Systemization of Educational Quality Management

Multi-ethnic multi-cultural Australia is an immigrant country with well developed English language teaching as a foreign language and English teaching methods.

The Education Services for Overseas Students (ESOS) Act 2000 and the National Code of Practice for Registration Authorities and Providers of Education and Training to Overseas Students 2007 (National Code) provide nationally consistent standards for providers of education and training for international students.
As an international student on a student visa, you must study with an institution and in a course that is registered on the Commonwealth Register of Institutions and Courses for Overseas Students (CRICOS). CRICOS registration guarantees that the course and the institution at which you study meet the high standards expected by international students.

Along with the ESOS Act and National Code, there are also regulatory and quality assurance organisations for higher education – TEQSA(Tertiary Education Quality Standards Agency) and VET institutions.
