The education watchdog Estyn says little has changed with children's reading and writing skills, despite a major drive, launched three years ago to improve standards for youngsters going into secondary schools.
The report on one of the Welsh Government's flagship policies found that while 'modest' progress has been made it is still not producing results.
Key findings included:
The strategy was introduced quickly, which means schools didn't have enough time to prepare resources
There has been a lack of guidance for schools on preparing assessments, standards and test materials
Teachers weren't able to access the proper training they needed to make the strategy work.
