10-year plan for teachers of Physics

I was delighted to read the Institute of Physics new 10-year plan for the teaching of physics in schools in England The physics teacher shortage and addressing it through the 3Rs: Retention, Recruitment and Retraining (England) As is to be expected from the IoP, this is a thoughtful and well argued report.

Some of the finding in this new report mirror those in the report published in January 2002 by Northumbria University, and funded by the then TTA. The Northumbria study, interestingly called ‘Supply, Recruitment and Retention of Physics Teachers’ was authored by Prof. Hilary Constable, and I was a part of the team that undertook the research underpinning the report.

Many of the conclusions in the IoP report sould apply to the whole teacher supply landscape. It is just that the labour market for teachers of physics, especially in non-selective state schools, is an extreme example of 30 years of failure to provide schools with the staff needed for the National Curriculum.

It is worth recalling that in the 2006 budget speech, the then Chancellor of the Exchequer mentioned 3,000 trainee science teachers needed as a part of the Science and innovation investment framework 2004-2014. So, the problem has been known for decades, the will to solve it has seen less drive behind it. I sincerely hope that the government takes the recommendations of the IoP report on board.

As someone that has studied the leacher labour market for more than 30 years, the idea of exit interviews has always seemed to me to be a missing a part of the picture. The DfE has wave studies with school leaders, teachers, pupils and parents, but not it seems leavers. I would be happy to manage a trial with the MATs and local authority HR department in one authority, to collect data. The Northumbria study did collect some data from early leavers, workload, the desire only to teach physics and a return to studying appear to be some of the common features of the findings.  I guess, not much has changed.

If I have a quibble with the IoP report, it would be on the table of salaries in the report. My guess is that financial services salaries are skewed by a ‘London’ effect and the teaching salary doesn’t fully record any incentives received by qualified physics teachers. I would also like to have seen how many of those with QTS are in Sixth Form Colleges and independent schools?

The idea of retraining is a sensible use of resources, as are subject knowledge enhancement courses for those considering becoming a teacher of physics, but lacking a degree specifically in the subject.

Overall, what the report demonstrates is the lack of a comprehensive strategy for the staffing of our schools and, since the demise of the TTA and its successors, no real centre for policy discussions. One wonders what the Chartered College of Teaching is doing in this field? The demise of the APPG for the Teaching Profession, supported by Chris Waterman for many years, left a vacuum for debate about teacher supply, even if Ministers chose not to listen. Hopefully, after this report, the secretary of State will act.

DfE wasting money on ITT

The latest data on applications to postgraduate ITT courses appeared this morning. Such are the wonders of modern technology that data generated on the 18th of August can be programmed to appear on the bank holiday Monday in order to keep up the sequence of posting the data on the last Monday of the month by the DfE. Initial teacher training application statistics for courses starting in the 2025 to 2026 academic year – Apply for teacher training – GOV.UK

As is already known, 2025 is going to be best year for recruitment to graduate teacher preparation courses since 2013, especially in many traditional shortage subjects, such as the sciences and mathematics. But it is not ’a bed of roses’ all round.

Three subjects have recorded fewer offers this year than last year. Two, classics and drama, will miss their target. In English it would be touch and go to meet the target by the date of the ITT census in early December from just this source of trainees. However, Teach First and other routes should mean that the target will be comfortably met. But, the applications patterns for 2026 will need careful monitoring.

Five subjects won’t meet their targets this year, even with Teach First. Computing should, although it hasn’t yet done so from the courses included in this dataset.  

The remaining subjects have all recorded increased offers this year and, in most cases, are way over target. This raises the question about whether or not the DfE should once again consider recruitment controls in some subjects. After all, although we will need teachers to cover the missing trainees in the group of ‘other’ subjects, will the 1,000 extra PE teachers offered places over the target have the appropriate skill sets to fill those vacancies? They are certainly unlikely to fill the music vacancies, but presumably could be offered business studies teaching.

Hopefully, the DfE will be matching up to date vacancy data with the targets generated from historical data to see what changes might be needed for 2026 entry.  After all, there isn’t money to waste in the public exchequer.

There also appears to be over supply in the primary sector

SUBJECT202420252025 TARGETDIFF ON 2024DIFF TO TARGET
PRIMARY106101140576507953755

But I wonder whether, as in some secondary subjects, some candidates are recorded holding more than one offer. Even so, this is a sizeable overshoot and may cause issues next September in some parts of the country for trainees seeking teaching posts in primary schools. Especially, if a combination of falling rolls and a reluctance to move jobs in a deteriorating labour market overall sees fewer posts advertised.

I believe that Ministers need to do some hard thinking about balancing supply and demand for teachers and the cost to the public purse.

Sort out physics teacher preparation courses

The next couple of years likely to see the best recruitment levels to physics ITT courses for more than a decade. As a result, there might be a risk that everyone concerned with teacher preparation breathes a huge sigh of relief, and put the problem of the shortage of teachers of physics in the ‘job done’ bin. In my view that would be a big mistake.

Now is the time for someone, perhaps the Institute of Physics, NfER, Nuffield or Gatsby to consider a research project that looks at the pipeline of physics teachers from school to school, and notably from university to teaching. Do different courses produce different numbers of teachers of physics that stay in the profession, and become the leaders of tomorrow or just provide short-term additions to the teaching stock. How important is a middle leadership cadre?

 Mapping these outcomes both geographically and as between public and private schools, and within the public sector as between 11-16; 11-18 and post-16 institutions might create an understanding that could then lead to a debate about how every child could access high quality physics teaching on a regular basis up to Level 3.

With the improvement in mathematics in schools over recent years, there should be the possibility of increasing interest in physics, especially amongst girls. The percentage of girls taking physics is still lamentably low. This is despite 30 years of programmes such as WISE. How far has the lack of management of the scare resource that is teachers of physics held back the encouragement of more girls to study the subject?

Teaching has always looked to be a profession where there is basic pay equality. That’s fine when there aren’t shortages, but there have always been incentives and rewards from golden hellos to additional payments for working in challenging schools. What incentives work to keep teachers of physics in the profession. Is it non-pay matters, such as not having to teach ‘all sciences’ or some mathematics that is as important as pay?

If gender is an issue, what about ethnicity: of both teachers and those that study physics at school? Then there is the issue of what percentage of pupils on free school meals have access to high quality physics teaching? Is it different from those small numbers on free school melas in schools in affluent areas, compared with schools where a large percentage of pupils are on free school meals. In the latter schools, attracting a physics teacher means access for some pupils. In the former, even if there is a physics teacher do the pupils on free school meals have access to physics?

And what about pupils with SEND? What is their access to physics teaching like?

Physics could be a template for other subjects to ask the questions about, ‘what can we do to ensure we have the best system for preparing teachers, recruiting them into schools, and ensuring that they stay in the profession.’ The alternative is that we could carry on as before, and rely upon market forces to provide the Nobel Prize winner of the future.

Numbers granted teaching awards

In a previous post I looked at the prohibition from teaching work of the Teaching Regulation Agency (TRA). However, that is only a part of the work of the Agency. The other main task is to maintain the register of qualified teachers, and to grant admittance to the register. There are two main routes to registration. Obtaining QTS in England via one of the several routes available, including the assessment only route, or to seek registration for a teaching qualification awarded overseas. Various governments at Westminster have approved QTS for teachers from certain countries with acceptable teaching qualifications.

The numbers admitted via the various routes in recent years is shown in the table.

All routes42,24441,92835,29829,595

Source: Teaching Regulation Agency Annual Report and Accounts 2024-25

Those granted QTS, especially through the ITT routes in England, may not enter service in schools where QTS is a requirement. They may choose to work in the private school sector or those post-16 establishments where QTS is not a requirement. They may also move abroad. On the other hand, those granted QTS by the assessment only route and by converting teaching qualifications from outside of England are highly likely to be either working or expecting to work in a school where QTS is required for a teacher to be paid on the Qualified Teacher Scale.

Schools have aways been able to employ unqualified teachers, once called instructors, either where no qualified teacher was available or where the law did not require them to employ qualified teachers, as in some academies and free schools. That latter exemption may be changed by the current parliamentary Bill once it becomes law.

The decline in ITT registrations is partly down to reductions in the primary ITT numbers. These have declined to meet the reduced need for teachers due to the decline in the birthrate, but the fall in registrations also highlights the ITT recruitment crisis of the years immediately post the covid pandemic.  Hopefully, the number of registrations will increase over the next few years as targets should once again be met in many secondary subjects.

Where did overseas teacher applying for QTS apply from?

The response to both a change in the rules regarding overseas trained teachers, and the evidence of a teacher shortage in England, produced a spike in applications in 2023/24 to register as qualified teachers in England from two West African countries, Ghana and Nigeria. Following the exit from the EU, numbers from most EU countries are now very low, amounting to less than 300 in 2024/25, of which 74 applications were from teachers trained in Spain.

Of the countries with the largest number of applications in 2023/24, 1,197 teachers from Ghana; 723 from Hong Kong; 550 from India; 1,309 from Nigeria and 235 from the USA resulted in an award.

Of course, granting an award did not mean that a visa would also be granted, but without these teachers many schools would have found staffing their schools even more of an issue that it actually was in September 2024.

Ethnicity issues remain for new teachers

Data published by the DfE for the 2023/24 postgraduate cohort of trainees achieving QTS (Qualified Teacher Status) showed that differences still remain in regard of entry into the teaching profession between different ethnic groups on two counts. Firstly, the percentage trainees achieving QTS, and secondly, the percentage employed in State-Funded schools.

White16,08215,04811,5701,034

Initial teacher training performance profiles, Academic year 2023/24 – Explore education statistics – GOV.UK

The outcomes were more favourable for the dominant White group. 94% of this group achieved QTS, compared with 93% for the Black and Mixed Group’s trainees and 93% from the Asian Group.

Teachers from the White group were also more likely to be working in a State-Funded school by the time the data was collected. 77% the White Group that had achieved QTS were teaching in a State-Funded school. This compared with 75% of the Mixed and Multiple ethnic groups; 74% of the black Group and just 69% of the Asian group.

Despite the number of teachers from the Asian group not working in State-Funded schools, this group still accounted for 12% of entrants. The black group accounted for 5% of entrants and Mixed and Other ethnic Groups together made up another 6% of entrants. The White group, of some 11,570 teachers, accounted for 76% of entrants. 

Sadly, it isn’t possible to track the whole journey from application to train as a teacher through to working as a teacher with QTS for each ethnic group. It is also not possible to see whether certain routes are more or less favourable to certain ethnic groups. Both those sets of data would help illuminate possible areas of concern within the process of how graduates become a teacher.

The DfE has also included some experimental regional data about outcomes that would also be useful to see by ethnic groups because, historically, the Asian and black groups applicants and trainees have tended to be concentrated in specific urban areas.

The DfE data suggested that fewer trainees achieving QTS were employed in State-Funded schools in the north of England than the south. The region with the highest percentage employed was the East of England, were 82% of those achieving QTS were employed in a State-Funded school. 

Another indicator where there are no published data on trainees by ethnic groups are in respect of new graduate and career changers. For the purpose of the employment data for those with QTS, the DfE splits the trainees into two groups; those under 25 that might be assumed to be mostly new graduates and those over 25 that will predominantly be career changers. Those in the over-25 group were less likely to achieve QTS, but there was no difference among those with QTS in terms of the percentage working in State-Funded schools.

Less than 400 teachers of physics entered service in 2023/24

As a result of the latest data from the DfE, it is now possible to start to see the consequences arising from the collapse in ITT recruitment to secondary courses in 2023/24.

It is interesting to compare the turnaround from the improvement in recruitment brought about by the covid epidemic with the poor recruitment figures for just three years later.

The reduction in numbers achieving QTS (Qualified Teacher Status) from 30,706 in 2002/21 to 21,210 in 2023/24, a reduction of some 8,500, or more than a quarter in just three years, goes some way to demonstrate the depth of the problems with recruitment schools faced in September 2024 and even more so in January 2025.

Hopefully, these numbers represent the lowest point for secondary trainee numbers over the next few years, after adjusting for the changes in targets that result from falling rolls in schools.

The data on the percentage achieving QTS might suggest that when it is difficult to recruit trainees, more marginal candidates are offered a place by training providers, and, as a result, the percentage not achieving QTS increases.

Because the DfE only records those with QTS teaching in a State-Funded ‘school’ it does not count those employed in a Sixth Form College or other further education college and, does not count any teachers from the cohort with QTS working in the private school sector. This latter omission might account for why only 49% of those trained to teach Classics were teaching in a State-Funded school.

It is interesting to note that the percentage of those trained to teach physics teaching in a State-Funded school was the same as the overall average, at 77%. However, that meant that there were only 373 new physic teacher entrants into State-Funded secondary schools from this cohort. It would be interesting to know the routes these 373 took before taking up their initial posts? How many of these 373 were from the PG Salaried High Potential ITT route? (Better known as Teach First).

The relatively small percentage of physical education trainees recorded as working in State-Funded schools may well be a result of the numbers recruited into training compared with the target.

Where trainees are required to pay a tuition fee for a course, what responsibility does the government and the course provider have to the trainee to ensure that there are not way too many trainees for the number of vacancies likely to arise? If this means that the student debt is less likely to be recovered, is this a waste of public money?

In a future post I will explore some other aspects of this dataset.

It’s a funny old world

On the day when nurses look as if they will join resident doctors in demanding more pay, figures about applications from graduates to train as a secondary school teacher hit decade high levels, even after removing the degree apprenticeship numbers from the totals. This month, according to DfE data, 58,880 candidates have submitted one or more applications to train as a teacher. This compares with 46,696 list July and 45,000 in 2108, before the pandemic. Initial teacher training application statistics for courses starting in the 2025 to 2026 academic year – Apply for teacher training – GOV.UK

This July, there were 36,283 candidates applying to train as a secondary school teacher, compared with 17,997 wanting to train as a primary school teacher.

By comparison in July 2018, 26,060 women had applied, whereas in July 2025 that had increased to 31,439. However, applications from men had increased from 12,680 in 2018 to 18,904 this July

Traditional higher education and SCITT courses still account for the bulk of the routes into teaching selected by candidates. However, candidate numbers on traditional salaried routes were down this July, from 8,927 to 7,636, but that may be partly the 7,332 candidates that have applied for the Postgraduate teaching apprenticeship route, up from 6,433 last July.

The new Teacher Degree Apprenticeship route that has attracted 1,079 candidates so far this year. This is a new route and, presumably isn’t open to graduates.

Although applicant numbers from the ‘rest of the world’ group are down this July, from 9,586 in July 2024, to 8,563 this July – this number still represents nearly 20% of all candidates.

Some subjects, including art, physical education, physics, mathematics and computing have recorded their highest level of ‘offers’ this year since the 2013/14 recruitment round. How many are multiple offers or from candidate’s not able to fulfil visa requirements won’t be known until the courses start in just over a month’s time.  Interestingly, offers for English courses are below the number of offers made in July 2024.

Despite the significant increase in candidate numbers, some subjects will not hit their targets set by the DfE this year. Subjects most likely to miss their targets are business studies, drama, religious education, music and design and technology. In English, it looks touch and go at this moment in time as to whether or not the target will be hit.

In some subjects, such as physical education, where the target is 725, there is a risk of a significant overshoot in offers. Such a situation might leave large numbers of trainees with additional debt and little chance of a teaching post in England next summer. The DfE will need to be alert to this issue, especially if the growth in ‘AI’ changes the labour market for those with degrees in physics and mathematics, so as to make teaching look like an interesting career at current salary levels.

It would be a funny old world if incentives to train as a teacher had to be switched from mathematics and the sciences to English and the arts.

The crisis in physics teaching

NfER has published some interesting research about the distribution of physics teachers A widespread lack of specialist physics teachers persists due to recruitment and retention challenges – NFER The most alarming statistic in the report is that 26% of state-funded secondary schools that responded to the School workforce Census had no qualified physics specialist in their science department.

However, there is a caveat to making too much of the data. This is because it is taken from the School Workforce Census. As this is a self-reporting census, the data must be regarded with a degree of caution, as there could be some under-reporting.

As the School Workforce Survey is conducted by the DfE each autumn term, it should have a degree of reliability. However, the NfER report only contains data from 2,296 of the 3,456 state-funded secondary schools in England.

Even so, assuming all the remaining schools have at least one qualified teacher of physics that would mean at least 12% of schools were without a qualified teacher of physics, and more than a third of schools (36%) has either no teacher or only one teacher.

Now some of these schools are 11-16 schools, and a few the remaining middle schools classified as secondary schools. These schools don’t need a teacher for ‘A’ level courses. But who is teaching the GSCE physics courses, and how many pupils from these schools go on to study physics at ‘A’ level?

For the 11-8 schools with no qualified teacher of physics, what arrangements are being made for pupils that want to study the subject at ‘A’ level. If it is matter of having to change school, then what are the costs to the pupils and their families. This is another example of where transport costs may affect choice of courses post-GCSE.

Do schools support each other? This was easy when all schools were maintained schools. In the 1960s, the local girls’ school where I lived could not support Chemistry ‘A’ level, and those girls wanting to study the subject joined the ‘A’ level class at the school I attended. This must be more challenging to arrange these days with competing Multi Academy Trusts.

Interestingly, if you add up all the qualified teachers in the table in the NfER survey it amounts to more than 3,500 qualified teachers of physics: enough for one for every school. However, our distribution system for teachers is based upon open market principles, with teachers free to apply for any post, and teach where they like. Is this the best system for the education of all children, if it means that some are deprived the opportunity to study subjects such as physics because there is no qualified teacher?

Hopefully, the present position marks the bottom of the staffing cycle, and improved interest in teaching, as reported in this blog and on my LinkedIn pages, means more trainees with emerge into the labour market over the next few years.  The issue then will be how to create teaching posts for them. Wil schools be required to either redeploy an existing member of staff or make them redundant? Those schools with falling rolls and a stable staff might find the former difficult. What is needed is a national plan for physics, and perhaps other subjects where there are teacher shortages. But, sadly, I doubt we will see such a radical idea from this government.

Schooling and the relentless march of technology

Teachers will not have been happy to read of employers paying workers the same money for a four day week where they used to earn for working for five days. I assume that productivity or output or company profits remained the same, so the company could afford to be this generous while not upsetting its shareholders.

Unhappy teachers might reflect on two things. As technology improves, so workers can produce the same output in less time: think handwriting letters, then dictating them to someone that then typed them and then word processing them. Of course, rewarding those workers that benefit could come at a cost to productivity and growth for all. Why not continue the five day week and produce more?  

My parent’s generation worked a five and a half day week, with Saturday working being commonplace. Teachers have not benefitted from these changes, partly because their job has largely been unaffected by significant changes in technology that improve productivity. Now this may be because teaching is a public sector good and there is no profit element to spur on change for the benefit of both owners and workers.

As we can see from the imposition of VAT on private schools, the reaction of many was to increase fees, not to improve productivity, even by adding one pupil per class to their already small classes – special schools excepted – and absorb the cost.

However, it is the second implication of technological change and its effect on teachers and society that worries me just as much. Here’s another example. Driverless vehicles will become mainstream. Sure, there will be accidents, as there were when railways and aeroplanes were being developed. And these days society knows more about preventing those sorts of accidents happening to the same degree – think of the space race and the ratio of deaths to achievements. But, what of the many drivers that will join the ranks of porters, stenographers, bank tellers, coal miners and many others whose jobs have disappeared. Will technology create another set of new jobs for those with skills to do the jobs of today?

What are the implications for schools and their role in society? This should be the key question at the Festival of Education? What steps are politicians and the think tanks that provide them with research doing to consider the role of schooling in the second half of this century. After all, those that start school at age five this coming September will likely not retire on a state pension until 2090 or possibly even later.

Primary schooling with the acquisition of vocabulary and the social skills of living together in communities will become even more important than it has been seen by politicians in the past. Secondary education and subject skills might even become less important.  The recently announced government inquiry into White working-class kids might want to think about this issue during their deliberations. Solutions for the problems of the past won’t help the kids facing an uncertain future.

Falling rolls

The projections for pupil numbers up to 2030 were issued by the DfE this week.

At the same time the Office for National Statistics (ONS) looked at the likely size of + the school population  aged 5-15 National population projections – Office for National Statistics both have implications for the demand for teachers in England. This data can help determine how many teachers will be needed to staff schools and the attractiveness of teaching as a career.

The DfE concluded the following for the remainder of this decade;

State-funded nursery & primary schools

  • The overall pupil population in these school types is projected to be 4,205,000 in 2030. This is 300,000 (6.7%) lower than the actual population in 2025 (4,505,000).
  • The revised projection for 2028 of 4,319,000 pupils represents a 5.4% fall from 2024; this is 38,000 lower than the previous forecast, as last year’s projection showed a 4.5% fall over the same period.
  • The nursery & primary population is therefore still projected to drop and is doing so at a faster rate than previously projected.

State-funded secondary schools

  • The secondary school population is projected to be 3,135,000 in 2030. This is 97,000 lower than the actual school population reported in the 2025 school census of 3,232,000.
  • The revised projection for 2028 of 3,208,000 secondary pupils represents a 0.8% fall from 2024, and is 55,000 (1.7%) lower than last year’s projections which reverses the previously projected 0.9% increase over the same period. 
  • The pattern of change in the secondary school population seems to indicate that it plateaued between 2024 and 2025, will remain at a similar level until 2026, and is then projected to start declining slowly. This suggested plateau is earlier than the peak in 2026 projected last year but will be subject to change if pupil numbers bounce back, fluctuate, or continue to plateau in future years.
  • The actual number of secondary school pupils in 2025 fell slightly as more pupils moved out of the secondary phase than moved in. Changing historical birth rates and trends in net migration are likely driving factors. National pupil projections, Reporting year 2025 – Explore education statistics – GOV.UK 

According to the ONS projections, there are expected to be fewer children in the UK by the middle of both 2032 and 2047, compared with the middle of 2022. The ONS have based this on a view that the assumed fertility rates in the 2020s and 2030s will be even lower than those around 2001, when UK fertility reached a record low.

By mid-2032, the number of children (those aged from 0 to 15 years) is projected by the ONS to have decreased by 797,000 (a fall of 6.4%), from 12.4 million to 11.6 million. By mid-2047, the number of children is projected to remain around the mid-2032 levels. Of course, if the birth rate changes, these numbers could be either too high or an underestimate. Either way planners are no expecting the need for more teachers due to changes in the birth rate.

However, these numbers are just assumptions, and don’t take into account other changes in the numbers in the 0-15 age groups resulting from any net balance once both emigration and immigration have been taken into account.

Other factors, such as the departure rate from teaching, due either to the popularity of teaching or the availability of alternative employment opportunities, as well as the age-profile of the profession and the number of teachers retiring can affect the demand for teachers. Policy changes concerning how children are taught can also affect the demand for teachers. How will AI and attitudes to issues such as home schooling are two imponderables that might affect the demand for teachers.

These days, as well as the traditional modelling, the DfE has access to up to the minute data on vacancy rates for teachers, and how posts are filled. This new data, allied to more traditional methods of estimating the demand for teachers, should help to ensure teacher unemployment can be kept to a minimum. After all, there is little point in spending money training teachers only for them to be both burdened with debt and unable to find a teaching post.
