frequently used term As I have checked more than 500 universities' websites for the purpose of research, this is the term I have frequently encountered which is used with same meaning of Persian gerayesh. I also copied the Wikipedia definition here, which shows this.
In many universities, an academic concentration is a focus within a specific academic major, that is a field of study within a specific academic major. For example, interdisciplinary programs in humanities or social sciences will require a student to pick a specific academic concentration as a focus within their academic major, such as an academic major in Interdisciplinary Humanities with an academic concentration in Film or an academic major in Interdisciplinary Social Sciences with an academic concentration in Geography. At several art schools and liberal arts colleges, an academic concentration serves a similar function to an academic minor at other universities, that is an academic discipline outside of the student's academic major in which he or she takes a small number of classes. At Brown University and Harvard University, concentrations serve the same function as majors at other institutions.

Do the universities in Iran have a standard definition? In the US there is a clear distinction between major study and minor study
