Retaining teachers in Wales – what do we know?

By Jack Worth and Jennifer Garry

As we have previously reported, government statistics show that retaining working age teachers in England appears to have been getting more difficult, while our latest survey data suggests this trend may now be reversing. Last month the Education Select Committee published a report on teacher recruitment and retention in England, urging the Government to “place greater emphasis on retaining teachers and not just focus on the necessary task of recruiting new teachers”. But what do we know about teachers in Wales?

The number of teachers leaving is fairly stable

Statistics published by the Welsh Government show that the proportion of teachers leaving the profession (excluding those retiring) in Wales has increased very slightly in recent years. Since 2012, the leaving rate has remained at around three per cent per year for both primary and secondary schools.

This finding is in stark contrast to England, where teachers have been leaving the profession (and not retiring) at a higher rate, and where the rate has increased more rapidly in recent years. In 2015, the proportion of teachers leaving the profession in England (7.8% primary, 8.1% secondary) was more than two times higher than in Wales (2.8% primary, 3.2% secondary) at both the primary and secondary level. Our latest survey data shows that the proportion of teachers that are considering leaving the profession fell significantly between autumn 2015 and autumn 2016, which suggests that the retention figures may show an improvement when they are published in July 2018.

However, comparisons between the teaching workforce in England and Wales must be made with caution due to the different methodologies used to collect the data. Unlike the school workforce census in England, there is currently no single collection of individual-level teacher data in Wales. The data published by Stats Wales presents limited information gathered from a range of inconsistent data collections and surveys. Although the data provides an interesting insight into the teaching workforce in Wales, it does not allow scope for detailed analysis and reliable comparisons to be drawn.

England appears to have a higher proportion of teachers leaving the profession than Wales, but the poorer-quality Welsh data may be giving an inconsistent picture

Despite a smaller proportion of teachers leaving in Wales, replacing those that do leave remains important for maintaining the ratio of teachers to pupils in Wales. The Welsh Government’s teacher recruitment statistics show that the majority of vacant roles are being successfully filled. However, between 2011 and 2015, the proportion of positions left vacant increased by three percentage points at primary level and four percentage points at the secondary level.

For primary school vacancies, there has been an average of 20 applications per position advertised in the last five years. Meanwhile secondary school vacancies have received an average of 11 applications per advertised role over the same period.

However, the number of applicants per advertised role has decreased significantly between 2011 and 2015 for both primary and secondary positions, falling from 25 to 16 applicants per vacancy for primary schools and from 15 to nine applicants per vacancy for secondary schools. The decline in the average number of applicants per vacancy suggests that the labour market has got tighter and schools are finding it harder to recruit.

The average number of applicants per advertised post in Wales has been falling

This market tightening, coupled with roles going unfilled despite the large number of applicants, suggests that the quality of applicants may not be wholly suitable to meet schools’ demands. Moreover, the ability to fill vacant positions is likely to vary greatly by subject, area, school or role. While some positions will be over-subscribed, it is likely that schools in less favourable areas will be struggling to attract sufficient numbers of suitable applicants. For example, that data shows a relatively high proportion of physics, chemistry, biology, mathematics and English roles are left vacant compared to other subjects.

Comparisons cannot be drawn with England in this instance, as data on the number of roles advertised, applicants received and teachers appointed is not collected.

Wales and England both face their own challenges

Wales and England both face challenges in meeting the demand for teachers in the next few years. According to future pupil demographics, the number of school aged children is expected to grow by four per cent in Wales and 15 per cent in England by 2025. In each country the teaching population must keep up in order to prevent a teacher shortage.

Although the projected rise in pupil numbers is significantly lower in Wales than England, a tough challenge remains ahead for Wales. Whilst pupil numbers have remained relatively flat in recent years, teacher numbers have been declining for nearly a decade. In 2016, the number of teachers in Wales was six per cent smaller than in 2007. While teacher supply appears to be meeting pupil demand for now, this may not be the case for much longer. With pupil numbers set to rise modestly in coming years, the trend of declining teacher numbers must be reversed.

Between 2011 and 2015, the number of teachers and pupils in England grew at a similar rate. However, with the number of pupils expected to rise rapidly in the next few years, will the number of teachers be able to keep up? In order to meet the demand of a growing pupil population, England must increase the supply of teachers by taking steps to improve teacher retention and recruitment.

The number of teachers in England has kept pace with pupil numbers, but the number of pupils is expected to grow rapidly in the coming years


A school workforce census for Wales?

The Welsh Government recently proposed to replace its existing school workforce collections with an annual individual-level school workforce census, similar to the one that currently takes place each year in England. NFER welcomes this proposal as it will allow greater insight into the teaching workforce in Wales, enable better workforce planning and allow for trends to be carefully monitored over time and cross-country comparisons to be made more accurately.

Could teacher retention be improving?

By Karen Wespieser and Zoe Des Clayes

The latest report by the Education Select Committee about the recruitment and retention of teachers argues that the Government should place greater emphasis on improving teacher retention. The committee explains that, based on the evidence they received, not only is retention  a more cost-effective way to tackle the issue of teacher shortages, but more teachers staying in the profession for longer would strengthen the pool of applicants for leadership positions.

NFER agrees with the Education Select Committee that teacher retention is a priority, and over the past 18 months we have analysed and reported on trends in teacher retention. Our latest evidence suggests that teachers’ intentions are a little more positive than a year ago, particularly in the primary sector, although there continue to be serious challenges for the future.

Over the past five school terms, we have used the NFER Teacher Voice survey to ask a nationally representative sample of over 1,000 teachers whether or not they are considering leaving teaching within the next academic year. We have shared the results of earlier surveys in our Should I stay or should I go? and Engaging teachers reports. The first reports teachers’ intentions to leave teaching at one time point; the second looks at teachers’ intention to leave across four school terms.

This blog considers new data from our fifth and most recent Teacher Voice survey. We compare teachers’ intentions to leave across five time points, allowing us to identify any emerging trends. We’ll follow up and extend this analysis when we have more new data from the next two terms.

November 2016 Teacher Voice findings


The findings from the Autumn 2016 survey tentatively suggest the proportion of teachers intending to leave teaching is falling. Overall, 20 per cent of our Autumn 2016 sample said they were considering leaving teaching within the next year, a significant reduction (5 percentage points) from the 25 per cent of respondents stating their intention to leave the previous autumn.

It is early days, but the latest survey results could be a sign that fewer teachers are now considering leaving the profession. NFER will be monitoring whether or not these figures do indicate the start of a trend that continues throughout the 2016-17 academic year or if this reduction is a one-off.

It will also be important to monitor what proportion of teachers actually leave the profession, since actions can be quite different to stated intentions. However, data on what proportion of teachers in autumn 2016 are retained won’t be available until the 2017 School Workforce Census data is published in Summer 2018.

Analysis by phase

To find out if the reduction in teachers stating their intention to leave between Autumn 2015 and 2016 was in all schools or in certain phases we did some further analysis.


The analysis of our survey data shows that a lower proportion of teachers in both phases, were considering leaving in Autumn 2016 compared with Autumn 2015.

The reduction at primary level was statistically significant, with 22 per cent of teachers surveyed stating their intention to leave in Autumn 2015 compared to 16 per cent in Autumn 2016. However, the proportion of secondary teachers considering leaving is about the same as it was this time last year: 25 per cent in November 2016 compared to 28 per cent in November 2015. The difference between these two time points was not statistically significant.

While the latest results appear encouraging for primary schools, they are concerning for secondary schools which face a faster rise in pupil numbers over the next decade. NFER will be following the trends in both phases in the coming terms.

More data needed

More data is needed to see if this reduction in teachers’ expressed intention to leave is part of a longer-term trend or a one-off. More time points are needed in order to judge whether or not teachers’ intention to leave is affected by the time of year in which the survey is administered.

In March 2017 we should have two whole years’ worth of data and therefore a greater opportunity to explore if there are any seasonal trends. We’ll also have a clearer picture of whether or not the reduction in autumn 2016 continues further into the 2016-17 academic year.

NFER have also recently begun a new piece of research on the teacher workforce, funded by the Nuffield Foundation, which will analyse teacher retention in even greater detail. We will be sharing more about this new project in the next few days.
