How to Turn One Supply Booking Into Regular Supply Teaching Work

If you're back on the supply circuit this week, the first few placements of the term matter more than you might think. Schools are forming their impressions of new supply teachers right now, and those impressions decide who gets called back in October, and who doesn't. Getting regular supply teaching work isn't really about chasing more bookings — it's about turning the bookings you already have into repeat ones.

That shift in thinking matters more than ever. DfE data shows 20,500 occasional teachers were recorded in English schools on census day in November 2025, up from 17,700 the year before. More people are doing short-term and supply work, which means schools have more choice — and the teachers who stand out are the ones they don't have to think twice about rebooking.

Why your first placement at a school sets the tone

Most schools decide whether they'd have you back within the first hour. Not because they're being harsh, but because a supply day is high-pressure for everyone: office staff need to know you'll turn up, the class teacher needs to trust you'll follow their plans, and the leadership team needs one less thing to worry about. Arriving early, checking in properly at reception, and asking sensible questions before the bell goes all signal the same thing — that you're not going to be a problem to manage.

The numbers behind getting rebooked

Repeat bookings tend to cluster around a smaller number of schools rather than being spread thin. NASUWT's 2024/25 survey of supply teachers in England found that 42% of respondents worked in more than five schools over the year, while 23% said the majority of their assignments were longer-term, running beyond a single term. That split is telling: the teachers with longer, steadier placements are usually the ones who made a strong first impression somewhere and were asked back, rather than the ones cycling through the widest possible list of schools.

Secondary schools have an extra reason to want dependable faces this term. NFER's 2026 Teacher Labour Market report found secondary recruitment came in 11% below target for 2025/26, with a similar shortfall forecast for 2026/27. Where permanent recruitment is tight, schools lean more heavily on supply staff they already trust — which is an opening for anyone willing to build a relationship with a handful of secondaries rather than treating every booking as a one-off.

Leave a handover that makes the decision easy

The gap between a one-off booking and being asked back regularly often comes down to what happens at 3.30pm. A short, clear handover note — what was covered, how the class responded, anything the regular teacher needs to know — does more for your chances than almost anything else in the day. It shows you were paying attention, and it gives the school a reason to specifically request you next time rather than "whoever's free."

Small things add up here too: completing any marking before you leave, being straightforward with teaching assistants rather than working around them, and flagging behaviour incidents through the right channel instead of letting them go unrecorded. None of it is dramatic. All of it is remembered.

Build a core group instead of casting a wide net

It's tempting, especially early in the term, to say yes to every booking from every partner in the hope that something sticks. But regular supply teaching work is easier to build with a smaller, deliberate group of schools than with a constantly shifting list.

Once you've built goodwill at two or three schools, it's fair to say so — most staffing partners are happy to note a preference, and some schools will ask to book you directly for future dates. If a school mentions they'd like you back, treat that as an opening to ask about upcoming gaps in their calendar rather than waiting for the phone to ring.
