What Supply Teachers Should Know About SEND Classrooms
Walking into a new classroom is always a little unpredictable. Walking into a Special Educational Needs and Disabilities (SEND) classroom as a supply teacher, sometimes with less than an hour’s notice, can feel genuinely daunting — even for experienced practitioners.
The truth is that with the right preparation and the right mindset, supply teachers can make a real and positive difference in SEND settings. This guide covers the essentials: your legal responsibilities, how to adapt quickly, working with Teaching Assistants (TAs), communication strategies and where to find further training and support.
At First Class Supply, we work hard to match teachers with placements where they can thrive. If you are considering SEND supply work or have been placed in an inclusive setting, read on.
What Are Your Legal Responsibilities in a SEND Classroom?
As a supply teacher, you carry the same duty of care as any other member of teaching staff. That includes upholding the rights of pupils with SEND under the Children and Families Act 2014 and the SEND Code of Practice, which sets out how schools must identify, assess and support pupils with additional needs.
The most important document to be aware of is the Education, Health and Care Plan (EHCP). An EHCP is a legally binding document for pupils with more complex needs. It outlines their specific requirements, the support they must receive and any adaptations the school is required to make. You will not always have time to read an EHCP in full on the day, but you should ask the SENCO (Special Educational Needs Coordinator) or your TA to brief you on the key points before the lesson begins.
Your safeguarding duties also remain fully in place. If you have any concerns about a pupil’s welfare, follow the school’s reporting procedure immediately. Our guide on how to handle EHCPs as a supply teacher goes into more detail on navigating these documents confidently.
What Should You Find Out Before the Lesson Starts?
A quick, focused handover can make an enormous difference to how your day goes. If you can speak to a TA, SENCO or class teacher before the lesson, try to find out:
- Which pupils have EHCPs or are on the SEND register
- Any specific triggers, sensory sensitivities or medical needs to be aware of
- Communication methods used by individual pupils (Makaton, picture cards, AAC devices)
- Behaviour support plans or positive handling agreements in place
- Any pupils who may need a quiet space, movement breaks or sensory tools
- The role your TA will play and how they prefer to work alongside you
Even two or three minutes of conversation can give you the context you need to start the day safely and confidently. For more on building that relationship quickly, read our article on working with Teaching Assistants as a supply teacher.
How Can You Adapt Your Teaching for SEND Pupils?
You do not need a full week of planning to teach inclusively. Small, thoughtful adjustments make a significant difference for pupils with a wide range of needs.
Practical Classroom Adjustments
- Reduce sensory overload: dim bright lights where possible, minimise background noise and avoid standing in front of busy displays when giving instructions
- Use clear, simple language: give one instruction at a time and allow processing time before repeating
- Offer choice and predictability: let pupils know what is coming next; even a simple visual timetable on the board helps reduce anxiety
- Provide movement breaks: some pupils regulate better with short, structured breaks rather than extended sitting time
- Use visual supports: write key words on the board, use pictures or symbols alongside text, and keep resources clearly labelled
Differentiating on the Day
You will rarely have pre-differentiated resources for a supply placement, but there are quick adjustments you can make. Offer tasks in chunks rather than all at once. Allow verbal responses instead of written ones where appropriate. Pair pupils thoughtfully for group activities, or allow independent work with TA support for those who need it. Our article on adapting lessons for SEND pupils on supply offers ready-to-use strategies for common classroom scenarios.
How Should You Approach Behaviour in SEND Settings?
This is one area where supply teachers often feel least confident. It is important to understand that behaviour is usually communication. A pupil who is shouting, withdrawing, refusing to engage or becoming distressed is almost always telling you something about how they are feeling, not deliberately causing problems.
Avoid escalating confrontations. In SEND settings, a calm, low-key response is almost always more effective than a firm or authoritative one. Redirect rather than reprimand, offer an alternative rather than a removal, and always involve your TA if a situation is becoming difficult.
Our article on behaviour versus additional needs is well worth reading before any SEND placement to help you distinguish between behaviour that needs a consequence and behaviour that needs support.
What Communication Strategies Should You Know?
Many pupils in SEND classrooms use communication methods beyond spoken language. You do not need to be a specialist to respond appropriately, but some basic awareness helps.
- Makaton is a language programme using signs and symbols alongside speech, widely used in primary SEND settings
- AAC (Augmentative and Alternative Communication) devices range from low-tech picture boards to high-tech speech-generating tablets
- PECS (Picture Exchange Communication System) involves pupils exchanging picture cards to communicate needs or requests
If a pupil uses one of these systems, your TA will usually guide you. Never remove or discourage a pupil’s communication tool, even if it feels unfamiliar. For a broader introduction to supporting pupils with additional needs, visit our article on how to support SEN pupils as a supply teacher.
Where Can You Find SEND Training and CPD?
If you are keen to take on more SEND placements, or simply want to feel better prepared, there are excellent training options available.
The nasen (National Association for Special Educational Needs) offers free and low-cost professional development resources specifically for teachers. The Council for Disabled Children also provides practical guidance on inclusive practice.
First Class Supply has a dedicated article covering training options for supply teachers interested in SEN, and you can explore whether specialist SEND supply is right for your career in our guide is SEND supply teaching right for you? We also cover how SEND experience can improve your teaching career if you are thinking about the longer term.
How First Class Supply Supports Teachers in SEND Settings
We know that SEND placements require a particular kind of support from an agency. That means giving you relevant information ahead of a booking, being honest about what a setting involves and making sure you never feel thrown in at the deep end without a word of warning.
Our team takes the time to understand your experience and confidence level before recommending placements. We place teachers across a wide range of settings in the North East, including specialist provision and alternative provision schools. You can read more about those settings in our article on supply teaching in specialist and alternative provision settings.

Schools can find out more about how we match quality supply staff on our information for schools page.
If you are ready to register or want to have a conversation about SEND placements, get in touch with our team or follow our step by step registration guide to get started. You can also find further resources and community support on our news and community pages.
