Extension programs are semester- or year-long academic studies away from NCS. These programs typically offer traditional classes but may also focus on a particular subject such as language, leadership, or science. There are many extension programs for high school students, and NCS supports student participation in those programs that offer a rigorous academic experience without significantly delaying or interrupting a student's course of study at NCS.
Extension programs are opportunities to develop independence, gain leadership skills, explore areas of interest, take risks, meet students from around the world, and, in some ways, preview a college experience. They can be incredible experiences, but they aren't for everyone, and it takes careful planning to participate in such a program.
