The Welsh Government has stressed that schools being categorised by their local authorities has been going on for some time - and that the process will continue under the system of four new education consortia aimed at improving standards around Wales.
In January, it said "all consortia categorise their schools, but they use four systems. A single national categorisation model will ensure that the regional consortia are assessing schools in a consistent way."
The Welsh Government has had to repeatedly deny that the national categorisation model is replacing the controversial secondary school banding system, and faced criticisms that it has provided too many forms of assessment for schools.
Secondary school banding is here to stay. Primary school grading will be introduced by autumn 2014.
Our ongoing review of banding will develop the best way for Welsh schools to track their performance and potential for improvement but we must be clear that local authorities already categorise their schools and have done for some time.
This process exists alongside current banding arrangements and now fully established consortia are keen for that to continue.
We envisage banding data and primary grading data will be used to help consortia with their categorisation.
The Welsh Liberal Democrats say the announcement that the secondary banding system will be "revised" from this autumn, and run alongside a new National Categorisation System, will create "more confusion" in schools, as they are being assessed in too many different ways.
There is already a great deal of confusion, with many schools placed in a position where assessment and monitoring can be undertaken in a number of ways: banding, the National Categorisation System, Schools Challenge Cymru, and schools inspection body Estyn.
The result is a complex and unnecessary series of data collection methods which does nothing to give schools the promised “clear way forward” to improvement.
We said in January that if a new system of categorisation was introduced then banding should go and we stand by that statement.

The Welsh Government said in January that "a single national categorisation model will ensure that the regional consortia are assessing schools in a consistent way", and that the system already works alongside banding.
There is little detail on how the categorisation model works.
Headteachers union ASCL Cymru has predicted that the controversial secondary school banding system will be scrapped after 2016, and fully replaced by the new 'National Categorisation System'.
The Welsh Government has previously insisted that "banding is here to stay" and today announced it would be "revised" from this autumn, alongside the categorisation model, developed by regional consortia.
Robin Hughes, secretary of ASCL Cymru, has said that the categorisation system "has merit and promise" - without the "yo-yo grading" of banding.
The Welsh Government has announced that its controversial banding system for secondary schools will be "revised" from this autumn - and a new "grading" system for primary schools will also be introduced later in 2014.
Secondary school banding was introduced in 2011, but teaching unions and opposition parties have criticised it as based on crude measures and volatile - with some schools jumping several bands from one year to the next.
In January, Education Minister Huw Lewis insisted "banding is here to stay", after reports it was to be scrapped - but that a planned review after three years was underway.
Mr Lewis said today that the measures included in banding "are being reviewed to ensure that the model continues to align with our priorities for education, in particular with a focus on reducing the impact of deprivation on attainment."
There is no more detail on how a new system could work.
Plans to introduce a similar ranking system for primary schools were delayed in 2012, with previous Education Minister Leighton Andrews saying the introduction of annual reading and numeracy tests for pupils in Years 2 to 9 would provide the data needed to band schools.
Those tests were introduced last year, and pupils are sitting the second set of them over the next week.
Education Minister Huw Lewis said today: "A primary school grading model is also being developed to help us better identify schools most in need of support. It will give parents across Wales a clear picture of how schools are performing."
He also reiterated that the reviews of secondary banding and primary grading would happen alongside a new 'National Categorisation' System', from the regional education consortia, which is designed to identify what support struggling schools need.
Responding to the Western Mail's report of a new colour-coded ranking system for Welsh schools, the Welsh Government has appeared to confirm it is introducing a different model for categorising school performance, which it said will provide national consistency.
It has though insisted the existing banding system is not being replaced.
Banding is here to stay. We’ve said all along that we would be looking at it to make sure that it’s effective and meeting the needs of education in Wales. That work is ongoing. As and when we’re in a position to make an announcement we will.
Categorisation by consortia is not new - all consortia categorise their schools, but they use four different systems.
A single national categorisation model will ensure that the regional consortia are assessing schools in a consistent way. It will also provide a robust way for consortia to identify the support and challenge that schools require.
The Welsh Government has insisted that the controversial system of banding secondary schools is "here to stay", after the Western Mail reported that it was to be replaced with a "tough new ranking system."
Banding - where schools are ranked in five bands, based on GCSE results, performance in specific subjects, attendance and the achievements of pupils of poorer backgrounds - was introduced in 2011, and three sets of tables have been published so far.
