In a competitive job market where lots of Early Career Teachers (ECTs) are looking to secure their first teaching post, it can be easy to get overwhelmed searching for a job once you’re qualified.
Whilst many ECTs focus on finding a permanent post, those who understand and use temporary opportunities strategically often significantly improve their chances of securing  their first role and reduce their stress levels in the process.

Understanding the job market

The teaching job market is cyclical and competitive, particularly for permanent roles. Many schools:

  • recruit internally where possible,
  • offer temporary contracts before committing to permanent hires, or
  • use supply staff to ‘trial’ potential candidates.

This means waiting for the ‘perfect permanent job’ can limit your opportunities as an ECT. Being flexible and open to temporary roles often leads to faster entry into the profession.

Why supply agencies are a smart choice

Taking a temporary position is a smart move. With many schools preferring to appoint teachers they know to permanent roles, supply work can be the foot in the door you need.

As well as helping you transition into a permanent post, working on supply can help you:

  • Gain classroom experience quickly
  • Build confidence across year groups
  • Demonstrate your skills in a real school environment
  • Expand your professional network
  • Keep your training up-to-date through school and agency led CPD sessions

Types of temporary roles to consider

There are different types of temporary roles available, ranging from day-to-day supply through to long-term maternity covers. Day-to-day supply is great for those looking to experience lots of different schools, where long-term roles offer more stability and often come with the option of starting/completing your induction.

It’s up to you which one you pick, and we’re here to support you either way.

When to start your search

There is a misconception that if you’re looking for long-term supply you’ll be waiting around until late August to be offered a teaching post for September. The reality is most schools like to be organised and will look to fill their vacancies before they break up for summer.

Starting your search and registering with an agency during the spring/early summer term will ensure you’re in the best position to secure a September start.

But what if you’ve missed the boat? That’s okay! We often deal with last-minute vacancies and find opportunities for ECTs are available all year round.

How to secure the best temporary role for you

Schools need temporary staff who can hit the ground running. When applying, highlight qualities that suit flexible positions:

  • Adaptability across year groups
  • Strong behaviour management
  • Ability to build relationships quickly
  • Confidence delivering pre-planned lessons
  • Willingness to contribute immediately

Using supply teaching strategically

If you choose supply work, treat every day as an extended interview:

  • Arrive early and be prepared
  • Follow school routines carefully
  • Leave clear feedback for teachers
  • Be positive and professional with staff and students
  • Express interest in returning
  • Where possible, introduce yourself to senior leaders – you want to be remembered by those making staffing decisions

Staying positive in a flexible job market

Temporary roles can feel uncertain, but they build momentum. Each placement:

  • Strengthens your CV
  • Expands your experience
  • Improves your confidence
  • Increases your visibility
