Law of unintended consequences

The news that Prof Dame Jocelyn Bell Burnell has been awarded a Breakthrough Prize for the discovery of radio pulsars is long overdue recognition for her part in this research. Her decision to use the award to donate her £2.3m winnings is a noble gesture, to be applauded and hopefully recognised in other ways by a grateful nation.

The money will go to fund women, under-represented ethnic minority and refugee students to become physics researchers. Such a use for a scheme, to be administered by the Institute of Physics, is also an inspiring use of the cash from the award, especially if it attracts additional funds from other sources, since by itself even £2.3 million won’t go very far these days. If it generates £150,000 of annual interest at current rates it will be doing well.

So a good idea but, if the scheme is to fund undergraduates in Physics to conduct graduate research that they currently cannot afford to undertake, who will be the loser. Keen readers of this blog can anticipate what will come next. Assuming the stock of undergraduates remains the same, at least in the short-term, and the number undertaking research increases, rather than just substituting under-represented groups for existing entrants into research, then some other post-degree employment routes will find a reduction in the supply of Physics graduates. Might this affect the numbers going into teaching? Of course, if the pool of research places remains the same and we substitute under-represented groups for those currently taking the places that won’t be the outcome.

Much may come down to how the Institute of Physics designs the scheme and works with providers of research places to implement it, especially in the early days of the scheme.

There is a need for more undergraduate places in Physics, again to facilitate more entrants from under-represented groups in society, and from those where the teaching they receive isn’t at the highest level.

The DfE calculates that the state-funded school sector will need around 1300-1350 new entrants in each of the next few years, to maintain the required teaching stock of teachers of Physics. Fortunately, the age distribution of the present Physics teacher workforce seems unlikely to create a retirement boom anytime soon.

However, the last few years have seen insufficient new entrants to meet the DfE number for the expressed need. As a result, any further diversion away from teaching and into research would potentially affect some schools ability to recruit teachers of Physics, even if only for a few years, if these researchers then chose to enter teaching at a later date. If they didn’t, having been provided the opportunity to conduct research, then there would be further pressure on teacher supply. Of course, a recession either resulting for problems in emerging markets of because of Breixt might create a new cadre of potential Physics teachers. However, is that a risk worth taking? The DfE could try to import Physics teachers, but it is not clear how well such schemes have progressed in the recent past. Creating more university undergraduate places linked to teaching as a career might well be worth exploring further. The only other suggestion on the table seems to be paying Physics teachers more than those in subjects where there is no shortage. I discussed that idea in an earlier post.

 

Possible improvements in Key Stage 2 outcomes?

The DfE has today published the provisional Key Stage 2 assessments. There are some in the Liberal Democrats that would do away with these measures. I think there is a need to make them less stressful for both pupils and teachers but equally there is a need to demonstrate an informed understanding of how our education system is performing. The data and DfE’s comments can be found at: https://www.gov.uk/government/statistics/national-curriculum-assessments-key-stage-2-2018-provisional The data are provisional at this stage. In December more finalised data will be published. However, I suspect the overall figures will remain broadly the same.

One interesting observation in the DfE’s comments on page 18 of their analysis is that local authorities with lower attainment levels tended to see the biggest changes in attainment since 2017. This is both good news and not unexpected. If 80% of children are reaching the expected standard, then the other 20% may require significant resources to help them achieve what is expected. Whereas, where it is less than 60% of pupils there are probably easier gains. It would be interesting when the final figures appear to see how pupils receiving the Pupil Premium have fared in term s of improvements.

Cartographers might question the selection of grade boundaries used in the DfE’s map as they provide a representational view that focuses on local authorities in the middle of the range. (Incidentally, the map is difficult to read as far as local authority names are concerned and could be improved). There isn’t anything wrong with this approach, but the range between the bottom of the light blue and the top of the darker blue is only six points, whereas the range in the outliers is much greater. Tough on a local authority with a score of 61 such as West Sussex that is the same colour as Peterborough with 52%. Incidentally, I am not clear why the scale starts at 42%? But, perhaps the DfE aren’t using the data from Table L1 for the map. They don’t provide a link to the data.

As in the past, girls generally outperform boys, except in mathematics, where in the scaled score, boys have a higher score than girls, as is also the case for those performing at the higher ability level. For detailed data about other characteristics we must wait until December. The data for middle schools can largely be regarded as being based upon so few schools as not to be really representative, unless you live in an area with these schools and might want to question their future.

The data won’t help the Humanists that want to see an end to faith schools as, the more specific the faith, the better the outcome in their schools with; Jewish, Muslim and Sikh schools all performing better than other schools and especially better than schools with no religious character.  This may well tell us more about parental choice and support by parents that make a positive choice of school than about anything else.

Finally, as the DfE helpfully points out, attainment in all of reading, writing and maths is not directly comparable to previous years because of changes to writing TA frameworks. That doesn’t stop the DfE producing some comparisons.

Welcome for BERA Bites series

BERA, The British Educational Research Association today publishes the second in its series of BERA Bites https://www.bera.ac.uk/researchers-resources/publications/issue-2-educational-leadership-are-our-schools-fit-for-the-future

The BERA Bites series presents selected articles from the BERA Blog on key topics in education, presented in an easily printable and digestible format to serve as teaching and learning resources for students and professionals in education. Each collection features an introduction by editors with expertise in the field, and each article includes questions for discussion, composed by the authors, prompting readers to further explore the ideas and arguments put forward in the original articles.

This second BERA Bite is especially of interest to this blog as it contains a post from almost exactly two years ago. The post appeared on this blog on the 7th September 2016 and you can read it be either downloading the BERA bits of searching the archive on this blog for September 2016. The post was entitledRecruitment, Retention and Region The three ‘R’s’ challenging school performance in England’.

I am grateful to BERA for putting this series together. It is a new form of peer review to have blog posts reviewed as well as more formal articles and the BITES series can become useful teaching aids for particular topics if kept regularly up to date. The issue of relevance is key. I turned to writing a blog, partly because for 11 years I wrote a variety of weekly columns for the TES and partly because, in a fast moving area such as the labour marker for teachers, writing academic articles is fine and dandy, but by the time they appear they are often only of historical interest in terms of policy development.

This is best seen in the series of posts on this blog during August 2013, when I wrote a post on the 7th August predicting a teacher supply crisis in London starting in 2014. The subsequent posts show the government reacted to my conclusions. Had I written an article for an academic journal about a possible teacher supply crisis and submitted it in August 2013, some reviewers might have rejected it as lacking sufficient evidence and, even if sufficiently articulate and scholarly, neither outcomes I can guarantee to produce, it would have been sometime in 2014 before it saw the light of day.

This is not to argue for the demise of academic journals, their place is firmly established in the academic discourses but to welcome the move BERA and others are making to recognise that some areas of education policy move at a different pace to others and may need different forms of discourse and that there is a need for teaching materials prompting readers to further explore the discussions put forward in the original articles.

So, please do read the BERA Bites both 1 & 2 and let BERA know what you think of the new series. If you are not a BERA member, but a regular reader of this blog, then you might want to consider whether it would be worth joining BERA, even if only for the access to the range research and information it provides to those interested in education.

Bulk buying back in vogue

When I was a young teacher in London there was a large central buying organisation for schools, called something like Greater London Supplies. I recall that they had a big depot at Tottenham Hale in north London. Purchasing basic supplies on behalf of large numbers of schools made good business sense, even to the most socialist of Labour councils. However, it didn’t make sense to the Thatcher government that believed market competition at a school level was the way forward.

Reading the DfE’s recent announcement on procurement and helping schools with costs, suggests that this is yet another move back in the direction of levering the purchasing power of schools as a combined unit, rather than expecting them to operate as individual business sites. How long will it be before Ofsted is asked to include in their inspection report whether a school is making full use effective purchasing decisions to target as much cash as possible on teaching and learning?

TeachVac, the free vacancy site for schools and teachers, www.teachvac.co.uk  where I am chair of the board, doesn’t yet feature in the DfE list. I am sure that they will find a good reason not to list it, as they don’t yet list any vacancy advertising services, whether they are either paid for services like all the others or free like TeachVac and their own nascent service. Maybe they don’t want competition?

The government’s actions in driving down costs aren’t completely risk free. After all, if prices are driven down too far then suppliers will exit the market and leave just one monopoly provider. At that point, it becomes an issue as to whether the State should regulate the provision of the service or actually take over the running.

As I have suggested in previous posts on this topic, once prices have been reduced by increasing efficiency then it can become very difficult to make a profit. Then there is also the reason why local decision-making was favoured by many: the speed of service delivery. A central maintenance contract may be cheaper, but what is the true cost of waiting several days for a window to be replaced or a leaking toilet mended?

I am sure that there is a unit within the DfE thinking of other areas where schools can either save money or increase their incomes without putting more pressure on parents. They might want to ensure deals there are good deals on school uniforms and sports kit and make schools explain why they are requiring a uniform that is more expensive than the average. Tradition, would not be a good enough answer.

My own suggestion for research is, as mentioned before, school playgrounds. They must be the least used piece of real estate in the country. I don’t suggest they are done away with, as when needed they perform a vital function, but what can we do with them for the other 99% of the year? More all-weather community pitches; a source of generating renewable energy; even vegetable growing spaces areas with a playground on top.

We are spending millions on research into driverless cars; how about a couple of million for more effective playground spaces?

 

 

Will teacher supply worsen in 2019?

The problem with reports like the one published by the Education Policy Institute (EPI) yesterday is that they don’t help policy makers very much. Headlines of a teacher shortage are nothing new and looking at the position in 2016 doesn’t tell anyone what is happening now and will happen in the 2019 labour market. As I said in yesterday’s blog post, knowing where the hot spots are is a useful piece of extra knowledge, but is that really what the leading think tank on education sees as the best use of its resources?

I promised in my blog about the UCAS data, also published yesterday, to look at trends in August offer numbers. The following table looks at key subjects for this August and the previous two years, as well as the change between 2016 and 2018.

Source: UCAS monthly reports, August 2016, 2017 and 2018.

Despite the upward trend in pupil numbers, the trend in the number of offers has been downwards over the past two years. This suggests an even greater ‘crisis’ for schools in the 2019 labour market across some subjects, although the science numbers must be treated with  degree of discretion until the census appears in November due to a change in the method of recording offers by UCAS this year for applications. I doubt that Teach First will be riding to the rescue this year, although we must wait until November to find out their recruitment figures.

We don’t need more geography and history teachers, or last not as many more as have been recruited over the past two years. These offers don’t relate to the Teacher Supply model estimates of numbers needed, but many subjects will again fall short of that number. We will analyses the shortfall when the census appears. For a look at recent years, it is worth consulting the School Teachers’ Review Body’s latest report issued in July or you could look back through the posts on this blog. However, it is also worth remembering that EPI only looked at new entrants and didn’t fully factor in what might be happening with returner numbers, something NfER have been considering in their studies.

Might it be time to revive the posts of regional recruitment managers, used by the Labour government nearly 20 years ago during a previous recruitment crisis? Alternatively, do we need to make the most of the resources available by moving away from a free market? If it is acceptable for academy trusts to move teachers between schools should it not be acceptable to do so on a more national scale?

 

Mixed messages on trainee numbers

The UCAS data on the numbers applying for and accepted for postgraduate teacher preparation courses starting this autumn were published earlier today. Usually, these numbers represent a good guide to the actual numbers likely to be recorded in the DfE’s ITT census, taken shortly after courses have commenced. This year, a change in the manner of how ‘conditional place’ and’ holding offer’ numbers are recorded for applications, but not applicants, compared to previous years has led to a risk that the data may be less reliable as a guide, especially in the three science subjects.

For secondary numbers, the outcome overall looks as if it will be similar to last year, with some subjects doing slightly better than last year and other slightly worse. Overall applicant numbers are very similar to this point last year, just 850 or so down on last year for England; a decline of around two per cent. Hopefully, this means the bottom of the cycle has been reached.

Although there has been a significant recovery in applications for those under the age of 25, numbers in these age groups are still down on last year. The loss is balanced by increases in applications from those over the age of 30. However, these older applicants have not been ‘placed’ to the same extent as last year. But, there are larger numbers in the ‘conditional placed’ and ‘holding offer’ categories that are still in use for applicant numbers, even though they are not included in the applications table for secondary subjects.

Interestingly, it is a late increase in the number of women applicants that has boosted the total. The number of male applicants, at 12,570 overall, is 670 down on the 2017 August figure.

Total number offered a place with or without conditions has increased from 67% of total applicants to 72% this year. No doubt the Minister’s views on the subject, expressed in a speech earlier in the year, may have boosted offer rates.

After allowing for the fact that application numbers are expressed differently to last year, the number likely to be recruited to primary sector courses appears possibly to be around 1,500 fewer than last year according to the numbers in table B.8. This is a lot better than seemed likely the case in the early months of 2018. However, these is a difference of several thousand between this table and the numbers cited for primary course types in Table B.11. Using Table B.8 for secondary, the recorded number of applications has increased from 64,760 to 66,770, between August 2017 and August 2018. However, numbers offered places may be lower than in 2017.

School Direct offers of all types seem to be down, when compared with August 2017, in both the primary and secondary sectors, with just 990 offers for Secondary School Direct Salaried courses compared with 1,130 offers of all types for these places last August. If confirmed in the ITT census this, further reduction will present a real challenge for the future of this Scheme, celebrated by Michael Gove when Secretary of State for Education as the future route for training teachers.

Next month there will be the end of cycle preliminary figures and then nothing until the start of the 2019 recruitment round in November.

 

How has teacher expertise changed recently?

Following on from the previous post about today’s EPI study, I thought that I would update the Table from the Migration Advisory Committee report on teacher expertise, with the findings of the 2016 and 2017 School Workforce Census.

Now, there is a teacher shortage and this blog had a spot of bother back in the summer of 2014 when it first revealed a possible teacher supply crisis. It is also accepted that teacher shortages overall and of those most appropriately qualified are likely to be most significant in schools with higher levels of deprivation than in areas of affluence. It is also worth recalling that pupil numbers in secondary schools were falling in the years up to 2016, and that budget pressures can also play a part in determining class sizes as well as availability of qualified teachers.

In further posts today, I will examine the UCAS data both for August this year, as a predictor of the 2019 supply side of the teacher labour market and then consider how 2019 compares with the previous two years for August’s in relation to the expectation of trainee numbers.

There is room for a genuine debate about how the teacher stock can be best used to provide the best outcomes for all pupils. But, that may require a degree of intervention by government not acceptable in a capitalist economy: hence, presumably, EPI’s suggestion of market based solutions. The failure of the attempts by the coalition government, of which David Laws the head of EPI was a serving Minister in the DfE, to create either a National Teaching Service or a method of providing head teachers to challenging schools, shows how complicated the labour market in teaching can be when no one body has overall control and budgets are allocated to individual schools. But, that debate has been well-rehearsed already on this blog.

There is also the issue of where increasing recruitment into training would mean more teacher unemployment? Can the system absorb more trainees? Evidence from TeachVac www.teachvac.co.uk suggest that in mathematics that might be a challenge to employ increased numbers of trainees as there are unlikely to be many suppressed vacancies and increased supply might not be met be increased demand, unless those already teaching maths and regarded as under-qualified were either redeployed or made redundant in some way. Could making someone redundant to replace them with someone doing the same job, but with different qualifications, see some employment law challenges?

Fortunately, rising pupil numbers offers a way out of that dilemma, as does harnessing modern technology effectively to assist the teaching and learning process.

Pay physics teachers more than history teachers?

The research report published today by the Education Policy institute (EPI) is an interesting addition to the cannon of literature on the issue of teacher shortages.  https://epi.org.uk/wp-content/uploads/2018/08/EPI-Teacher-Labour-Market_2018.pdf The major new component in ‘The Teacher Labour Market in England shortages, subject expertise and incentives’ is the consideration of where shortages are located on a local authority by local authority basis. The data comes from the 2016 School Workforce Census of 2016, so is now two years out of date.

Much of the basic issues around shortages have been covered by the Migration Advisory Committee, the School Teachers’ Review Body, the Education Select Committee, the National Audit Office and the range of publications from the DfE including their index of teacher shortages as well as previous publications from EPI. In that respect, the lack of a bibliography is something of a shortcoming in this report.

Indeed, missing from any analysis of shortages in the EPI report is a discussion of the relationship between the training market and the demand for teachers by schools. Are we training teachers where they are needed or are we, as a nation, training them where they are not needed? The supply of mathematics teachers is a case in point. As this blog has pointed out, there are more trainees in maths than in English, but the number of vacancies is roughly the same since the amount of curriculum time for each subject is roughly the same.

A quick look at TeachVac’s percentage of advertisements in maths and English for 2018 in just the South East region is revealing in their shares of the overall total.

Eng % maths%
Southampton 15% 21%
Reading 17% 19%
Hampshire 18% 16%
Slough 13% 16%
East Sussex 16% 15%
Medway 15% 15%
Brighton and Hove 11% 15%
Kent 11% 14%
Oxfordshire 9% 14%
Isle of Wight 14% 14%
Windsor and Maidenhead 8% 14%
Buckinghamshire 15% 14%
Milton Keynes 10% 12%
Surrey 10% 11%
Bracknell Forest 12% 11%
West Berkshire 16% 10%
West Sussex 17% 9%
Wokingham 21% 9%
Portsmouth 18% 8%
All South East 13% 13%

 

Now these numbers haven’t been corrected for re-advertisements, so there is some over-estimates.

The EPI conclusion that in many areas schools with a greater degree of deprivation among their school population have fewer teachers with degrees most closely connected to shortage subjects, is revealing, but not surprising. This was a tenant of the former Secondary School Curriculum and Staffing Surveys that the Department for Education and its predecessors used to use before the School Workforce Census to measure expertise among the workforce. How to teach Physics at ‘A’ level in schools where there is no teacher with a Physics degree is a real challenge for a fractured education system, where cooperation between schools is not encouraged. But, it is not a revelation. Indeed, the EPI study might have benefitted from looking at changes over time in the use of under-qualified teachers as the Migration Advisory Committee achieved in Table 4.19 of their 2017 Report.

Finally, the EPI solutions proposed   provide a real sense of deja vue. Salary supplements for working in challenging schools seems very like the ‘Schools of exceptional difficulty’ payments of the Heath government in the 1970s and schools can already pay recruitment and retention allowances to teachers in shortage subjects, but don’t seem to do so. However, they seem more willing to pay heads of department in shortage subjects more either through higher TLRs or offering posts on the Leadership Scale. This is an area EPI might like to investigate at some point in the future.

EPI did not consider the DfE’s CPD programme in mathematics that is trying to improve the qualifications of those already teaching the subject. Such an approach can be more helpful than salary supplements that pay teachers different amounts for performing the same task. There would need to be an index of shortages and although it would be headed by Physics – where the country just doesn’t produce enough graduates – business studies would probably come next; a subject not mentioned by EPI.

 

 

 

 

Crime and a lack of learning

During the summer, the Ministry of Justice published a report called ‘A Sporting Chance: An Independent Review of Sport in Youth and Adult Prisons’ by Professor Rosie Meek. You can access the report at: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/733184/a-sporting-chance-an-independent-review-sport-in-justice.pdf

I have only just caught up with reading the report, but what struck me forcibly was the following paragraph:

Those in custody are likely to have disrupted and negative experiences of learning prior to incarceration, and to lack confidence in their learning abilities. A recent data-matching exercise between the Ministry of Justice and Department for Education* showed that of the young people sentenced to custody in 2014, 90% have a previous record of persistent absence from school and almost a quarter of those sentenced to less than 12 months in custody have been permanently excluded from school. In terms of achievement, only 1% of those sentenced to less than 12 months achieved 5 or more GCSES (or equivalents) graded A* – C including English and Maths. Furthermore, illustrating the over-representation of people who have been in both the care system and the criminal justice system, 31% of those sentenced to custody for 12 months or longer, and 27% of those sentenced to custody for less than 12 months had been in the care of a local authority.

* MoJ/DfE (2016). Understanding the Educational Background of Young Offenders: Joint Experimental Statistical Report from the Ministry of Justice and Department for Education.

There is a powerful message here to schools that don’t have a credible policy for dealing with their challenging pupils, other than excluding them from school. We need to work together for the good of society. The DfE needs to ensure there is a coherent curriculum, including English and mathematics, but not necessarily the rest of the English Baccalaureate for pupils that can use these subjects to retain their place as learners. There is a space for sport and other non-classroom based subjects in the curriculum.

The message that education is for all also needs to be firmly inculcated at the start of all teacher preparation courses. Perhaps the Secretary of State might like to break with tradition and issue a message of hope and encouragement to all starting on their journey to become a teacher this September. With his background on the Education Select Committee and work with the APPG, the Secretary of State is well placed to remind new entrants, and indeed the whole profession, of the need to provide as teachers and school leaders for the needs of all our young people.

Happily, we no longer lock up more than 3,000 under-18s, as was the case a decade ago, but even a thousand is too many. It is clear that finding ways of investing in all our young people can help reduce offending and alienation. As I have said before on this blog, a start could be made by ensuring all young people taken into care do not suffer a break in their education. A place on roll of an education institution within fourteen days of being taken into care should be the requirement for all and schools should be willing to cooperate.

 

Update on head teacher recruitment

Way back at the beginning of May this year, I reported on trends in primary leadership recruitment. The data came from TeachVac www.teachvac.co.uk the free to use recruitment site that costs both schools and teachers nothing to use, and where I am chair of the company.

With a miserably wet day yesterday, I thought I would take a second look at the data for 2018 in the area of primary head teacher recruitment. So far, it I seems to be turning out to be a pretty average year. TeachVac has records of more than 1,200 advertisements for a head teacher, placed by primary schools. Of these, around 22% are re-advertisements placed more than a month after the original advert appeared. In May, I reported some 175 schools had been forced to re-advertise a headship; by last week that number had risen to close to 225.

The number of schools placing multiple re-advertisements, each at least four week apart, had also increased; from 25 recorded in May, to a current number of around 40 schools. This includes one school with an original advert plus four re-advertisements. I do hope each one didn’t come with a separate bill for advertising.

As in the past, schools associated with the various faiths seem to be more likely to have to re-advertise than non-faith schools.  Of course, it might not be the faith aspect that is causing the re-advertisement, although I think that may be part of the issue. Size, geography and type of schools, whether or not it is an academy, for instance, can all play a part.

In the past Roman Catholic run schools in the North West rarely featured in the list of schools challenged when seeking a new head teacher. This year they account for more than 40% of such schools that have re-advertised.

TeachVac could also investigate the effects of other variables such as size of school; ofsted grades and timing of any inspection report along with output measures such as Key Stage results and progress of pupils over time. However, we don’t have the research funds for such analysis at this point in time. Nearly a decade ago, the then National College sponsored an investigation into ‘hard to fill headships’. I am not sure it was ever published, and assume that it is now buried somewhere deep in the archives of Sanctuary Buildings, if it hasn’t already been consigned to the National Archives at Kew.

Overall, the message to chairs of governors, and governing bodies as a whole, remains the same as it always has been. If your head teacher announces that they are leaving, either to retire or to take on a new challenge, the two most likely reasons for a change of headship, then ask three questions; is their someone in the school we could appoint either directly or after some professional development; are there likely to be candidates from within travelling distance of the school; if neither of these can be answered in the affirmative, how are we going to ensure a smooth succession that doesn’t affect the pupils and staff at the school?

There is plenty of good advice out there along with lots of high quality candidates. Hopefully, schools will experience a great term recruiting heads to their vacancies: good luck.
