The OECD’s Education at a Glance 2026, published on September 29, gives teacher shortages a dedicated focus. The report treats staffing pressure as a question wider than how many jobs remain advertised: qualification pathways, retention, and the distribution of teachers also matter.
One headline finding is that 9.1% of primary and secondary teachers across OECD countries were classified as not fully qualified in the report’s latest comparison. That figure needs its definition and scope alongside it. It is not a count of empty classrooms or a finding about every individual school.
What does the qualification indicator measure?
The report explains that teachers in this category do not yet meet all the relevant national requirements. These may concern academic qualifications, certification, or teacher training. Some are teaching while completing a pathway to full qualification.
National requirements differ, so the same label does not describe an identical professional background everywhere. The chapter’s main reference period is the 2024/25 academic year, with country exceptions noted in its tables. Much of the staffing collection concerns public institutions; readers should check each indicator’s coverage.
Those distinctions change the questions worth asking. If a teacher is completing certification, a useful discussion concerns supervision, preparation, and the route to qualification. If a post has no suitable applicant, recruitment may be the more immediate issue. Combining both situations into one dramatic label makes it harder to identify a response.
A vacancy total cannot describe every classroom
The OECD highlights variation between places and subjects. Its overview identifies mathematics and natural sciences as areas of particular difficulty and notes that pressures can be greater in remote or disadvantaged locations.
The implication is that a national summary should begin a discussion, rather than finish it. An apparently manageable overall vacancy rate could coexist with a difficult situation in one subject or area. Equally, a concerning national figure does not establish that every school experiences the same shortage.
For a reader trying to understand a local announcement, the next step is to find out what has actually changed there. Is the school advertising a permanent vacancy, seeking temporary cover, or supporting a teacher through qualification? Those are different descriptions of a staffing need.
They also imply different evidence. A current vacancy notice may identify a recruitment problem, but it does not by itself reveal how often lessons have been interrupted. A qualification statistic describes workforce composition, but cannot substitute for a report on the support available to an individual teacher.
Read the date and denominator together
A report released in 2026 can draw on an earlier academic year. Treat the publication date as the date the comparison became available, not automatically as the date every measurement was taken.
Before repeating a percentage, identify who is counted and what the total represents. A share of teaching positions, a share of employed teachers, and a share of students attending certain schools answer different questions. They should not be exchanged in a headline merely because each is expressed as a percentage.
The report’s Readers Guide and table notes provide the context for these comparisons. Missing data, country coverage, and definitions deserve attention before arranging results into a simple league table. A blank entry should not become an assumed zero.
A useful habit is to write the claim in full before shortening it: which group, which period, which measure, and which exceptions? If those details cannot survive the shortened version, the headline needs revising.
What would a useful local follow-up ask?
The international report offers a starting point for local reporting. It does not supply the answers to these practical questions:
- Which subjects or year groups currently need staff?
- How are classes being covered while recruitment continues?
- What preparation and support are provided to teachers completing qualification?
- How is the authority measuring whether its staffing plan improves continuity?
Ask for information in aggregate rather than seeking personal details about a particular employee. Parents need to understand the arrangements for teaching, while staff deserve a discussion grounded in their role and support rather than assumptions about a statistical label.
The value of the 2026 edition is the wider view it brings to the staffing debate. Using that view well means separating an empty position from a qualification pathway, a national average from a local experience, and a published indicator from a conclusion it cannot support.
