A major review of the schools system says the Welsh government lacks a long-term vision for education and does not do enough to support teachers.
The Welsh government asked the worldwide Organisation for Economic Co-operation and Development (OECD) to conduct the review in 2012.
The report praised "positive" learning conditions but found many weaknesses.
The most recent Pisa international education tests, which are run by the OECD, ranked Wales bottom in the UK.
BBC Wales education correspondent Arwyn Jones reports.
