TL;DR: There are many routes into supply education. And not all of them require advanced degrees or specialised training. You can absolutely start a career (or transition) into supply education if you take the right first steps.

How to become a supply teacher is a common search term. But “supply teacher” doesn’t properly reflect all of the different roles you can work in supply education. 

Supply educators work in schools, nurseries, and special provisions. They may be qualified teachers, cover supervisors, nursery practitioners, or support staff.

So whether you’re just starting out or looking to return to education, this guide will help you understand how to start supply teaching, the different steps to becoming a supply teacher, what you need to work in schools, and the qualifications for classroom work in both school and nursery settings.

Supply work in schools covers a variety of roles — from full classroom teaching to vital support positions. Here’s what you need to know:

1. Qualified Teacher (QTS)

This is the most recognisable type of supply role.

• Qualifications for classroom work: You’ll need Qualified Teacher Status (QTS), typically obtained via a PGCE, SCITT, or other approved route.
  📚 GOV.UK – QTS Guidance
• Roles can be day-to-day or longer-term assignments.
• Available across primary, secondary, and special school settings.
  

2. Cover Supervisor

For those without QTS but who have a strong classroom presence.

• What you need to work in schools: Usually a degree and a minimum of three months’ experience working with young people in an organised environment.
• No requirement to teach new material — you supervise and ensure students complete assigned work.
• Popular for aspiring teachers or career changers.

3. Teaching Assistant (TA) / Learning Support Assistant (LSA)

Support roles that make a big impact in the classroom.

• Qualifications for classroom work: Not mandatory, but Level 2 or 3 TA qualifications are valued.

Work includes one-to-one support, small group intervention, or SEN-focused help.

Supply nursery work is vibrant, hands-on, and nurturing. It also offers great opportunities to build your career in early years.

1. Qualified Nursery Practitioner

These roles are for those with formal childcare training.

• Qualifications for classroom work: A Level 2 or 3 early years qualification from the DfE’s approved list.
  📚 GOV.UK – Full and Relevant Qualifications
• You might lead a room, manage a key group, or plan EYFS-based activities.

2. Unqualified Nursery Assistant

Perfect if you have experience but no formal qualifications yet.

• What you need to work in schools (or nurseries): Prior experience with under-5s is often enough.
• You’ll help with play, meals, nappy changing, and daily routines.

A great entry route for those considering formal training in the future.

No matter your role or setting, there are universal steps to begin your supply journey.

1. Apply to an Agency

• Most supply work is coordinated through specialist agencies.

• They’ll handle your vetting, placements, and support.

2. Registering for Teaching Roles

• Submit required documents: CV, references, proof of qualifications, right to work, and an enhanced DBS check.

• For early years roles, paediatric first aid may be required.

3. Steps to Becoming a Supply Teacher

• Tailor your CV to match the role you’re aiming for — whether in schools or nurseries.

• Be clear on your availability and travel range.

Working flexibly in schools and nurseries allows you to build experience across different ages and settings while keeping control over your schedule.
