Updated June 2026 · England & Wales
When a local authority refuses to carry out an Education, Health and Care (EHC) Needs Assessment for a child or young person, parents and young people have the right to challenge that decision at the First-tier Tribunal (SEND). Form SEND35a is the document used to start that appeal. It sets out who the appeal concerns, why the local authority's refusal is being challenged, and how the appellant would like the Tribunal to handle the hearing. Getting the form right matters, because the Tribunal works to strict time limits and will often reject or delay appeals that are missing key details. This guide walks through each section of SEND35a in plain English, explains the mediation requirement that sits before an appeal, and sets out what to expect once the form has been submitted.

Overview

An EHC Needs Assessment is the formal process a local authority uses to work out whether a child or young person has special educational needs that cannot be met through the usual support available in their school or college, and whether they need an Education, Health and Care Plan to secure that support. The assessment draws on input from parents, teachers, educational psychologists, health professionals and, where appropriate, the young person themselves.

It looks at learning, communication, behaviour, physical needs and emotional wellbeing to build a picture of what support the child requires. If a local authority decides not to carry out an assessment after a request has been made, that refusal can be appealed.

Form SEND35a is the route for challenging a refusal to secure an assessment specifically, and it sits alongside other SEND appeal forms used for different decisions. The appeal is heard by the First-tier Tribunal (Special Educational Needs and Disability), which is independent of the local authority.

Key steps

  1. Check the deadline and obtain your mediation certificate. Before submitting SEND35a, you generally need to contact a mediation adviser and obtain a mediation certificate. The Tribunal usually needs to receive your appeal within two months of the local authority's decision letter, or within one month of the mediation certificate, whichever is later. Missing these windows can mean your appeal is not accepted.
  2. Complete Section 1 with details of the child or young person. This part identifies who the appeal relates to. You will need to give the child's full name, date of birth, gender and age. If the young person is over 16 and making the appeal in their own right, their details go here. Accuracy at this stage helps the Tribunal link your appeal to the correct case.
  3. Set out your reasons for appealing in Section 2. Explain clearly why you disagree with the local authority's refusal to assess. Attach the decision letter and the mediation certificate. If you are filing late or cannot produce a mediation certificate, use this section to explain the circumstances so the Tribunal can consider whether to accept your appeal.
  4. Choose how your appeal is decided in Section 3. The Tribunal can decide some appeals on the papers alone, without an oral hearing, if both you and the local authority agree. A paper decision is often quicker but you lose the chance to speak directly to the panel. Think carefully about which route suits your circumstances before ticking a box.
  5. Complete the remaining sections and submit. Sections 4 to 6 cover any related appeals or disability discrimination claims, the contact details of everyone bringing the appeal, and any advocate or representative supporting you. Check the form is signed, attach all required documents, and send it to the Tribunal by the required deadline using the address on the form.

Common questions

Q Who can use form SEND35a to appeal?
The parent or carer of a child under 16, or a young person aged 16 to 25, can use SEND35a to appeal a local authority's decision not to carry out an EHC Needs Assessment. A representative or advocate can also help complete and submit the form, but the appeal itself must be brought by the person with the legal right to appeal. Schools and settings cannot appeal in their own name.
Q Do I need to try mediation before appealing?
In most cases you must contact a mediation adviser before sending SEND35a to the Tribunal. You do not always have to go through with mediation itself, but you generally need to obtain a mediation certificate confirming you considered it. There are limited exceptions, for example where the appeal relates only to the school or placement named. The adviser can explain whether an exception applies.
Q How long do I have to lodge the appeal?
The Tribunal normally needs to receive your appeal within two months of the date on the local authority's decision letter refusing the assessment. If your mediation certificate is issued later, you usually have one month from the certificate date instead. Late appeals can sometimes be accepted if you give good reasons, but this is at the Tribunal's discretion and should not be relied on.
Q Is there a fee to submit SEND35a?
The First-tier Tribunal (SEND) does not currently charge a fee to bring an appeal. You will, however, need to cover your own costs, such as any independent reports you choose to commission or travel to a hearing. Check the current position on gov.uk before filing, as fee arrangements can change over time.
Q What happens after I submit the form?
The Tribunal will register your appeal and send directions setting out the timetable. The local authority must respond to the appeal, and both sides exchange evidence ahead of the hearing. Many cases are resolved before they reach a hearing, often because the local authority reconsiders its decision. If the case proceeds, you will either attend a hearing or receive a decision on the papers.
Q Can I withdraw my appeal if the council changes its mind?
Yes. If the local authority agrees to carry out the EHC Needs Assessment after you have lodged SEND35a, you can write to the Tribunal to withdraw the appeal. It is sensible to wait until you have written confirmation from the local authority that the assessment will go ahead before withdrawing, so you do not lose your place in the appeal timetable.
Q What if I disagree with the outcome of the assessment itself?
SEND35a is only for appealing a refusal to carry out an assessment. If the local authority does assess but then refuses to issue an EHC Plan, or issues a Plan you disagree with, a different SEND appeal form applies. The Tribunal's guidance and gov.uk list the correct form for each type of decision, so check which situation matches yours.
