EDUCATION Minister Leighton Andrews has announced Wales will set its own grading system for English language GCSEs in an attempt to avoid a repeat of the 2012 re-grading row.
Grade boundaries had previously been shared between Wales, England and Northern Ireland but Mr Andrews has said they will no longer be agreed.
The move has been criticised by exam board the WJEC.
He said: "I am determined learners in Wales should have confidence that they achieve the grades their work deserves and other stakeholders should also have confidence that this is the case.
"New conditions will ensure the awarding of GCSE English language qualifications in Wales will be separated from the arrangements for English language in England."
A spokesman for the WJEC said: "Qualifications in core subjects such as English language are used by learners as either a passport to employment or to further study.
"It is essential we continue to work with regulators and with other awarding organisations to ensure comparability and consistency of standards within the GCSE brand."
