What Evidence to Gather for an EHCP

Evidence is the single biggest factor in whether an Education, Health and Care Plan (EHCP) case succeeds. Local authorities agree assessments, issue plans, and concede tribunal appeals when the evidence clearly shows a child's needs and the support those needs require. Strong feelings and a well-written letter matter, but they are no substitute for a well-built evidence file.

This guide explains exactly what evidence to gather, where to get it, and how to organise it so your case is as persuasive as possible at every stage, from the initial request through to a SEND Tribunal hearing.

You Do Not Need a Diagnosis First

A common myth is that you need a formal diagnosis before you can apply. You do not. The legal test for an EHC needs assessment is about your child's special educational needs and the provision they require, not about a label. A diagnosis can be helpful supporting evidence, but its absence is never a lawful reason for a council to refuse to assess. Our guide on whether you qualify for an EHCP explains the threshold in plain English.

The Core Categories of Evidence

A strong EHCP file usually draws on several types of evidence. The more of these you can include, and the more specific they are, the stronger your case.

Educational psychology reports

An educational psychologist (EP) report is often the most influential single document. A good EP report assesses cognitive ability, identifies specific areas of difficulty, and recommends provision that is detailed and quantified. The local authority should commission one as part of an assessment, but you can also obtain an independent EP report yourself. When a council report is thin or vague, an independent one often tips the balance.

Therapy and health reports

Depending on your child's needs, reports from a speech and language therapist, occupational therapist, physiotherapist, paediatrician or mental health professional can be vital. These reports should set out the need, the impact, and the specific therapy or support recommended. The distinction between health provision and educational provision matters, so read our guides on speech and language needs and sensory processing to understand why some therapy belongs in the enforceable part of the plan.

School data and records

Evidence from the school is powerful because it shows need over time and in context. Gather:

• Attainment and progress data, especially anything showing a widening gap between your child and their peers
• The SEN support plan and any records of the assess, plan, do, review cycle
• Behaviour and incident logs, attendance records, and pastoral notes
• Examples of work that show the difficulties your child faces

If your child is currently on SEN Support rather than a plan, our guide on EHCP vs SEN Support explains how to show that school-level help is not enough.

Your parental statement

Your written account is evidence in its own right. You see your child across every setting, not just the classroom. A strong parental statement describes the daily reality, the impact of difficulties on learning and wellbeing, what has been tried, and what you believe your child needs. Be specific and factual rather than emotional, and link what you describe to the kind of provision you are asking for.

Independent Reports: When They Are Worth It

You are entitled to commission your own independent reports, and at tribunal these can be decisive. An independent EP report that quantifies need and recommends specific provision is one of the most powerful documents in any bundle. They are optional and you pay for them, so weigh the cost against the strength of your case. If the council's reports are weak or fail to recommend specific provision, an independent report often makes the difference.

Whatever evidence you gather, the goal is provision that is specific and quantified. Vague wording is the most common reason support becomes unenforceable, so read our guide on Section F specificity to understand what good provision wording looks like and steer your experts towards it.

How to Organise Your Evidence

Good evidence loses its force if it is disorganised. Whether you are submitting an assessment request or preparing a tribunal bundle, organise your file so the reader can follow it easily.

• Make a contents list. Number and date every document so it can be referred to quickly.
• Order it logically. A clear history followed by the most recent and most authoritative reports works well.
• Write a short covering summary. One or two pages explaining what the evidence shows and what you are asking for guides the reader to the right conclusion.
• Keep copies of everything, with dates of every letter sent and received, so you can show the full picture and track deadlines.

This same evidence carries you through the whole process. To see how it fits together, read our guides on the EHC needs assessment and on appealing to the SEND Tribunal, where a well-organised bundle is what wins cases.
