The Northern Illinois University Lifelong Learning Institute (LLI) is a member-directed group of retirement-age people who seek new learning experiences. Members, regardless of their education, enjoy continuing to learn in an informal, flexible, and non-competitive environment with individual participation. They rekindle old interests and pursue new ones at a reasonable cost without being concerned with credits, grades, exams, or prerequisites.
Members determine the topics offered in study groups, workshops, and lectures and often serve as LLI conveners, instructors, and discussion leaders. In some instances, non-members with particular expertise may also serve as volunteer conveners.
A self-supporting institute, the LLI relies on members' dues for its financial needs and on member volunteers for all committees and program administration.
