Seventy per cent of the teacher pledge – but what happened to deployable capacity?
The pledge and the school workforce census measure different things. Boards need a clearer account of the qualified teaching time actually available to pupils.
The answer in brief
The pledge can advance while deployable capacity falls elsewhere.
The government says 4,654 additional teachers have been counted towards its 6,500 pledge: 3,008 in secondary and special schools and 1,646 in further education. It describes this as 70% delivery. That policy count covers selected settings and a different reporting period from the annual school workforce census.1
The November 2025 census recorded 466,372 teacher full-time equivalents across state-funded schools, around 1,900 fewer than a year earlier. Both statements can be true because they answer different questions about scope, timing and measurement. Neither alone shows how much qualified teaching time reached a particular pupil, subject or locality.2
- The 4,654 pledge figure and total state-school teacher FTE are not like-for-like measures.
- Entrants exceeded leavers, but reductions in existing teachers' hours removed substantial aggregate capacity.
- Boards need evidence about delivered, subject-appropriate teaching time – not headcount alone.
01 / Two different measures
Start by separating the policy count from the whole-school workforce.
The pledge measure covers secondary and special schools and further education colleges. The school workforce census covers state-funded schools, excludes further education and reports full-time equivalents. Treating the 4,654 policy count as a change in whole-school FTE would collapse distinct populations, periods and methodologies.12
The useful question is not which number defeats the other. It is whether the people counted in priority settings translate into sufficient teaching capacity by phase, subject and place. That requires recruitment reporting to be reconciled with contracted hours and deployment while preserving each source's boundary.12
02 / The capacity ledger
Entrants and leavers are only part of the capacity equation.
There were 41,012 entrant FTE and 38,632 leaver FTE in the latest census year, a positive difference of about 2,400. Yet 6.2% of teachers reduced their working hours while 4.2% increased them. Taken together, changes in hours produced an estimated net reduction of about 2,950 FTE.2
The release does not show whether pay, workload, health, caring responsibilities or personal preference caused those changes. It does show why entrants minus leavers is an incomplete measure. A teacher moving from full-time to 0.6 remains in headcount while supplying materially fewer timetable hours.2
03 / Phase and subject
National totals conceal where capacity has moved and what it can teach.
Primary and nursery teacher FTE fell by around 2,900 and secondary teacher FTE by roughly 500, while special and pupil referral unit teacher FTE rose by about 1,100. Falling pupil numbers are relevant, particularly in primary, so an FTE reduction should not automatically be described as a shortage.23
Deployment also matters. DfE reports that 86.8% of secondary teaching hours were delivered by a teacher with a relevant post-A-level qualification, with variation between subjects. That qualification measure is an imperfect specialism proxy, but it is closer to pupils' classroom experience than an undifferentiated national count.2
04 / Pressure signals
A lower vacancy snapshot does not settle the continuity question.
The census recorded about 1,600 advertised vacancies or temporarily filled posts, down from around 2,200 a year earlier. It also recorded 20,500 occasional teachers present on census day, up from 17,700. Both measures are snapshots and neither captures all uncovered lessons, agency usage or repeated short-term cover.2
Five-year retention for the relevant entrant cohort was 67.4%, while 91% of recorded leavers left state-funded teaching rather than retiring. These indicators justify continued attention, but they do not identify an individual's reason for leaving or establish that one policy caused the pattern.2
05 / The board account
Boards need a termly account of usable teaching time.
A board receiving only establishment headcount, vacancy totals and payroll variance may miss reduced hours, repeated short-term cover or subject gaps. A stronger account would reconcile contracted FTE, timetabled hours, absence, unfilled lessons and relevant-qualified delivery against pupil numbers.2
Government has announced an autumn 2026 retention programme covering peer support, coaching, workload, wellbeing and flexible working. Leaders should monitor whether flexible arrangements retain expertise as well as how they alter available hours. Flexibility should never be treated as evidence of lower commitment.1
Leadership questions
Questions that turn the development into a governing conversation.
Board test
How have contracted and delivered teacher hours changed per 100 pupils?
Board test
Which subjects rely most on non-specialist, temporary or repeated cover?
Board test
How much capacity was lost or retained through changes in working hours?
Board test
Are recruitment claims reconciled with payroll, timetable, absence and leaver data?
School Connection intelligence lens
What the national Observatory can add, and where it must stop.
Observatory test: create a termly school-level panel from November 2024 to July 2027. Report teacher headcount; contracted FTE per 100 pupils; scheduled and delivered teaching hours per 100 timetable hours; absence-covered and unfilled hours; relevant-qualification share by subject; entrants, movers and leavers; hours increased or reduced; vacancies; and temporary-staff days. Segment by phase, subject, region, trust status, deprivation and SEND.123
Publish absolute and per-pupil change separately. Test associations over time, but do not assign causation to pay, workload, policy or governance without an appropriate counterfactual. Preserve the pledge count and whole-workforce FTE as separate series.12
Only human-approved, public-safe intelligence can appear here. Private candidates, commercial signals, contacts, opportunity values and internal scores are never exposed through School Connection.
Evidence boundary
What this analysis does not prove.
- Public-safe boundary: publish aggregated school groups and suppress small cells rather than exposing individual working patterns.
- Public-safe boundary: do not equate part-time or flexible working with weak commitment.
- Comparison boundary: never subtract the pledge count directly from the whole-workforce FTE change.
- Evidence limitation: the annual workforce census is a November snapshot and misses within-year volatility.
- Evidence limitation: pledge and workforce figures differ in scope, period and methodology.
- Evidence limitation: qualifications, vacancies and occasional-teacher counts are incomplete proxies for teaching quality and continuity.
What we are monitoring next
Publication is the beginning of the watch.
- DfE's autumn 2026 teacher-retention programme, participation measures and evaluation design.
- The December 2026 initial teacher training census, particularly subject and salaried-route recruitment.
- The November 2026 workforce census and any subsequent revisions to hours, retention and deployment measures.
Approved public intelligence
What the live evidence is showing now.
School Connection continues to monitor workforce, leadership & capacity evidence. New machine-detected signals remain private editorial candidates until a human editor investigates and approves them for publication.
This panel reads only the editor-approved School Connection public feed. It never exposes raw Observatory records, private candidates, contacts, commercial opportunities or internal scores.
