The College began after a grass-roots movement by Littleton residents, led by Littleton activist Virginia Baker,  to provide post-high school education in the area.  Arapahoe Junior College began with 550 students.
After some years of independent operation, ACC joined the Colorado Community College System, comprising 13 institutions. In 2013, Frank Lee Earley (one of the founding faculty members) self-published an illustrated memoir, "The View From the Fourth Floor: A Personal History of Arapahoe Community College, 1965–2005",  which gives a first-person account of the founding and growth of the college.
ACC now serves over 21,000 credit and non-credit students yearly across its three campuses in the southern portion of the Greater Denver Metropolitan area:

ACC is accredited by The Higher Learning Commission and a member of the North Central Association of Colleges and Schools. It has an open-door admissions policy as well as a "concurrent enrollment" program for high school students, allowing such students to earn college credits while still enrolled in high school. In the 2014–2015 academic year, high school students accounted for about a quarter of ACC's total enrollment. 
The College offers over 90 degree and certificate programs. In addition to its traditional classroom learning environment, ACC has over 200 courses available online. These classes, which include classes such as accounting, mathematics and history, can be used to count towards an associate degree. ACC uses the online learning management system Desire2Learn as the platform for online classes. 
In 2013, Frank Lee Earley (one of the founding faculty members) self-published an illustrated memoir, “The View From the Fourth Floor: A Personal History of Arapahoe Community College, 1965–2005.
