The publication of the 30TH Report of the School Teachers’ Review Body (STRB) Report earlier this week contained the usual chapter on the state of the labour market for teachers. As is often the case, the DfE provided a set of data with their evidence that found its way into the relevant chapter of the report.
One such table was for the Pupil Teacher Ratios for Qualified Teachers, by primary and secondary sectors for all state-funded schools
The STRB table appears to have used data from the School Workforce Census up to 2018. The 2019 data presumably appeared too late to be included in the Report, but I have added it to the Table for the purpose of completeness.
| Pupil to teacher ratio (Qualified) within-schools for ‘Pupil-teacher ratios’ | |||||||||
| 2011 | 2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | |
| LA maintained nursery and primary | 21 | 20.9 | 20.9 | 21 | 21.1 | 21.3 | 21.7 | 21.5 | 21.3 |
| LA maintained secondary | 15.6 | 15.5 | 15.7 | 15.8 | 16.1 | 16.4 | 16.7 | 17.2 | 17 |
Curiously, the data from the DfE site on the School Workforce Census for Qualified teachers in 2018/19 differs from the numbers in the STRB Table as the extract from the DFE site reveals.
| Table showing Pupil to teacher ratio (Qualified) within-schools for ‘Pupil-teacher ratios’ from ‘School workforce in England’ in England between 2018/19 and 2019/20 | ||

| LA maintained nursery and primary | 21.3 | 21.3 |
| LA maintained secondary | 16.7 | 17 |
I don’t know the reasons for the apparent differences between the two datasets. The new method of producing statistics on the DfE site makes time series data more of a challenge to create for those used to the former presentation. I am sure that the new system will allow for easier interrogation of the data, one the initial challenges have bene overcome. However, it does alter the dynamics of the relationship with the data if you can only ask pre-set questions, and cannot eye-ball the dataset for possibly interesting patterns that have not occurred to the statisticians in the civil service.
There are couple of odd anomalies in the Secondary PTR data for 2019. Two unitary authorities, Portsmouth and Telford & Wrekin, are recorded as experiencing very large changes between 2018 and 2019. In the case of Portsmouth’s data about Qualified Teachers in the secondary sector, the PTR went from 16.7:1 to 18.5:1 in one year. This is well outside the normal degree of change.
In the past there have been errors recorded in the PTR tables. Indeed, one year a Volume of Statistics of Education – Teachers had to be recalled as there were so many mistakes. More recently, a glitch resulted in mistakes for some local authorities in Yorkshire and The Humber Region appearing in one version of the table.
Finally, it is worth noting the relationship between school funding and PTRs. The direction of travel is a good lagging indicators of how well schools are funded, especially now that funding is so closely related to pupil numbers.
Should the remaining shire counties be reformed into unitary councils in the autumn, as has been predicted, then 2020 might be the last time for some years that PTR data will provide anything like a reliable picture of staffing trends in schools across a whole swathe of rural England.
