Increasing pupil numbers and pressure on funding , it seems, having an effect on class sizes in the secondary sector. Last week’s DfE data https://www.gov.uk/government/statistics/schools-pupils-and-their-characteristics-january-2019 revealed that the percentage of classes in the secondary sector with more than 30 pupils in them was, at 8.4% of classes, at its highest percentage since before 2006 and the fifth straight year to have recorded an increase. Some 13% of pupils were being taught in classes of more than 30 in January 2019. By comparison, in 2014 it was just 9.4% of pupils.

With more increases in pupil number over the next few years, this percentage of pupils in classes of over 30 pupils seems destined to increase even further, unless more funding can be found from the magic money tree called The Tresury.

Almost the same percentage of pupils in the primary sector were also being taught in these ‘large’ classes. The classes are mostly at Key Stage 2. This is because of the Blunkett limit of 30 pupils that applies to most Key Stage 1 classes. Indeed, the 18.1% of Key Stage 2 pupils in classes of more than 30 is a record percentage since at least 2010 and probably for a longer period as well. Hopefully, these children will find themselves in smaller classes when they move on to a secondary school.

Large numbers of pupils in classes means more time is required for assessment and preparation by teachers if the different needs of every child are to be adequately catered for. This may well be adding to the pressure teachers’ face from workload that must be undertaken during term-time.

The average Key Stage 2 class in England has some 27.9 pupils in it. The range is from Trafford, in Greater Manchester, where the average is 29.7 to Redcar & Cleveland in the North East, where the average is some 5.2 pupils per teacher fewer at 24.2 pupils in the average Key Stage 2 class.

Four of the lowest five areas with the best averages for Key Stage 2 class size are in the North East and the fifth, Cumbria is also in the North of England. Some boroughs in Inner London also manage to achieve among the lowest average class sizes at Key Stage2. By contrast, urban authorities in the North West and the Midlands feature among authorities with the highest average class sizes at Key Stage 2.

Some local authority areas in the North West have always had large classes and some of the worst pupil teacher ratios in the primary sector ever since I first started looking at such statistics in the mid-1970s, when the present pattern of local government in the urban areas outside of London was established. Hopefully, the new funding formula will help to further reduce the disparity between the best and the worst authorities, although other factors may intervene to prevent an entirely level playing field, such as the age and experience of the teaching staff.
