Coleg Cymraeg Cenedlaethol currently coordinates a number of schemes that aim to develop students' language skills:
- Language Skills Certificate (TSI) - a certificate that shows students' ability to communicate proffesionally both in writing and orally through the Welsh.
- Language Competancy Cetificate for Teachers (TCA) - a certificate that shows the level of Welsh language skills of trainee teachers.
- Cynllun Colegau Cymru - a framework for teaching Welsh as a second language to trainees studying primary teacher training courses. A certificate is awarded at the end of their course indicating their level of language skills in the context of learning and teaching.
More information about the individual schemes can be found by clicking on the links to the right.
