The BBC has recently run an interesting piece about the relationship between class sizes and teachers’ salaries, based upon some OECD data. The article headed ‘when class sizes fall so does teachers’ pay’ is an interesting thesis. https://www.bbc.co.uk/news/business-47281532 However, how does it relate to the first law of economics that when there is a shortage of supply, and demand remains consistent, either the price will rise or substitution will take place?
The nightmare scenario for government is that facing the secondary sector in England at present. Pupil numbers are on a rising curve, at least until the middle of the next decade. This means more funding will be required, even if the unit of funding per pupil falls in real terms. At the same time, there is a labour shortage that is growing worse in some parts of the curriculum.
Hence, demand for more cash for schooling since, as the BBC pointed out, it is a fact of school life that staffing costs, and especially the cost of teachers, consumes the largest part of any school budget. However, schools are competing with other government services for cash and it seems likely that in England, however hard the teacher associations press their case, the cash needed for the extra pupils will come before any significant uplift in funding per pupil.
So, to that extent, larger classes is one way to fund better pay for teachers. However, most schools, and especially secondary schools, are constrained about how far class sizes can be increased, due to the physical nature of their buildings and the dependence on a classroom based building model.
In England, there may be the space to increase pupil-teacher ratios, perhaps back to where they were around the turn of the century, but that is likely to come from altering contact ratios – the amount of time teachers spend in the classroom – as much as from increasing class sizes. The trade-off of worsening contact ratios will almost certainly be a rethink about workload, since making the job of a teacher look even harder won’t help recruitment into the profession.
There is one helpful point for the government in England, but probably not for parents, and that is the fact that in England children have no right to be taught by anyone with knowledge and training in the subject they are teaching. Indeed, in extremis – nowhere defined except in very vague terms – children can be ‘taught’ by those with no background knowledge or training in what they are asked to teach. So long as there are enough people willing to be teachers, then pay can be kept under control. And, as everyone knows, there are plenty of arts and social science graduates for whom a teaching salary can still look attractive.
Today The Pearson Group published its annual results. Might their experience point to another way forward? The substitution of capital – in the form of IT and AI – for labour? So long as the learner is engaged, as there are in higher education, this may well be part of the way forward. But, for those that see schooling as a struggle between the generations, rather than the development of future wealth and happiness, the physical presence of a teacher overseeing learning has much to recommend it.
Who that teacher might be, and how well they will be paid, will, I am sure, still feature large in the future debates about the economic of education.
