Supply Teacher Application Guide
What agencies and schools look for from supply teachers — QTS, flexibility, behaviour management, KCSIE compliance.
**TL;DR.** Supply teaching applications are usually through an agency rather than direct to a school, but agencies and schools look for the same core evidence: QTS, adaptability across phases and subjects, strong behaviour management in unfamiliar classes, KCSIE compliance, and DBS currency.
What agencies and schools look for
- QTS (some agencies accept unqualified teachers for cover roles)
- DBS enhanced clearance
- Adaptability — phases, key stages, subjects you can cover
- Behaviour management with classes you do not know
- KCSIE awareness and disclosure of any concerns
Worked paragraph (180 words)
*Adaptability and behaviour management (essential).* Over the last two years I have taught as a supply teacher across eight primary schools in my local authority, covering Year 1 to Year 6 including three Year 6 SATs revision days and several longer-term maternity cover bookings. I arrive 30 minutes before registration, familiarise myself with the school's behaviour policy, read class notes the regular teacher has left, and identify any pupils with SEN or safeguarding flags. In unfamiliar classes I establish routines quickly using simple signals, consistent phrasing, and positive narration. Schools have rebooked me repeatedly, and one headteacher invited me to apply for a permanent role.

Frequently asked questions
Do I need to register with an agency for supply teaching?
Most supply teaching is through agencies. Some schools and local authorities run their own supply pools. Teaching Vacancies sometimes advertises longer-term supply and cover roles directly.
