The average secondary school has placed 10 adverts for teachers during 2019. The figure is higher for most schools in London and the Home Counties and lower for many schools in the north of England.

The data are from TeachVac www.teachvac.co.uk the leading job boards for teachers looking for posts anywhere in England.

Of course, the average is a crude measure, as it isn’t related to the size of the school in terms of its pupil population. There are schools with more than 2,000 pupils and also at the opposite end of the scale there are those with only a few hundred pupils.

Once the year is over, TeachVac will link the number of vacancies to the pupil roll of the school, as supplied by the DfE in its data, and compare the outcome with indicators such as the percentage of pupils with Free School Meals. As TeachVac has data for several years, it will be possible to start to identify trends and whether there are certain types of school where staff turnover is more common.

Of course, now that the number of pupils entering secondary schools is on the increase, and there are also new schools being established, the picture is not as clear cut as if it were a steady state in relation to the size of the secondary school population.

The data also reveals how the demand for teachers corresponds to the supply, at least for new entrants. Data on returners seeing work is still patchy, and a national register might be a useful tool for the new government to consider.

After all, what is the point of training teachers if there are also returners willing to work as teachers? As I have said before on this blog, enticing mature entrants into teaching and then not offering them work is a wasteful misuse of human resources. Nowhere can this be seen more clearly than in the Humanities.

There are far more history and geography trainees than required by schools. History trainees, unless lucky to be on Teach First or School Direct Salaried Scheme, have to pay fees and find the cost of looking after themselves during their training, all this expenditure with no guarantee of a job.

This year, 2019-2020, according to DfE figures, some 178 history trainees are being supported by public funds (65 on School Direct Salaried Scheme and 113 on Teach First). By comparison, some 1400+ trainees are using student loans and other funds to train as a teacher.

With such over-recruitment into training, it isn’t clear why the government allowed spending on 178 history trainees at a cost of perhaps £400,000 of public money? That’s unnecessary public expenditure. Add in those 130 geography and PE trainees also on salary schemes, subjects where supply of trainees also exceeds demand for teachers, and the cost to the public purse is well over half a million pounds.

The current hybrid system of training teachers looks overdue for a re-think. Whether it will get one from the next government is probably unlikely while planning for Brexit continues to dominate the agenda.
