Higher education: discipline or field of study?

Higher education, or more strictly higher education studies, is sometimes referred to as a discipline, though it is more often referred to as a field, sector or area for study. But what is a discipline and does higher education studies, at its current state of development, qualify as one? This article re-considers these matters and comes to some conflicting conclusions. The issue of whether higher education studies is, or is not, a discipline should probably, therefore, be regarded as still open for debate.
