Schools in Band 1 are considered the best performing, while those in Band 5 score the lowest.
2013 is the third year that the data has been published.
Nearly 80% of schools have stayed in the same band or moved up/down by one band between 2012/13.
One school - Ferndale Community School - moved from Band 5 to Band 1.
Banding data is crucial in helping us see how our schools are doing, allowing us to direct support to those schools which need the most help to improve.
If we’re to improve the performance of schools across the board in Wales we need to both challenge and support them. Challenge if they’re underperforming or coasting, but offer the support they need, financially and through sharing best practice, to deliver the best results for our young people.
It’s encouraging that since Banding has been in place absenteeism has fallen and we’re seeing improvement in our exam performance.
Recent statistics show an all time high of 15 year olds in Wales achieving the Level 2 inclusive, in other words five good GCSEs including grades A* to C in English or Welsh first language and mathematics.
We’ve seen this reflected in Band 5 schools last year improving their Level 2 inclusive performance by 10 per cent in 2013. We continue to narrow the gap with England on GCSE performance and that’s very encouraging.
