Distance education in the American education system continues to expand. However, despite technological improvements and nearly universal accessibility to the Internet, adult learners continue to experience barriers to accessing distance education courses and programs. Building on prior work by Cross (1981) and Darkenwald and Merriam (1982), this literature review focuses on the institutional and student barriers experienced by adult learners. Institutional barriers consist of program costs, resource availability, lack of equipment and infrastructure, scheduling, instructional concerns and technical assistance. Student barriers include costs and motivators, feedback and teacher contact, alienation and isolation, student support and services, and a lack of experience and/or training. Recommendations for addressing institutional barriers include continual evaluation of noninstructional areas, faculty training, and adoption of new technologies. Recommendations for alleviating student barriers include providing opportunities for distance students to interact with faculty, other students, and other parts of the campus, providing toll-free phone support to all areas of the campus, requiring faculty to have online office hours, and developing electronic tutorials for new distance students.

The use of distance education in the United States continues to grow. A recent study by the National Center for Education Statistics (Waits & Lewis, 2003) documented the increased use of distance education in a multitude of academic and technical disciplines in postsecondary institutions. Private industry and business, along with governmental agencies, have also recognized the attraction of learning “any time and any place” in providing education and training opportunities for their employees.

Relieving adult learners of the time and place constraints of a traditional classroom, distance education can present a new set of constraints, or barriers, to accessing educational opportunities. These barriers can be significant for adult learners, many of whom are “non-traditional” students, i.e., older, employed, needing job skill updates, seeking career change, or returning to college after a long absence. These students may also be single parents or transfer students, who, because of family responsibilities, work commitments or geographic limitations, are seeking to access educational opportunities at their convenience. Distance education offers the promise of unfettered access for these individuals; however, at present, the promise remains unfulfilled.
