Schools hiring through agencies look for teachers who tick certain boxes: recognised qualifications, classroom readiness, and clean safeguarding checks.
Between 30% and 33% of teachers leave the profession within their first five years, so schools in England can’t afford hiring mistakes. They need candidates who’ll stick around, handle the classroom well, and settle in quickly. Agencies act as the first filter in this case, so understanding what schools care about gives you an advantage.
In this article, we’ll cover the qualifications schools won’t budge on, the classroom experience that gets you shortlisted, and the paperwork that stops applications cold. We’ll also look at why availability separates two equally qualified candidates.
Let’s find out what puts you ahead as a teaching candidate.
Teacher Hiring Criteria: What Makes a Candidate Stand Out?
Schools look for recognised UK teaching qualifications, particularly Qualified Teacher Status, and degree credentials that match the subject or age group you’ll teach. We’ve placed teachers in London schools for nearly two decades, and qualifications always get checked first.
Here’s what schools prefer in a candidate’s resume.
Qualified Teacher Status (QTS) and Recognised Training
The main advantage of holding Qualified Teacher Status (QTS) is that it opens doors to maintained schools immediately without additional teacher training requirements. You’d think overseas experience would count as equivalent to UK training, but it doesn’t.
QTS is mandatory for most state-funded secondary schools and primary settings. Meanwhile, a PGCE (Postgraduate Certificate in Education) adds credibility, but isn’t always required for every teaching position.
International teachers need UK recognition of their qualifications, which can take weeks to process through official channels. Usually, this involves submitting your teacher training course documentation and degree alongside other paperwork.
In some cases, the Department for Education may direct candidates to complete an equivalent teacher training course before schools will consider them.
Subject Specialism and Degree Requirements
Does your degree subject need to match what you’ll teach in the classroom?
Secondary schools prefer candidates whose bachelor’s degree aligns with the subject they’ll be teaching. For instance, shortage subjects like maths, science, and modern languages often get faster placements and better contract terms because of high demand.
There’s also scholarship funding available for certain maths and science teacher training courses, which can support candidates still working through their university qualification.
In the meantime, primary teachers need broader subject knowledge across the curriculum, but those who teach primary with a specialism in phonics or SEN (Special Educational Needs) increase their appeal significantly when schools review applications.
Can You Prove Classroom Readiness for Your Teaching Job?
Schools prioritise recent UK classroom experience, particularly roles where you’ve managed behaviour independently and delivered curriculum content across multiple year groups.
In our experience placing teachers across London since 2006, the teaching jobs that fill fastest go to candidates with proven track records in similar settings.
Take a look at the skills hirers look for:
- Recent UK Teaching Experience: Institutions value candidates who already understand the national curriculum, assessment requirements, and how pupils respond to different teaching approaches. Your first teaching job in England can even impress schools more than a decade of international experience.
- Behaviour Management Skills: Managing student behaviour independently proves you can handle real classroom challenges without constant support from senior staff. Secondary schools and primary settings both look for teachers who maintain order whilst keeping children engaged in learning.
- Curriculum Delivery: Adapting your teaching style across different year groups demonstrates flexibility that many schools find valuable when filling vacancies. Teachers who can create engaging teaching materials from scratch show schools they’re prepared to go beyond the basics.
- Career Progression: Candidates who’ve moved from training positions to established roles show commitment to the profession. Local education authority schools in particular look for candidates who show long-term commitment to education in their area.
Schools don’t expect perfection, but they do expect evidence you can manage a classroom from day one. That’s what separates candidates who get interviews from those whose applications sit unread.
Background Checks and Compliance: The Non-Negotiables
Every teacher working with students under 18 must pass enhanced DBS (Disclosure and Barring Service) checks. They also need to provide proof of their right to work in the UK before schools will consider them (delays here cost you placements whilst other candidates move ahead).
Below you’ll see what you should sort before applying.
DBS Clearance and Safeguarding Requirements
Enhanced DBS checks show your criminal record history, and schools need to see a clear certificate (yes, even for day-to-day supply roles). The barring service maintains lists of individuals prohibited from working with children and young people, so schools verify this before confirming any teaching position.
Update Service registration keeps your DBS current across multiple placements without repeating the full check process. In the meantime, safeguarding training must be current, and most schools expect Level 1 or 2 certificates completed recently.
Concerns raised by parents about safeguarding are taken seriously, which is why institutions confirm these checks without exception.
Right to Work and Visa Documentation
Having your visa documentation ready speeds up agency registration and means schools can contact you for placements without delays. In general, non-UK citizens need valid work visas, and Skilled Worker sponsorship isn’t available for all teaching job positions across different locations.
Agencies typically verify your right to work before presenting you to schools, so bring original documents straight away.
Visa restrictions on working hours or contract types can limit which placements you’re eligible for when you apply during the application process. In some cases, candidates may need to explore equivalent overseas qualifications recognition before they can apply for roles in other schools across England.
Availability and Flexibility: Why Schools Pick Certain Candidates First
We’ve found through working with hundreds of schools that availability and flexibility often become the deciding factors once qualifications and checks are complete. There are some valid reasons for that:
- Immediate Start Dates: Teachers who can start immediately get priority over those with lengthy notice periods at current schools. Schools searching for candidates to fill teaching vacancies need coverage now, instead of in six weeks.
- Geographic Flexibility: Willingness to travel across different London boroughs opens up more placement opportunities than sticking to one location. Candidates who limit their search to a single area often miss out on equivalent positions just a few miles away.
- Contract Type Openness: Schools value applicants who accept both day-to-day supply and longer-term contracts rather than being picky about duration. Plus, teachers with the ability to develop skills across different contract types build stronger career prospects over time.
- Year Group Adaptability: Being interested in working across multiple year groups or grade levels shows schools you’re versatile. It demonstrates the kind of flexibility that gives life to a teaching career and makes you valuable to schools needing cover.
Schools need teachers who fit their immediate needs. Ultimately, flexibility is the main reason two candidates with identical qualified teacher status don’t always get treated the same.
Ready to Meet What Schools Are Looking For?
Meeting teacher hiring criteria is mostly about proving you can handle the classroom, work within safeguarding frameworks, and adapt to different school environments.
Schools hiring through agencies in England rely on these filters because they need teachers who’ll make an immediate impact. So, start with:
- Getting your paperwork sorted
- Highlighting relevant teaching experience in your recruitment profile
- Showing your passion for supporting pupils
If your qualified teacher status, compliance checks, and availability align with what schools prioritise, you’re already positioned better than other candidates.
