Recruitment agencies help schools find teachers faster by matching pre-vetted candidates to teaching vacancies within days, not weeks. That speed comes from work finished long before a head of department hands in a resignation letter.
However, the gap between posting an advert and welcoming a new teacher still stretches across weeks in most schools. Your existing staff absorb that gap, covering lessons and marking while the vacancy sits open and the budget drains.
This guide explains how an agency shortens that timeline, which roles it fills, and how the two hiring routes compare. Read it before you write your next advert.
Why Do Schools Struggle to Fill Teaching Vacancies Quickly?
Schools struggle to fill teaching vacancies quickly because advertising, vetting and interviewing fall on people who already carry a full workload. A head teacher writing a job advert at 7 pm is rarely a hiring specialist, and a rushed advert attracts fewer applicants. Applications then arrive thin. If the only two shortlisted candidates withdraw, the school will have to start the whole process again.
Compliance adds another layer once the school picks a candidate. Under safer recruitment rules, the successful applicant needs an enhanced DBS check, references and proof of their right to work in the UK. Some checks come back in days, while others take weeks. A single late reference can delay a start date by weeks (we have seen this drain a spring-term cover budget).
Shortages also hit some subjects and regions harder than others. Secondary maths and science posts can draw very few applicants, and some receive none. The DfE’s ITT census showed secondary teacher training reached only about half its recruitment target in 2023/24.
That gap means fewer new secondary teachers reach schools each September. Head teachers in the North West and South West report similar pressure, particularly in smaller schools with tight budgets.
A Teacher Recruitment Agency Does the Groundwork Before a Vacancy Opens
Most schools only call an agency once a vacancy is already hurting the timetable. The time savings start much earlier than that. Good education recruitment agencies work the market all year, so they keep a live pool of candidates who have cleared compliance. As an education recruitment agency, we split that school staffing groundwork into three parts.
Pre-Vetted Teachers for Primary Teaching and Secondary Teaching
Our recruitment specialists meet and vet candidates every week, long before your advert goes live. They record each teacher’s subject strengths, the year groups they have taught and their availability. A secondary teacher with a strong second subject, such as maths alongside physics, gets matched to vacancies in both.
That early work cuts your reading time. Instead of sorting 40 mixed applications, you review three or four CVs matched to your timetable. Each primary teacher or secondary specialist on that shortlist fits the hours and subjects you need covered. Every candidate has also met a consultant face-to-face (a database keyword search cannot show how someone runs a classroom).
Safeguarding and DBS Checks Handled Before Day One
Safeguarding sits at the centre of education recruitment. Before any candidate meets your pupils, we complete enhanced DBS checks with barred list checks, verify references and confirm the right to work. Keeping Children Safe in Education sets the standard, and we apply it to every SEN teacher, class teacher and support staff placement. Your school then receives written confirmation of those checks, as KCSIE requires, and only needs to verify ID on arrival.
This preparation means a teacher can start on Monday instead of waiting weeks for paperwork to clear. We also ask candidates to join the DBS Update Service, which lets us check their certificate status online with their consent. A single delayed certificate is far less likely to hold up a placement.
Supply Staff Ready for Short Notice Cover
Short-notice cover runs on a different system. Supply teachers register with supply teaching agencies and confirm their availability the evening before each working day. That evening check lets a supply teaching agency book short-term supply within hours of your call.
If you phone at 7 am about a flu outbreak, we will aim to have a qualified supply teacher at reception by 8:30 am.
Business managers tell us they value this service most. Daily cover keeps each class with its own teacher instead of splitting pupils across other rooms. It also protects your teaching staff. When your own teachers supply internal cover, their marking and planning fall behind.
Education Staffing: Covering Every Role from Teaching Assistants to Support Staff
Schools rely on teaching and support roles beyond the class teacher at the front of the room. One education staffing partner can fill most of those posts through a single point of contact. Teaching assistants, cover supervisors and office staff all come from the same vetted pool as our school teachers. Here are the roles schools ask us to fill most often each term:
- Teaching Assistants and HLTAs: A teaching assistant provides general classroom support, while a higher-level teaching assistant can lead whole classes under agreed arrangements. Each SEN TA we place has experience supporting pupils with special educational needs, including in secondary SEN units.
- Cover Supervisors and Invigilators: Cover supervisors keep set work on track and behaviour settled when a teacher is absent. Exam invigilators run the summer series so your staff stay on their own timetables.
- Early Years and Teaching Support: Nursery practitioners join early years and primary settings on day rates or permanent contracts. A Learning Support Assistant works alongside class teachers to help pupils with special needs.
- School Office and Admin Staff: Receptionists, attendance officers and exams officers keep the school day organised. We vet these support staff to the same standard as classroom roles.
Before you call, list every role you are likely to need next term. One partner who supplies teachers and teaching assistants as well as office staff saves you chasing several suppliers each term.
Agency or Solo School Recruitment: How the Two Routes to Education Jobs Compare
Once you know what an agency covers, the next question is how it compares with running school recruitment yourself. Both routes can fill the post, but they differ in speed, cost and who carries the compliance risk. The table below sets out each route side by side. Figures are typical ranges and will vary by subject and region.
| What you’re comparing | Through an agency | Hiring on your own |
|---|---|---|
| Time to shortlist | 24–72 hours | 3–6 weeks |
| Compliance checks | Finished before the CV reaches you | Your admin team chases references |
| Who completes the checks | Agency, with written confirmation to you | Your school, in full |
| Cost shape | Placement fee or agreed day rate | Advert spend plus internal staff hours |
| Short-notice cover | Same-day supply staff | Internal cover only |
Our verdict: direct hiring suits a planned September start with a long lead time. Education recruiters earn their fee when a vacancy opens mid-term and the timetable cannot wait. Most schools we work with use both routes. They hire directly for planned posts, call us for urgent gaps and share next term’s forecast with us early.
Get in Touch to Fill Your Next Teaching Role
Filling a teaching post quickly depends on work done before the vacancy appears. An agency with vetted teaching professionals can send a matched shortlist within 72 hours. A direct search often takes three to six weeks.
Rather than waiting for a resignation letter, map your likely gaps for next term and share them with us early. Strong candidates often accept the first solid offer they receive, so the schools that move first usually secure them.
