Illinois College has a long tradition of academic excellence. The College has always been a small private college of liberal arts, believing in the development of character and personality as well as intellectual training. It is believed that this development is best effected in the intimacy of association among students and faculty of a small institution where all may remain individuals. More than fifty years ago the unusual quality of the educational program at Illinois College was recognized by the establishment of a Phi Beta Kappa
chapter on the campus; this was the fifth of eleven chapters now authorized in Illinois, and it is one of only 262 such chapters in the nation. Numerous Illinois College graduates are listed in "Who's Who in America". Alumni of Illinois College have distinguished themselves in public service and politics, the professions, and corporate leadership.
Illinois College is Accredited by the Higher Learning Commission and a member of the North Central Association.
It also is a member of the Association of American Colleges, the National Association of Independent Colleges and Universities, the Council of Independent Colleges, and the Federation of Independent Illinois Colleges and Universities. It is also recognized by the American Association of University Women and the Illinois Office of Education.
