The Clarkson School (TCS) is an early college entrance program that replaces the traditional senior year of high school. Students take regular college classes with Clarkson University first-year students and live on campus in a residence hall reserved for Clarkson School students. At the same time, students are immersed in a supportive environment with specialized programs and activities that bridge the transition between high school and college. After students complete the year, they can continue as sophomores at Clarkson University or move on to other prestigious colleges and universities. Start here. Go anywhere.
