Field of Education Overview When you search for a course on this website you may need to select a "field of education". The "field of education" structure is a classification system used by Australian education providers to describe courses, specialisations and units of study. The main purpose of the classification is to ensure courses, specialisations and units of study with the same or similar vocational emphasis are classified to the same field of education. The "field of education" structure has three levels: broad field; narrow field; and detailed field. The classification uses the concept of vocational emphasis for coding courses and specialisations. Broad These fields are: the broadest categories of the classification; they are denoted by 2-digit codes; and distinguished from each other on the basis of theoretical content and the broad purpose for which the study is undertaken. Narrow These fields are: sub categories of the broad fields; denoted by 4-digit codes -- the relevant broad field code plus two additional digits; and distinguished from other narrow fields in the same broad field on the basis of the objects of interest and the purpose for which the study is undertaken. Detailed These fields are: sub categories of the narrow fields; denoted by 6-digit codes - the relevant narrow field code plus two additional digits; and distinguished from other detailed fields in the same narrow field on the basis of methods and techniques, tools and equipment, and a stricter application of the criteria used for broad and narrow fields.
