Estyn says schools must develop staff leadership skills
Schools must develop the leadership skills of staff at all levels, says the Welsh education watchdog.
Estyn has compiled a report on leadership, highlighting those leading the way.
It said nearly all those schools visited have confident senior leaders, but recommends they develop a culture of improvement.
Chief inspector Meilyr Rowlands said it is important for schools to support staff.
The report involved interviews with teachers and learning support staff as well as analysing school improvement plans and studying inspection reports from 2010 to 2014.
Recommendations said staff should get career development, local councils should provide more guidance and the Welsh government should implement a strategy for developing leadership in schools.
Ms Rowlands said: "Although in some schools there is good practice, the opportunity to develop key leadership skills is not available in all schools and there is a particular shortage of Welsh-medium training."
