valuable resource to the school; and (2) Seniors are extremely eager and ready to have a voice in what they learn.
