Failing schools: Merthyr Tydfil and Monmouthshire warned of special measures
Two education authorities should be placed into special measures, according to a damning report.
Monmouthshire and Merthyr Tydfil are the latest to be criticised by the schools watchdog Estyn for failing their pupils.
Three other authorities are already in special measures.
Education Minister Leighton Andrews says he is considering setting up independent boards to oversee the improvements needed.
