Welsh government warned over education six years ago
Questions have been raised over how concerns for education in Wales, first highlighted six years ago and raised again this month, were not addressed.
A confidential document from 2007, seen by BBC Wales, detailed weaknesses in strategy and calls for improved teaching.
The findings were similar to a critical report by the worldwide Organisation for Economic Co-operation and Development (OECD) released this month.
But the Welsh government said "positive progress" on standards was being made.
BBC Wales' education correspondent Arwyn Jones reports.
