What Schools Look for in a Great Supply Teacher
Discover what UK schools look for in a great supply teacher. Learn the skills, qualities, and tips to succeed in supply teaching with Dunbar Education.
Supply teachers play a vital role in UK schools. Whether covering short-term absences, maternity leave, or stepping into a long-term role, supply teachers keep classrooms running smoothly and ensure pupils don’t miss out on learning.
At Dunbar Education, we work closely with headteachers and supply staff every day. Here’s what schools consistently tell us they value most in a great supply teacher.
01 Reliability and Punctuality
The first thing schools ask for is someone they can rely on. Being on time, prepared, and ready to step in makes all the difference. Schools need to know that when they book a supply teacher, they won’t be left short-staffed.
02 Strong Classroom Management
Supply teachers often walk into unfamiliar classrooms. Schools want to see calm authority, clear expectations, and a positive approach to behaviour management.
Tip: Mention behaviour strategies on your CV and at interview — it’s one of the first things headteachers look for.
03 Flexibility and Adaptability
No two supply days are the same. You may be covering Year 4 in the morning and Year 9 Science in the afternoon. The best supply teachers stay calm, adapt quickly, and get stuck in, even when plans change last-minute.
04 Positive Relationships with Pupils
Schools notice when a supply teacher builds rapport quickly. A smile, encouragement, and genuine interest in pupils’ learning go a long way. Pupils respect supply teachers who are approachable but firm.
05 Professionalism
Great supply teachers:
● Dress appropriately for the school environment
● Communicate clearly with staff and senior leaders
● Leave classrooms tidy and handover notes for the returning teacher
Schools remember supply teachers who make life easier for the permanent staff.
06 Subject Knowledge and Initiative
Even when covering outside your specialism, schools want supply teachers who show initiative and make lessons engaging. If no work is set, being able to deliver a structured activity demonstrates professionalism and competence.
07 Safeguarding Awareness
Every teacher in the UK must prioritise safeguarding, and supply teachers are no exception. Schools look for candidates who understand their safeguarding responsibilities and know how to report concerns appropriately.
Why Supply Teaching Can Be a Great Career Choice
Many of our candidates choose supply work for the flexibility, variety, and opportunity to experience different schools. It’s also a fantastic way for ECTs and experienced teachers to build networks and secure permanent roles — schools often offer long-term contracts to supply teachers who impress.
