Why Schools Are Losing Staff – And What Leaders Can Do About It
Across the UK education sector, a growing challenge is placing increasing pressure on school leaders: teacher recruitment and retention.
While teaching remains one of the most impactful professions, the reality for many schools in 2026 and beyond is clear – teachers are leaving the profession faster than they are being replaced, and the cost of covering vacancies continues to rise.
For Multi-Academy Trusts, local authorities and school leaders managing tight budgets, finding a sustainable way to maintain teaching quality while controlling costs has never been more critical.
A Workforce Under Pressure
Recent national data paints a worrying picture of the current teacher workforce.
- Around 9-10% of teachers leave the profession each year in England.
- More than 41,000 teachers left state schools in 2023–24 alone.
- Between 10% and 15% of newly qualified teachers leave within their first year in the state sector.
- And more than one in three teachers leave within five years of entering the profession.
At the same time, recruitment has struggled to keep pace with demand. Vacancy rates are significantly higher than before the pandemic, while pupil numbers continue to rise in many areas.
The result is a growing workforce gap that schools must fill quickly to maintain continuity for pupils.
Budget Challenges Are Intensifying
Alongside staffing pressures, school finances remain under strain.
Rising costs, increasing support needs for pupils, and tight public funding settlements mean that many schools are being asked to deliver more with less.
These financial pressures create a difficult balancing act:
- Maintaining high-quality teaching
- Supporting staff wellbeing and retention
- Managing agency costs
- Ensuring budget sustainability
For many trusts and school leaders, supply staffing is no longer just about short-term cover – it is now a critical workforce strategy.
Rethinking Supply: Ethical Partnerships Matter
The traditional supply model has often been criticised for its cost structures and lack of transparency.
Reports suggest schools collectively spend over £1 billion per year on supply teachers, with the majority going through private agencies.
For schools facing financial pressure, working with the right partner can make a significant difference.
An ethical supply partner structured as a financial mutual operates differently.
Instead of prioritising shareholder profit, the model focuses on:
- Reinvesting into schools and education
- Fair pay for supply teachers
- Transparent pricing
- Sustainable workforce planning
This approach helps schools achieve both cost savings and improved quality of staffing.
Removing Barriers to Permanent Recruitment
One of the biggest frustrations for school leaders using supply staff is the cost of converting great teachers into permanent employees.
Many agencies charge large “finder’s fees” when schools want to employ someone permanently.
Ethical supply models remove that barrier.
Key benefits can include:
- No fixed fees when a school appoints a supply teacher permanently
- Freedom to recruit great staff without penalty
- Greater flexibility in workforce planning
For schools trying to stabilise their staffing model, this makes a major difference.
Building a Stronger Supply Bank
A further challenge many schools face is access to reliable supply teachers who understand their setting.
One solution is building a dedicated supply bank of trusted professionals who already know the school or trust.
Supply partners can support this by offering:
- Term-time contracts for supply teachers
- Stable employment conditions for educators
- Consistent availability for schools
- Stronger relationships with staff and pupils
This approach supports both teacher wellbeing and continuity for learners.
A Regional Approach to Supporting Schools
Across England, different regions are experiencing teacher shortages in different ways.
Targeted regional partnerships can help schools access local talent pools and responsive staffing support.
Schools and trusts across the following regions are increasingly exploring alternative supply models:
- North East
- East Midlands
- West Midlands
- South East
Working with an ethical, education-focused partner can help ensure schools maintain quality teaching while managing budgets responsibly.
The Future of School Staffing
The teacher retention challenge is unlikely to disappear overnight.
But schools that take a strategic approach to workforce planning, including ethical supply partnerships and flexible staffing models, will be better positioned to:
- Maintain teaching quality
- Support staff wellbeing
- Protect school budgets
- Build sustainable recruitment pipelines
Education deserves solutions designed for the sector – not simply profit-driven agency models.
