Without unique job reference numbers, keeping track of changes in the labour market for teachers requires some careful detective work. While most vacancies are probably filled from the first advertisement, some are not, causing the post to be re-advertised. Some posts are also advertised in several different locations, usually without a school considering whether such a practice is cost effective.
There are also some schools that advertise ‘talent banking’ vacancies where there is probably not a job behind the advertisement, but the school can access details of potential applicants when a vacancy does arise. This is a common practice in the recruitment world, and can mislead those seeking to understand how many teaching vacancies there really are in a year.
TeachVac www.teachvac.co.uk now has the data from the first seven months of 2021 for the teacher labour market in England. Overall, vacancies recorded are up from 42,700 to 45,400 for the first seven months of this year compared with the same period in 2020. However, there are marked differences between the sectors. Primary vacancies are up by 40% from 10,000 to 14,000 whereas secondary headline vacancy numbers are down by some 7%.
But, are secondary vacancies really down, or is it just that more vacancies are being filled at first advertisement? Business Studies, one of the subjects largely ignored by governments that normally struggles to find sufficient applicants registered a 2% increase in 2021, against the overall downward trend. Most subjects with increases this year are minority subjects such as economic; health and Social Care; Law; psychology and sociology. However Design and Technology has experienced a similar 2% increase to that of business studies and biology has recorded a 3% increase. Interestingly, physical education has also seen a 2% increase.
More spectacular are the 18% decrease in vacancies in mathematics and the 15% in general science posts. (Specific physics vacancies fell by 7%). English vacancies were down by 11%.
In order to gauge how much of the deduction might be down to less need to re-advertise, vacancies for teachers of mathematics posted by school in the London Region were reviewed for the January to July period in each year between 2018 and 2021
| Total schools | Schools 2+ vacancies | Schools 4+ vacancies | |
| 2021 | 185 | 51% | 10% |
| 2020 | 181 | 52% | 15% |
| 2019 | 184 | 61% | 23% |
| 2018 | 155 | 57% | 17% |
There are certainly fewer schools with more than one vacancy both this year and in 2020. The reduction in the percentage of schools with 4+ vacancies is even more marked. This might suggest that in the London Region there might be some credence to the theory that schools have found posts easier to fill since the pandemic struck. This despite the fact that the total number of schools posting at least one vacancy for a teacher of mathematics has remained consistent over the past three years at between 181 and 185 schools in both the state and independent sectors recorded as placing a vacancy for a teacher of mathematics.
Within London there are regional differences with South East London schools seemingly finding recruitment more of a challenge than schools north of the River Thames.
