Data calculation/treatment
These figures present statistics relating to the predominant field(s) of study of students enrolled at tertiary education providers. This data looks at all the courses studied within a qualification to determine a student’s predominant field(s) of study. For example, you might use this data to know how many students are specialising in Information technology.
The Ministry of Education has revised the method used to derive the predominant field of study of students/graduates in tertiary education providers. The same method is now be used for both student enrolments and graduates.
Students are counted in each field of study they enrol in, so the sum of the various fields may not add to the total.
Students are counted in each qualification type/level they enrol in, so the sum of the various levels may not add to the total.
