One of the most common misconceptions among parents navigating special educational needs in England is that a child must have a formal diagnosis — of dyslexia, ADHD, autism or another condition — before a school can provide any additional support.
This is not the case. The law in England is clear: schools are required to identify and support children with special educational needs (SEN) based on the child's needs, not on whether those needs have been given a clinical label. A diagnosis can be helpful — but it is neither a prerequisite for support nor a guarantee of it.
The SEND Code of Practice 2015 — which remains the statutory framework governing special educational needs in England as of 2026 — states that schools must use their best endeavours to identify children with SEN and put appropriate support in place. Identification is based on observation and assessment of the child's needs, not on a diagnosis from a clinician.
What Is SEN Support?
SEN Support is the term used in the SEND Code of Practice for the help that schools provide to children with special educational needs before an Education, Health and Care Plan (EHCP) is in place. It is the first and most widely used level of support in the system.
Under SEN Support, a school might:
- Provide additional in-class support from a teaching assistant
- Adapt teaching approaches or lesson materials to suit the child's learning style
- Put in place a specific intervention programme (for example, a reading or numeracy group)
- Set targets and review progress more frequently than for other pupils
- Involve specialist staff such as a speech and language therapist or educational psychologist — usually via the local authority
- Create a SEN Support Plan (sometimes called an Individual Education Plan or IEP) setting out the child's targets and the strategies being used
None of these measures requires a clinical diagnosis. What they require is the school — and typically the Special Educational Needs Co-ordinator (SENCO) — to identify that the child has a need and to plan appropriate provision.
How Does a School Identify SEN Without a Diagnosis?
Schools use a range of sources to identify children who may have SEN. Importantly, parental concern is one of them. The SEND Code of Practice explicitly recognises that parents are often the first to notice something and gives weight to parental observations.
Sources schools use to identify SEN include:
- Teacher observation of how the child responds to learning in the classroom
- Assessment data — tracking whether the child is making expected progress compared with peers
- Nursery or previous school reports and early years assessments
- Parent concerns raised in meetings or in writing
- The child's own views about their learning (particularly for older pupils)
- Screening tools administered by the school (for example, literacy or attention screenings)
If evidence from these sources suggests a child has significantly greater difficulty learning than most pupils of the same age, or a disability that prevents or hinders them from accessing the education available to others, the school is expected to identify them as having SEN and begin the SEN Support process.
The Four Areas of SEN
The SEND Code of Practice groups special educational needs into four broad areas. A child can have SEN in one or more of these areas — and again, a formal diagnosis is not required for a child to be identified as having needs in any of them:
| Area | Examples (not an exhaustive list) |
|---|---|
| Communication and Interaction | Difficulties with speech, language, social communication; traits associated with autism spectrum |
| Cognition and Learning | Moderate or severe learning difficulties; dyslexia; dyscalculia; processing difficulties |
| Social, Emotional and Mental Health | Anxiety, emotional regulation difficulties, attention difficulties; traits associated with ADHD |
| Sensory and/or Physical | Visual or hearing impairment; physical disability; sensory processing differences |
A child who is struggling significantly in any of these areas — whether or not they have a diagnosis — should be considered for SEN Support.

What Can Parents Do If the School Is Not Responding?
If you have raised concerns with your child's teacher and feel the school is not taking them seriously, there are clear steps you can take:
Step 1: Request a Meeting With the SENCO
Every school in England is required by law to have a designated SENCO. Ask specifically to meet with the SENCO rather than just the class teacher. Come prepared with specific observations: what you are seeing at home, how your child describes school, any patterns you have noticed in their behaviour or learning. Written notes are more effective than verbal descriptions alone.
Step 2: Ask the School to Put Any Agreement in Writing
If the school agrees that your child needs additional support, ask for the support plan or agreed actions to be put in writing. This does not need to be a formal document — even an email confirming the next steps is valuable. Written records are important if you later need to escalate.
Step 3: Request Formal Identification on the SEN Register
Ask the SENCO directly whether your child is on the school's SEN register. Schools maintain a register of all children identified as having SEN. If your child is on this register, they are formally recognised as having SEN and the school has a duty to plan and review their support systematically.
Step 4: Consider Whether an External Assessment Is Needed
If the school's own resources are not sufficient to identify or address your child's needs, ask whether a referral to an external specialist is appropriate — for example, a speech and language therapist, an educational psychologist, or a paediatrician. These referrals can come through the school, the GP or (in some cases) directly.
External assessments may result in a formal diagnosis — but even if they do not, the report from a specialist can be used to support and refine the school's SEN provision without requiring a diagnostic label.

When Does a Diagnosis Actually Help?
While a diagnosis is not required for SEN Support, it can be useful in several ways:
- It can clarify the nature of the child's needs — helping teachers and SENCOs understand what strategies are most effective
- It strengthens an EHCP application — if a child's needs are complex enough to require an Education, Health and Care Plan, clinical evidence from a diagnostic assessment carries significant weight in the assessment process
- It can access specialist services — some therapists, support groups and local authority provisions are diagnosis-led in practice, even if they are not required to be by law
- It can help the child understand themselves — particularly for older children and teenagers, a diagnosis can bring clarity and reduce self-blame
However, a diagnosis does not automatically result in additional provision, and waiting for a diagnosis before the school takes any action is not appropriate. If the child has an identifiable need now, support should begin now.
The Difference Between SEN Support and an EHCP
SEN Support is the first level of help — provided directly by the school, funded within the school's normal budget. For most children with SEN, SEN Support is sufficient. However, if a child's needs are so significant that they cannot be met through standard SEN Support, families can request an EHC Needs Assessment — the process that may lead to an Education, Health and Care Plan (EHCP).
An EHCP is a legally binding document that sets out the child's needs and the provision required to meet them. It is reassessed annually and can name a specific school — including a specialist setting. Again, a formal diagnosis is not a legal requirement for an EHCP, though in practice, clinical evidence is expected to support the application.

Frequently Asked Questions
My child has no diagnosis but I think they have dyslexia. What should I say to the school?
You do not need to use a diagnostic term to raise the concern effectively. Describe what you are observing specifically: "My child struggles significantly with reading compared to their peers", "They reverse letters regularly", "They cannot retain phonics rules even with repeated practice". These observations are what the school can assess and act on. You can also ask the school to carry out its own literacy screening. If the school identifies a significant need, they can put SEN Support in place without waiting for an external dyslexia assessment.
The school says my child is "fine" but I disagree. What are my options?
Ask the school to show you the evidence for that conclusion — specifically, how your child is performing relative to expected standards, and whether the school has carried out any formal assessment. If you remain concerned, you can request an independent assessment through your GP (for example, a paediatric referral) or pay for a private educational psychology assessment. You can also contact your local authority's SEND Information Advice and Support Service (SENDIASS) — a free, impartial service for families — for guidance on your rights and next steps.
Can a child be on the SEN register without parents being told?
No. Schools are expected to work in partnership with parents. If a child is placed on the SEN register and identified as needing SEN Support, the school should inform parents and involve them in the planning of that support. Parents should also be invited to regular reviews of the support plan. If you are unsure whether your child is on the SEN register, you can ask the SENCO directly — and they must answer you honestly.
Does SEN Support cost the family anything?
No. SEN Support is funded by the school from its core budget, including its dedicated SEND funding. Families are not charged for the provision. External specialist assessments arranged by the school (such as a referral to an educational psychologist through the local authority) are also free. If a family chooses to commission a private assessment, that cost falls to the family — but this is a choice, not a requirement.
My child has just moved schools. Will SEN support continue automatically?
Not automatically in all cases — but the previous school should send the new school a record of the child's SEN and the support that was in place. The new school is expected to continue appropriate support based on that information. However, it is strongly advisable to inform the new school proactively before the child starts, request a meeting with the SENCO, and provide copies of any reports or plans from the previous school. Do not assume the information will transfer seamlessly.
What is SENDIASS and how can it help?
SENDIASS stands for Special Educational Needs and Disabilities Information Advice and Support Service. Every local authority in England is legally required to provide this free, impartial service to children and young people with SEND and their parents. SENDIASS advisers can help you understand your rights, prepare for school meetings, navigate the EHCP process, and escalate concerns if you feel the school or local authority is not meeting its obligations. You can find your local SENDIASS through your council's website or via the IASS network website.
