College in the Schools (CIS) is an educational program for high school students run by the University of Minnesota. It allows students to take college level classes in their high school and, as a result, earn college and high school credit free. The classes are taught by high school teachers who receive several weeks of additional training by the University of Minnesota. The curriculum is controlled by the University of Minnesota. More than 100 high schools in Minnesota participate in the program. Unlike programs such as Post Secondary Enrollment Options, the school district still receives funds from the state for students who enroll in the program. Many schools who do not offer Advanced Placement or International Baccalaureate classes offer CIS.
The program was started in the 1986–1987 school year, at the same time as several other school choice programs were started in Minnesota such as Post Secondary Enrollment Options and open enrollment. Initially only literature and composition courses were offered but now 31 introductory courses are offered which are sponsored by four University of Minnesota colleges: University of Minnesota College of Liberal Arts, University of Minnesota College of Food, Agricultural and Natural Resource Sciences, University of Minnesota College of Education and Human Development and University of Minnesota Institute of Technology.
Columbia University found that students who took dual enrollment courses in high school were more likely to graduate from high school and enroll in college, as well as three years after high school graduation, students who had participated in dual enrollment courses in high school had earned higher college GPAs and more postsecondary credits than their peers.
Research shows that colleges and universities nationwide accept dual enrollment credits at almost the same rate as they accept AP scores, though it greatly depends on the institution from which the credit originated from. College in the Schools dual enrollment through the University of Minnesota is accepted almost universally coast-to-coast.
