OECD has today published the 2026 edition of ‘Education Indicators At a glance’. Education at a Glance 2026 | OECD The section on teacher shortages has already received several comments on LinkedIn and elsewhere. I though I might look in some detail about the United Kingdom section in the ’country report’ about teacher shortages.

On the face of it, the UK fares well compared with other countries. Apparently, only 2.9% of teachers in state schools are not fully qualified. I wonder what the percentage would be for Further Education?

Teacher shortages

• Shortages of skilled workers have affected many sectors across the OECD in recent years, and the teaching profession is no exception. Teacher shortages manifest in different ways across education systems: in some countries, a lack of fully qualified teachers is reflected in a higher share of non-fully qualified staff, while in others a significant number of teaching positions remain unfilled.
• Non-fully qualified teachers refer to teachers who do not yet meet all the requirements to be recognised as fully qualified teachers under national regulations. In most countries, they either possess the required academic qualifications but lack mandatory certification or teacher training, have completed the required teacher training but do not hold the required academic qualifications, or lack both. In England, 2.9% of all primary and secondary teachers in public institutions were not fully qualified in 2024/25, below the OECD average of 9.1% (Figure 1).
• Countries use two main approaches to measuring teacher shortages. The first approach estimates shortages before or at the start of the school year based on projected recruitment needs. The second approach measures shortages by counting the number of positions that remain vacant at the start of the school year or shortly after it begins. England uses the second approach, and 0.6% of all teaching positions in public secondary education were unfilled at or shortly before the start of the 2024/25 school year (Table 2).

However, it is important to delve into what’ ‘Qualified’ actually means.

In England, possession of QTS allows teachers, not, interestingly, a reserved occupation term, to teach anything to anyone at any level. For the past 25 years, I have been asking for QTS to be linked to phase and subject studied in ITT. However, apart from in the Liberal Democrat Manifesto in 20025, there has been no political appetite to limit QTS in any way. I still think that is a mistake. The over-supply of PE and history teachers has helped keep school fully staffed during the recruitment crisis that started way back in 2013, but may now be coming to an end.

It is also worth pointing out that schools can be fully staffed in England by adjusting the curriculum, and dropping subjects they cannot staff. The other alternative, as OECD noted, is using less well-qualified staff. The figures on combined versus separate science at Key Stage 4 between different types of school are stark. The former can be staffed with teachers with less subject knowledge than the latter. If you don’t pass the 11+, you probably won’t study Physics as a subject by KS4 | John Howson

I was surprised that OECD appears to have accepted the DfE data at face value and not to have a definition that would deal with the fact that QTS is so broad as to be meaningless at both primary and secondary school levels.
