The Welsh Education Minister Leighton Andrews has been defending his decision to order a regrade of English language GCSEs last year.
He is being questioned by MPs on the Commons Education committee.
He told the committee that the regrade was "action taken to deal with an unfairness."
He criticised the UK education secretary Michael Gove for refusing to meet him and his Northern Ireland counterpart.
