Five Pembrokeshire secondary schools have dropped bands in the latest Welsh Government banding results.
Pembrokeshire now has no schools in the highest Band 1 but two in the lowest, Band 5 (Tasker Milward and Milford Haven).
The Welsh Government’s banding system involves using national data on school performance to group secondary schools into one of five bands.
Those in Band 1 show good overall performance and progress; those in Band 5 show lower performance and progress in these indicators.
In 2013 Pembrokeshire three schools remain in the same band as last year while five are in lower bands.
The county’s secondary schools are now banded as follows:
• Sir Thomas Picton (Haverfordwest)
• Greenhill (Tenby).
• Ysgol Dewi Sant
• Ysgol Preseli (Crymych)
• Ysgol Bro Gwaun (Fishguard).
• Milford Haven
• Tasker-Milward (Haverfordwest).
In 2012 all eight county secondary schools were in Band 2 and Band 3.
In 2011, Ysgol Preseli was in Band 1, the only Pembrokeshire secondary school to have been in Band 1.
Pembrokeshire County Council Leader, Councillor Jamie Adams, said: "The banding presents a mixed outcome for our schools.
“We are working with the schools identified as needing to improve their position.
“Pembrokeshire, like other local authorities in Wales, uses the outcomes of the school banding process to support school improvement.
“It is one part of a series of performance indicators used that support the evidence in self-evaluation.
“When used constructively and in context, it provides a good range of data demonstrating trends and annual performance. Schools are challenged and appropriate support and targeted interventions are undertaken.
“Since the data was available to schools and the local authority during the summer, appropriate interventions and support are now in place.”
Shadow Minister for Education Angela Burns, AM for south Pembrokeshire, said: “Serious questions persist over a system that remains unconvincing and unproven.
“I am not satisfied that banding – as it stands – has any real value for education in Wales.
“If we are going to measure school performance, the systems involved should be fair and equitable, and comparable like-for-like. I do not believe that is currently the case.”
