Forty years ago, I wrote an article about variations in local authority provision for education that appeared in the Oxford Review of Education (Volume 8, No2). Part of the discussion in the article centred around the range of pupil teacher ratios within schools after local government reorganisation outside London in 1974 had completed the changes to the local government landscape started in London a decade before.

Of course, our school system was very different in 1974. Most authorities were still transiting from a two tier selective system to a fully comprehensive system; most based their new systems upon the traditional two tiers, but some used one of the variations of first, middle and upper schools that constituted the three tier system.

Local authorities had the freedom in the 1970s to decide how much of their funding to spend upon schooling, and although there were national guidelines on spending on resources and staffing, they were not mandatory. However, teachers’ pay, then as now the largest item of a school’s expenditure, was centrally controlled, as was the ratio of promoted posts to classroom teachers. The differential between the highest paid teacher and a classroom teacher was much narrower than it is today, especially in the secondary sector.

On the staffing side, there were few support staff, and hardly any classroom assistants working in schools forty years ago, so one class one teacher was very much the model across the board, with classroom teachers in the primary sector, and comprehensive schools following the model of the selective sector with subject specialists replacing classroom teachers that had been commonplace in some secondary modern schools.

Pupil Teacher Ratios (PTRs) can be calculated in the same way today as they were in 1974. Helpfully, the DfE published the results for all state-funded schools in England, by local authority, based upon the data collected in the November Staffing Census. The latest data, published in June 2022, was from the November 2021 census, so now some 14 months old.

What is interesting, despite the changes in local government boundaries is to compare the range of 1974 PTRs in the secondary sector with those from the 2021 census.

	Best PTR	Worst PTR	difference
1974	15.7	19.7	4
1980	13.6	18.6	5
2021	13.6	18.4	4.8

 Compared with 1974, the difference between the best and worst local authority areas was greater in 2021 than in 1974, and similar to the difference in 1980 when the article was being prepared. What is noticeable is that both the best and the worst levels improved between 1974 and 1980, but are now, forty years later, still very similar to where they were in 1980. This despite academies, unitary authorities and the devolution of budgets to individual schools.

Even more interesting is the position of London schools. In 1980, London boroughs occupied eight of the top ten places for ‘staffing’, using data from the Chartered Institute of Public Finance and Accountancy data. In the 2021 census, four outer London boroughs have dropped down the ranking, as has Newcastle, to be replaced by northern towns and cities. However, London, now with individual boroughs rather than the combined Inner London Education Authority still takes a disproportionate number of the places in the authorities with the most favourable PTRs.

Since 2010/11, all but two local authorities with data for the whole period have seen a deterioration in the secondary PTR for their area. Slough and Southend on Sea, both authorities with selective school systems, have seen the biggest worsening in secondary PTRs over the period of Tory government.

With the pressure on funding, it is interesting to speculate what the outcome of the 2022 census will be when published this June. Could we witness some of the worst secondary PTRs in half a century?
