There is no commonly accepted definition of an adult learner. The best that most educators are able to do (and still feel relatively satisfied with the attempt) is to recognize certain characteristics commonly attributed to adults. For example, adult students characteristically engage is multiple roles that affect both the amount and quality of time they devote to learning. Too, adults typically bring more life experiences to the classroom than traditional students. Experiences often provide a rich source for grounding their learning and for building a basis for new knowledge. Sometimes, these experiences interfere with learning and must be set aside, replaced with new schemata for acting on novel situations. Many adults find that formal education (especially returning to school after years spent in pursuit of career goals) serves as an especially uneasy transition point in their lives. As adults move through a series of stages such as education, insecurity and uncertainty is commonplace. Adult students frequently have established educational goals (especially when compared to their traditional counterparts). They are more likely paying for their education, focused on off-campus activities, and are likely to be peers (age-wise) or even older than their instructors. Adult education constitutes those interested in teaching adult learners or who are already working with adults in an educational capacity and would like further certification and professional credentials. Studying adult education gives candidates further knowledge, training, skills, understanding and appreciation of adult education as its own unique area of practice and study. Although many of the philosophies, psychologies, and leadership traits for the adult educator are similar to those focused on the traditional learner, the history and sociology of adult learning is different. Topics particular to adult education include administration, curriculum development, learning and teaching methods and adult education as it relates to social change, current trends and global context. Those interested in focusing on adult education at whatever level find themselves as adult English as a second language (ESL) teachers, continuing education teachers and professors, or teachers of adults seeking a high-school diploma. Others provide General Educational Development (GED) preparation, literacy
