From Staffing Pressure to Workforce Strategy: A Better Way Forward for Schools
Recruitment remains one of the most persistent challenges facing education leaders. Although the latest national data shows that teacher vacancies and temporarily filled posts have fallen from their 2023 peak, the wider picture remains demanding. The number of full-time equivalent teachers in state-funded schools fell by around 1,900 between 2024 and 2025, while the number of qualified teachers entering the workforce also decreased.
At the same time, schools are managing absence, specialist subject shortages, rising demand for SEND support and continued pressure on budgets. In November 2025, schools reported 20,500 occasional teachers working on census day, compared with 17,700 the previous year. Supply staffing is therefore not simply an emergency measure. It is an important part of how schools maintain continuity and protect learning.
The question is not whether schools will need flexible staffing. It is whether that need will be managed reactively or strategically.
The hidden cost of reactive recruitment
When every absence or vacancy is treated as a separate emergency, the consequences can extend well beyond the daily charge rate. Leaders and school business teams spend valuable time contacting multiple agencies, checking compliance, comparing unfamiliar candidates and resolving different booking, timesheet and invoicing processes.
Reactive decisions can also make it harder to achieve consistency for pupils. A succession of unfamiliar staff may disrupt routines, place additional pressure on permanent colleagues and reduce confidence across the school community.
A strategic approach starts earlier. It looks at workforce demand across the school, trust or region; identifies recurring gaps; builds reliable candidate pipelines; and uses management information to guide future decisions.
What does strategic workforce planning look like?
For schools and trusts, it can include:
- reviewing patterns in absence, vacancies and agency use;
- identifying hard-to-fill roles and likely pressure points in advance;
- creating a dependable bank of quality-assured teachers and support staff;
- coordinating demand across several schools to improve continuity and value;
- monitoring candidate performance, fulfilment and expenditure; and
- developing routes from temporary placements into longer-term appointments where appropriate.
This turns supply staffing from a series of transactions into a planned workforce resource.
How Schools Mutual Services can help
Schools Mutual Services is a not-for-profit organisation, owned by schools and created for education. Our priority is not generating returns for shareholders. It is helping schools secure dependable people, maintain quality and achieve better value.
We work with leaders to understand the wider workforce picture, not simply the vacancy in front of us. By building dedicated local candidate pools and developing knowledge of individual schools, we can support planned cover, short-term absence, long-term placements and permanent recruitment as part of one joined-up approach.
SMS is also an approved supplier on the Government Commercial Agency Supply Teachers and Education Recruitment Framework, RM6376. The framework provides a compliant route to temporary, fixed-term and permanent education staffing, with accredited suppliers, transparent charges, safeguarding standards and capped supplier fees.
Our agreed SMS rates can be up to 50% lower than the published framework rates, depending on the role and assignment. That gives schools and trusts the opportunity to reduce costs while continuing to focus on candidate quality, safeguarding and service.
Stronger decisions start with better information
An effective workforce strategy should give leaders a clear view of what they are spending, where demand is arising and whether current arrangements are delivering value. It should also protect candidate pay and avoid a race to the bottom on quality.
That is why SMS places transparency at the centre of the relationship. We help schools understand the complete cost of supply, plan against future needs and challenge arrangements that may have developed without strategic oversight.
The education workforce will continue to change. Schools cannot control every absence, vacancy or national recruitment trend, but they can control how they prepare and respond.
