The Advance College Project (ACP) is a partnership between Indiana University and participating high schools within the states of Indiana, Ohio, and Michigan. ACP offers college credit to qualified high school seniors (and some juniors) who enroll in IU general education courses that are offered at their local high schools during the regular school day and taught by certified high school teachers who hold adjunct lecturer status with Indiana University. ACP courses are administered from the IU Bloomington campus, as well as IU East, IU Kokomo, IU Northwest, IU South Bend and IU Southeast.

ACP began in 1982-83 with six Indiana high schools, enrolling 269 students, and offering chemistry, math, and English composition courses. Today, ACP operates in more than 100 high schools across Indiana and in Michigan and Ohio and works with more than 300 instructors who teach ACP courses to well over 2,500 students earning more than 12,500 IU credit hours. Student response to ACP coursework demonstrates that the ACP experience is beneficial. As new schools are brought into ACP, educational opportunities for college-bound high school students expand.

ACP is for high school students, generally juniors and seniors, who have adequate preparation and the desire for more advanced work. Through its course offerings, ACP provides an opportunity for high school students to begin college work while in high school. ACP is not a gifted and talented program. ACP courses are actual college courses intended to allow a wide range of students to engage in college-level work for college credit. ACP courses are designed for students with a solid academic foundation, interests that can be furthered by acquiring college credit prior to high school graduation, and a serious commitment to completing the ACP course successfully.

ACP courses provide both high school and college credit (concurrent enrollment) and, therefore, allow students to fulfill requirements for high school graduation and requirements for college admission while beginning a college transcript. The same general standards that apply for admission to Indiana University apply to students seeking to enroll in ACP courses. However, student participation in ACP courses does not constitute admission to IU.
