Working in a Secondary School
Secondary schools are a different environment to primary. The structure, the students, and the expectations are all distinct. This article explains what to expect so you can walk in prepared and confident.
How the day is structured
Secondary schools run on a subject-based timetable. Unlike primary, where students stay with one teacher, secondary students move between rooms and teachers throughout the day depending on the subject. The day typically begins and ends with a form period — a short registration session with a tutor group — which is different to the primary structure most candidates will be familiar with.
Break times are generally shorter than in primary settings.
Finding your way around
Secondary schools are organised by year groups, departments, and faculties. Classes can be in very different parts of the school depending on the subject — your form time might be in the English block while your next lesson is in the Science block. Being able to navigate the school confidently matters, especially early in the day.
When you arrive, report to Reception or the SEN administrator. You will typically be given a welcome pack containing a map of the school, a timetable for the day, any resources for your lessons, and access to a laptop. Read through it carefully before your first lesson. At the end of the day, return to the same point, hand back any equipment, and complete any necessary handover.
The students
Secondary-age students are navigating their path toward independence, which can surface more complex behaviour than candidates might expect from a primary setting. Classes can be higher energy, noisier, and there may be more moments of defiance or conflict.
That said, secondary students respond well to supply staff who make an effort to engage with them directly. Speaking to students personally, building even a brief rapport, and demonstrating that you know the school — the names of heads of year, the headteacher, how things work — goes a long way. Students are less likely to test someone who clearly knows what they are doing and where they are.
The most common mistake first-timers make is staying detached. A purely transactional approach tends to make things harder, not easier.
What to expect from behaviour:
Typical — students talking during lessons. This is normal and generally within acceptable bounds.
Challenging — overt defiance or a consistent refusal to engage. Use the school's behaviour management process if this continues after a calm, direct conversation with the student.
Not acceptable — bullying, intimidation, or harassment. These are non-negotiable and covered by every school's behaviour policy. Read the policy before your booking where possible.
When a student is being disruptive, try to connect with them first. Help them recognise their behaviour is a choice, calmly outline what should be happening, and give them space to make the right decision. If that doesn't work, escalate through the school's process. Always keep your response proportionate to the situation.
What the role involves
Supply teachers hold QTS and are expected to deliver lessons to a high standard — managing the class and teaching the content. Lesson plans and resources are usually provided, but not always. Having a backup activity ready is good practice for any secondary booking in case nothing has been left.
If you are covering a subject outside your specialism, be honest with students if you don't know an answer. Modelling how to find the correct answer — reading carefully, thinking it through — is far more effective than bluffing. Students respond well to that honesty.
Cover Supervisors do not require QTS. The primary responsibility is to manage behaviour and distribute the materials left by the class teacher. The bar for lesson delivery is lower, but maintaining order is still your responsibility.
Teaching Assistants in secondary schools vary considerably. Some roles are 1:1 support for a student with an EHCP. Others involve in-class academic support, literacy or numeracy intervention, or small group work. Expect more variety and less predictability than a primary TA role, and clarify the nature of the role before the booking where possible.
Practical things to know
Dress code — secondary schools generally expect a slightly more formal standard than primary. Shirt and trousers as a minimum, and some schools encourage or require a tie for supply teachers. Check the school's expectations in advance where you can, and when in doubt, dress more formally rather than less.
Technology — expect to use interactive whiteboards. School digital systems and registers vary and can feel unfamiliar at first. Your welcome pack should cover what is expected, and school staff will be on hand to help. Don't be alarmed if systems feel new initially.
Is this role right for you?
Secondary school work suits candidates who are confident, adaptable, and can build quick rapport with older students. If you enjoy working with young people at a more independent stage of their development and can hold your own in a lively environment, secondary supply can be genuinely rewarding.
