France Teacher Shortage 2026: What the 18% Unfilled-Post Number Really Means for Schools

An “18% unfilled” teacher-recruitment number is circulating this week — and for schools with an open computer-science or German post, it’s real. For nearly everyone else, it’s being misquoted.

That figure traces back to July 9, 2026, when France’s Ministry of Education published the final results of this year’s teacher recruitment exams — numbers reproduced by the national teachers’ union SNES-FSU, which confirm what headteachers have suspected for months: some subjects are going into the September rentrée without enough new recruits to fill the posts on offer SNES-FSU.

The headline number is real. But it needs precise scoping, because the way it’s being repeated in some places overstates its reach. For school administrators trying to plan for September, the difference matters — and so does what sits underneath the headline: a recruitment calendar that leaves almost no lead time, and a classroom-level staffing gap that predates this year’s exam results entirely.

What the July 9 numbers actually say

Across all 2026 teacher recruitment exams combined, 683 of 13,576 offered posts went unfilled — an overall shortfall of 5.03% SNES-FSU. That is the honest, undifferentiated aggregate, and it is worth stating clearly before anything else: most posts across most exam routes were filled.

The 18% figure sits one level down, inside a specific recruitment track: the “3e concours,” France’s career-changer exam pathway for candidates entering teaching from another profession. Within that track, 18% of posts overall went unfilled — and the shortfall is far from evenly spread across subjects. Within the third-competition route, computer science (NSI) reached 67% unfilled, German 42%, and mathematics 30% SNES-FSU.

The main external exam tracks (external CAPES and external agrégation, which most new teachers still enter through) show their own, separate per-subject shortfall rates — generally lower than the third-competition figures, but not negligible: external CAPES mathematics lost 17% of its posts, external agrégation mathematics lost 23%, and external agrégation SII (industrial sciences, the source’s own label for this post) lost 29% SNES-FSU. Mathematics carries particular weight here because it is also the subject with the largest single recruitment target: 1,430 CAPES posts were offered nationally this session, more than any other discipline, against a national CRPE (primary-school) allocation of roughly 11,000-plus posts overall Ministère de l’Éducation nationale.

So: the 18% figure is real, it is scoped to the career-changer track, and it is not the whole story on its own — but a school with even one computer science or German post filled through that route now has a meaningfully higher-than-average chance of starting the year with an empty seat at the front of that classroom.

A recruitment calendar with almost no slack

The reason this news is landing on administrators’ desks now, rather than months ago, is timing. Final admission results across the different exam tracks were only confirmed in a narrow window between late May and early July 2026 — CRPE results ran June 5–30, agrégation June 2–July 3, and CAPES June 4–July 6 Ministère de l’Éducation nationale. In other words, the unfilled-post rate for this rentrée was locked in only about seven weeks before students return to class in September. That leaves academies, and the schools underneath them, very little runway to reallocate, recruit substitutes, or otherwise plan around confirmed gaps before the school year starts.

The staffing gap schools were already carrying

Here is the part that matters most for day-to-day planning: this exam-shortfall story is landing on top of a system that was already short-staffed before July 9 arrived. A survey of headteachers presented by the SNPDEN-UNSA union in late May 2026, reported by Café pédagogique, found that 41% of schools already had at least one unreplaced absent teacher, and 58% were missing between two and five educators Café pédagogique. Three-quarters of principals surveyed — 76% — said they personally compensate for the gap by reorganizing schedules, taking on administrative tasks, or redistributing duties among already-stretched teams.

That survey is independent of the exam results discussed above; it measures a classroom-level reality, not a recruitment-pipeline statistic. But the two data points are consistent with each other: a system where more than half of schools are already juggling multiple unfilled roles is not well positioned to absorb a further recruitment shortfall in specific subjects, however precisely that shortfall is scoped.

The exam shortfall is not the only factor

Even if every recruitment post had been filled, two other pressures would still be squeezing French classrooms this year: budget and attrition. First, budget: unions have flagged 4,000 planned job cuts in the education sector for the 2026–2027 year, with the Poitiers academy (covering Charente, Charente-Maritime, Deux-Sèvres, and Vienne) and the Aix-Marseille academy named as specifically affected — a policy and funding decision, distinct from the recruitment-exam numbers themselves The Connexion. Second, attrition: a government strategy-commission report analyzed in September 2025 — describing 2024 rentrée conditions, so a year ahead of the figures above — found that 3,200 teachers were already missing at the start of that school year, and argued the deeper issue is working conditions and career sustainability rather than a lack of vocational commitment, noting that 92% of teachers surveyed did not regret choosing the profession Pedro De Bruyckere / Haut-Commissariat. Consistent with that, UNESCO data cited by Euronews in September 2025 attributes over 90% of Europe’s estimated teacher shortage to educators leaving the profession, not to recruitment failure alone — framing France’s 2026 exam story as one chapter in a broader continental retention challenge Euronews.

What this means for administrators heading into September

None of the above changes the operational reality: some schools will open the 2026 rentrée with confirmed gaps in specific subjects, discovered late, on top of vacancies that were already being patched together in May. Whatever combination of recruitment shortfall, budget decisions, and attrition is behind any individual school’s staffing picture, the practical requirement is the same — administrators need a fast, reliable way to tell staff, parents, and students about coverage changes and schedule adjustments as they happen, not weeks later.

In practice, this looks like three things:

A same-day staffing-change notice. When a subject teacher’s post can’t be filled or a substitute falls through, a short push notification (2–3 sentences) goes to the affected class’s parent group within hours of the school confirming the gap — not appended to a weekly newsletter. Sample content: “Update: Mme. Dubois’s mathematics class will be covered by a substitute teacher starting Monday, September 7, while recruitment continues. Homework schedule is unaffected.”
A rolling coverage-status page for staff. Rather than an email chain, a pinned, continuously updated post in a staff-only channel tracks which classes are affected, who’s covering, and expected duration — updated within the same day whenever the picture changes, so teachers aren’t reorganizing schedules on guesswork. In practice: a pinned post reads “Coverage tracker — updated July 14: 5e Maths (Mme. Dubois) — substitute confirmed, starts Sept 7. 4e German — no substitute yet, admin covering study hall Tues/Thu.” Staff refresh one place instead of asking in the lounge.
A start-of-year parent briefing. A single, slightly longer message (one screen’s worth of text) sent in the week before the rentrée, acknowledging any known subject gaps directly and explaining the interim coverage plan — set expectations once, clearly, instead of fielding the same question individually from dozens of parents. In practice: “Ahead of the September 7 rentrée, we want to be upfront: our German post is not yet filled. Here is our interim plan while recruitment continues…”

The question is when, not if

The precise scoping matters — 5.03% overall, 18% within the third-competition track, up to 67% in computer science within that same track — but the operational conclusion doesn’t hinge on which number a school falls under. A recruitment calendar that confirms staffing gaps seven weeks before the rentrée, layered onto a system where more than half of schools were already covering unfilled posts in May, means fast and specific communication about coverage changes stops being a nice-to-have and becomes part of how a school runs in September. Schools that want to weather this well would likely need to focus less on how many gaps they have and more on how quickly and clearly they tell people about them — before rumor and uncertainty fill the space instead.

Every school will eventually need a reliable channel for exactly this kind of time-sensitive update — the only open question is whether that channel gets built before the next staffing surprise, or after it. BeeNet’s messaging and announcement features offer one implementation path for getting same-day updates to the right group without a phone tree, alongside role-based channels for staff-only coordination. If your school is weighing how to handle this rentrée’s coverage gaps, our use cases for schools walk through how that looks in practice.
