Thanks to the DfE reopening the data files on teacher numbers and the calculations behind the need for increased targets it is now possible to ask some more interesting questions about teacher supply.
Two key ones are: what percentage of new entrants should we expect to enter the Further Education Sector and what percentage should we expect to take teaching posts in private schools and tutoring establishments? The DfE should have access to this data from the profiles of ITT providers.
However, there is some sector-wide evidence in the data associated with the Teacher Supply Model in the tables of the percentage completing ITT and percentage employed in state schools that can go some way to addressing these questions.

Completion rates used by the DfE vary from just 84% in the already small cohort of physics trainees to 97% in both Classics and physical education. Percentages entering employment range from 74% of design and technology trainees to 59% of classics trainees and 62% of computing trainees. Physics, with an employment rate of 64%, has a percentage that is little better than computing.
In calculating the number of trainees in the 2022 ITT Census – minus Teach First trainees, as they are already in the classroom – I have assumed the same base level as a starting point as for completion rates as for employment rates. If the percentage entering employment were of the percentage completing, the totals for the latter would be lower.
So, where are the missing 145 physics trainees? Undoubtedly, the largest number are teaching in the private sector; some will be lecturing in Sixth Form of other Further Education colleges and some won’t have entered teaching at all. A few might have decided to work in schools outside of England.
I suspect that the influence of the private sector on these numbers is best seen in the data around classics. The Census recorded 58 trainees, with just 59% entering employment in the state sector. That’s just 34 teachers. With the target for 2023/24 cut to 25, if ITT providers stuck to the target and didn’t over-recruit, it is entirely possible that there would be no Classics trainees available for the state school sector for September 2024.
Now, many may not weep about the loss of classics as a subject, although a cogent case can be made for its retention by those that support it. Fortunately, in history and physical education, where targets have been reduced, low employment percentages may owe more to the over-recruitment against the previous targets than a warning of teacher shortages. However, the contribution of these teachers to the staffing of other subjects may cause other problems for the staff creating timetables for schools in September 2024.
Collateral damage to religious education, where the employment rate of 72% produce a total of only 293 new entrants, is one obvious likely outcome if history numbers are restricted to anywhere close to the 2023 target.
As these numbers haven’t been adjusted for either apprenticeships or the School Direct Salaried scheme, they may well still be slightly too high to represent reality in terms of the ‘open’ labour market.
How they are spread out across the country, is a whole different set of issues that perhaps the Select committee might like to delve into as part of its discussions with the Secretary of State.
