The Standards are duties imposed on organisations by the Comissioner to use the Welsh language in the following areas:
- Service delivery
- Policy making
- Formulating new policy
- Operational
- Promotion
- Record keeping

The Standards give Welsh speakers the right to use the language when dealing with those organisations.
The Commissioner also has powers to enforce organisations to comply with the standards that have been imposed on them.
Welsh language standards promote and facilitate the Welsh language, and ensure that the Welsh language is not treated less favourably than the English language in Wales.
