The Trades Union Congress accredits its programme through the National Open College Network (NOCN) to provide clear national recognition of the quality of courses and the achievement of union representatives and its members. Registration for accreditation is voluntary. There are no tests or examinations. You will build up a file, which shows the work you have completed during the course, and NOCN credits are awarded for achieving the learning outcomes for that course. The NOCN will issue you a certificate too. Credits can be built up over a number of years and are transferable thought the country.
