How Do You Teach in PRU Settings as a Supply Teacher?
Teaching in a Pupil Referral Unit (PRU) as a supply teacher can be one of the most challenging and rewarding experiences in education. PRUs support children and young people who have been permanently excluded, are at risk of exclusion, or cannot attend mainstream school for medical, SEMH or behavioural reasons. As a result, PRU classrooms require calm, confident adults who can build trust quickly, uphold high safeguarding standards and deliver learning in a flexible, emotionally intelligent way.
At First Class Supply, we work closely with PRUs and alternative provision settings across the North East. Our insight is shaped by the lived experience of supply teachers, support staff and school leaders who understand the realities of SEMH support. If you’re exploring opportunities in alternative provision, you can find guidance in why choose First Class Supply and browse further information through our resources for teachers.
Below is a practical guide designed to help you enter PRU settings confidently while protecting your wellbeing and maintaining strong professional practice.
What Makes PRU Supply Teaching Different?
PRUs are fast-paced, highly personalised environments. Classes are small, often between 2 and 8 pupils, with strong pastoral support. Students may have:
- SEMH needs
• Trauma backgrounds
• Behaviour linked to unmet needs
• Anxiety or school-avoidance
• SEND such as ADHD or ASD
• Low academic confidence
Because of this, PRUs expect supply teachers to be emotionally intelligent, predictable, consistent and professional — not perfect, but dependable.
If you’re preparing for supply work more generally, our article on 8 important skills you need as a supply teacher gives a helpful foundation.
1. Start With Strong Safeguarding and Risk Awareness
Safeguarding in PRUs is robust and non-negotiable. You must be prepared before you arrive.
Safeguarding Expectations in PRUs
- Know the Designated Safeguarding Lead (DSL)
• Understand local safeguarding procedures
• Record concerns instantly and factually
• Maintain strict professional boundaries
• Never be alone in a room with a pupil if local policy requires two-staff presence
• Understand the physical intervention policy (you will not be expected to use restrictive practices as a supply teacher)
• Be aware of risks around absconding, self-harm or emotional escalation
If you’re joining an agency for the first time, our guide on how to register as a supply teacher in the North East covers safeguarding checks and DBS expectations.
PRUs often provide a safety briefing on arrival. Take it seriously. It will include key information such as safe spaces, trigger warnings and emergency procedures.
2. Build Relationships Before You Teach
In PRUs, connection comes before curriculum. Pupils will often test supply teachers to check whether you are:
- Respectful
• Calm
• Consistent
• Boundaried
• Genuine
A simple introduction goes a long way:
Example script:
“Good morning, I’m Ms/Mr ___. I’m here to help you learn today. We’ll keep things calm, safe and simple, and I’ll let you know what’s happening before each activity.”
Be friendly without being overfamiliar. PRU pupils respond best to adults who are predictable and emotionally steady.
If you need support with professional communication skills, you might find our guide on creating a standout CV for supply teaching surprisingly helpful — many of the principles apply to day-to-day interaction.
3. Keep Your Teaching Simple, Structured and Adaptable
PRU classes often contain mixed ages, mixed abilities and highly varied emotional states. Lessons need to be short, purposeful and positive.
A Simple PRU-Friendly Lesson Outline
- Clear opener: “Here’s what we’re doing today.”
• Short tasks: 5–10 minute chunks.
• Choice: Offer alternative ways to complete a task.
• Movement: Allow short breaks when needed.
• Success: Celebrate any progress.
• Reflection: End with a quick “What went well today?”
If the school has not provided a plan, our article on what to do if no lesson plan is left will help you stay calm and professional.

4. Behaviour Management in PRUs: Calm, Consistent, Non-Confrontational
Behaviour in PRU settings is often linked to unmet needs, trauma or emotional dysregulation. Traditional mainstream strategies may not work.
Effective Behaviour Strategies
- Stay calm at all times
• Use low-arousal communication (“Let’s take a moment…”)
• Give clear, short instructions
• Avoid raised voices
• Offer choices rather than ultimatums
• Don’t take behaviour personally
• Praise micro-successes
• Move away from power struggles
• Allow time and space when pupils escalate
• Use restorative conversations after conflict
Our blog on supply teaching myths includes useful reassurance on behaviour expectations.
5. Work With Support Staff — Never Against Them
TAs and support workers in PRUs are experienced specialists in SEMH support. They understand triggers, de-escalation methods and individual plans better than anyone.
How to Build a Strong Partnership
- Ask for guidance
• Listen to their advice
• Keep them informed
• Share concerns calmly
• Ask how best to support each pupil
• Treat their expertise with respect
Many supply teachers credit their success in PRUs to TAs. You can see similar feedback in our testimonials.
6. Prioritise Safety, Boundaries and De-Escalation
PRU settings expect supply teachers to be vigilant and proactive.
Safety Tips for PRU Classrooms
- Remove unnecessary items from tables
• Sit or stand in accessible positions (not blocking exits)
• Keep your belongings secured
• Know where safe spaces and exits are
• Follow school protocols in escalations
• Never attempt to physically restrain a pupil unless trained and authorised
• Step back if needed — you’re never expected to handle a crisis alone
If you need a refresher on wider school expectations, explore our information for schools for insight into how settings rely on high-quality, safety-first supply staff.
7. Plan for Emotional Needs Before Academic Needs
PRU pupils may walk in dysregulated or anxious, so emotional safety must come first.
Helpful Emotional-Support Strategies
- Greet pupils by name
• Check in casually (“How’s your morning going?”)
• Keep transitions slow and predictable
• Avoid sarcasm
• Use humour carefully and gently
• Give reassurance without lowering expectations
• Provide quiet workstations when needed
Short success-based tasks also build confidence, especially for pupils who have repeatedly experienced school as a difficult environment.
8. Communicate Clearly With Staff, Parents and Carers
You may not meet parents directly but communication through staff is essential — especially when behaviour incidents occur.
What Schools Expect From You
- Clear handover notes
• Factual behaviour descriptions
• No blame language
• Notes on strategies that worked
• Safeguarding information passed to the DSL immediately
• Respectful, calm communication with all staff
If you’re exploring a long-term future in education, see our guide on transitioning to full-time roles.
9. Look After Your Own Wellbeing
PRUs can be emotionally demanding. Good supply teachers maintain professional boundaries and prioritise their own wellbeing.
Wellbeing Strategies
- Take your breaks away from the classroom
• Debrief with staff — not alone
• Don’t carry incidents home emotionally
• Celebrate small wins
• Remember: difficult behaviour is not about you
• Ask for support — you are part of a team
Our community section includes stories from educators who found resilience through support networks.
10. End the Day With a Professional, Helpful Handover
A clear handover note helps the next teacher maintain consistency — vital in PRU settings.
Include in Your Handover
- Tasks completed
• Behaviour notes
• De-escalation strategies that worked
• Any safeguarding concerns shared with the DSL
• Suggestions for next steps
Schools appreciate supply teachers who communicate well and leave the room ready for the next session.
Career Progression and Opportunities in PRU and SEMH Settings
PRU experience is highly valued. Many supply teachers later transition into:
- SEMH specialist roles
• Behaviour mentor positions
• Pastoral support roles
• Alternative provision teaching
• Long-term PRU placements
