Stepping into a new classroom as a supply teacher can be daunting. You’re faced with unfamiliar faces, routines, and expectations. Yet, with the right approach, you can quickly establish a positive, productive environment—no matter how short your stay.

1. Make a Strong First Impression
Your first moments in the classroom set the tone for the entire lesson. Walk in confidently, introduce yourself, and write your name clearly on the board. Take time to learn students’ names and use them when addressing the class. This simple gesture helps build rapport and signals your authority.
2. Set Clear Expectations
Right from the start, outline your rules and expectations for behaviour. Explain the consequences for misbehaviour and any routines you expect students to follow. Consistency is key—reinforce these expectations throughout the lesson and apply consequences fairly. Establishing authority early makes it easier to manage the class effectively.
3. Know the School’s Behaviour Policies
Before teaching, familiarise yourself with the school’s behaviour management policy and reward system. Locate the behaviour management handbook and identify key staff members, such as the Head of Year or SEN coordinator, who can support you if needed. Follow school protocols for dealing with disruptive behaviour and reporting incidents. If you’re unsure about any procedures, ask a colleague or member of staff for guidance.
4. Prevent Problems Before They Start
Prevention is better than cure. Keep students engaged with well-paced lessons and clear instructions. Use positive reinforcement—verbal praise or rewards—to encourage good behaviour. Non-verbal cues, like eye contact or moving closer to a disruptive student, can help manage minor issues without interrupting the flow of the lesson. Position yourself so you can see all students and move around the room easily.
5. Respond Calmly to Challenging Behaviour
Despite your best efforts, you may encounter challenging behaviour. Address issues promptly and consistently, using the school’s sanctions system. Give clear warnings before escalating consequences and avoid confrontations. Stay calm and professional, even in difficult situations. Document serious incidents thoroughly, noting times, students involved, and actions taken—this helps maintain transparency and supports the school’s behaviour management system.
6. Build Positive Relationships
Even if you’re only in the classroom for a short time, building positive relationships with students can make a big difference. Show genuine interest in their learning and ask teaching assistants about class dynamics. Use praise to acknowledge good behaviour and academic achievements, creating a positive atmosphere that encourages students to stay engaged.
Conclusion:Managing classroom behaviour as a supply teacher requires a blend of confidence, consistency, and empathy. By setting clear expectations, following school protocols, using preventative strategies, handling challenges calmly, and building positive relationships, you can create a productive learning environment—even in unfamiliar settings.
