How to Challenge Your School's Interpretation of an EP Report

If your school is telling you your child's EP report shows "nothing to worry about" but you suspect the scores tell a different story, you're almost certainly right to question it. Schools routinely minimise EP data — not always maliciously, but because gatekeeping statutory assessments protects budgets. Here's how to identify when the school's interpretation contradicts the clinical evidence, and exactly what to do about it.

The key principle: you don't need a medical degree to challenge a school. You need the test publisher's own scoring classifications and the statutory language that triggers an assessment obligation. Both are fixed, published standards — not matters of professional opinion.

The Three Most Common Minimisation Tactics

Tactic 1: Relabelling Clinical Classifications

The most frequent tactic is describing a "Very Low" score as "low average" or "a little below where we'd expect." When a SENCo tells you a Standard Score of 78 is "low average," they're using colloquial language to soften a clinical classification. The Wechsler scoring manual — the standard used by the WISC-V, the most commonly administered cognitive assessment in UK educational psychology — classifies 78 as "Very Low." That means your child falls at the 7th percentile: 93% of children their age perform better.

What to say in the meeting: "Can you confirm which descriptive classification the test publisher assigns to a Standard Score of 78? My understanding is that the WISC-V manual classifies that as 'Very Low,' not 'low average.' Could you explain why you've used a different classification?"

Tactic 2: Hiding Behind Composite Scores

Schools frequently cite the Full Scale IQ (FSIQ) or a General Ability Index (GAI) and declare the child "average overall." But composite scores are averages of component indices — and an average of a high score and a very low score can mask a clinically significant disability.

A child with Verbal Comprehension at 112 (High Average) and Processing Speed at 78 (Very Low) has a composite that falls in the Average range. But the 34-point gap between those two domains is well beyond the 15-point threshold widely accepted as a clinically significant discrepancy. The child has a specific processing deficit that the composite completely obscures.

What to say in the meeting: "I understand the composite score is in the Average range, but I'd like to discuss the index-level scores individually. There appears to be a significant discrepancy between [Domain A] and [Domain B]. Can we discuss what that gap means for my child's daily functioning in the classroom?"

Tactic 3: Citing Behaviour Rather Than Data

Some schools pivot from the clinical data entirely: "But your child is coping well in class" or "They're not disruptive, so we don't think they need additional support." This conflates compliance with capability. A child who sits quietly while understanding nothing is not "coping well" — they're masking. And the EP data, not classroom behaviour, is the clinical evidence.

What to say in the meeting: "I appreciate the observation about classroom behaviour, but the EP assessment measures cognitive processing and academic potential, not classroom compliance. A child can be quiet and still have a processing speed at the 7th percentile. Can we discuss what the test data shows rather than behavioural observations?"

Building Your Evidence Case

Challenging the school's interpretation is the first step. The next step is using the EP data to build a formal request for statutory assessment — whether that's an EHCP (England), IDP (Wales), CSP (Scotland), or Statement (Northern Ireland).

Step 1: Extract the Key Scores

Go through the EP report and list every Standard Score, Percentile Rank, and Scaled Score. Identify:

• Any Standard Score below 85 (below average)
• Any Standard Score below 70 (extremely low — almost always qualifies for statutory intervention)
• Any discrepancy of 15+ points between cognitive indices
• Any Scaled Score below 7 on individual subtests (below average)
• Any T-Score above 60 on behavioural assessments (at-risk threshold)

Step 2: Compare Against the Test Publisher's Classifications

Use the published classification tables — not the school's paraphrasing. If the EP report says "Standard Score: 78" and the school says "low average," you can point to the WISC-V Technical and Interpretive Manual, which classifies 70–79 as "Very Low."

Step 3: Document the School's Interpretation

Write down exactly what the SENCo or teacher said about each score during the meeting. If they described a Very Low score as "fine," that's evidence of institutional minimisation that strengthens your case at tribunal.

Step 4: Submit Your Assessment Request

Your formal letter to the local authority should cite the specific EP scores, the clinical classifications, and the discrepancies — not the school's verbal summary. The statutory threshold in England is that the child "has or may have SEN" and "it may be necessary for special educational provision to be made in accordance with an EHC plan." Clinical data showing scores in the Very Low range meets this threshold.

The United Kingdom SEN Assessment Decoder includes jurisdiction-specific letter templates with the correct legal trigger phrases for England (Section 36, Children and Families Act 2014), Wales (ALNET Act 2018), Scotland (ASL Act 2004), and Northern Ireland (Education Order 1996), plus the evidence summary format that forces a written response.

What If the School Refuses to Act?

Schools cannot prevent you from requesting a statutory assessment. In England, parents have an independent legal right to request an EHC needs assessment directly from the local authority, bypassing the school entirely. The same applies in Scotland (parents can request a CSP assessment under the ASL Act 2004), Wales (parents can request LA involvement if the school refuses to identify ALN), and Northern Ireland (parents can request statutory assessment directly from the Education Authority).

If the local authority also refuses, you have the right to appeal to the relevant tribunal:

In England, 98% of tribunal hearings find partly or wholly in favour of parents. The odds are overwhelmingly in your favour — authorities rely on parents not knowing this.

Who This Is For

• Parents who've attended a school meeting where the SENCo downplayed EP report scores and who need the clinical language to push back
• Parents holding an EP report with scores below 85 whose school is refusing to escalate to statutory assessment
• Parents who suspect the school is using "masks well" or "coping in class" to avoid triggering an expensive assessment
• Parents whose local authority has refused an assessment request based on the school's interpretation rather than the raw clinical data
• Parents in any UK nation — the psychometric scoring is identical across England, Wales, Scotland, and Northern Ireland

Who This Is NOT For

• Parents whose school is genuinely supportive and proactively requesting statutory assessment
• Parents whose child's EP scores are genuinely in the Average range with no significant discrepancies
• Parents looking for advice on how to get an EP assessment in the first place (see our guide to SEND assessment in the UK)

Frequently Asked Questions

Can a school legally refuse to share the EP report with parents?

No. Parents have a legal right to a copy of their child's EP report. If the assessment was commissioned by the school or local authority, you can request the full report under the Data Protection Act 2018 (Subject Access Request). If the school shares only a summary, insist on the complete document with all numerical data.

What if the school's EP and my private EP disagree?

Private EP reports carry equal legal weight to local authority reports at tribunal. If the school's EP minimises difficulties and your private EP identifies significant needs, the tribunal will consider both — and the one with more detailed, quantified recommendations typically carries more weight. Ensure your private EP is HCPC-registered and follows tribunal practice directions.

Is it worth challenging the school or should I just go straight to the local authority?

Both. Challenge the school's interpretation in writing (email creates a paper trail) and simultaneously submit your own assessment request to the local authority. You don't need the school's agreement to request a statutory assessment. The formal request starts the statutory clock — the LA has 6 weeks to decide whether to assess.

What if the SENCo says the school can provide adequate support without a statutory plan?

Ask for specifics in writing: what support, how many hours, delivered by whom, measured against what outcomes, reviewed on what timeline. If the school can genuinely provide adequate support at SEN Support level, that's fine. But "we'll keep an eye on it" is not a provision plan, and you're within your rights to request statutory assessment regardless of what the school offers.

How do I know if the EP report actually supports a statutory assessment request?

Look for: any Standard Score below 85, any discrepancy of 15+ points between cognitive indices, any recommendation for specialist provision the school cannot deliver from its own resources (e.g., speech therapy, occupational therapy, 1:1 specialist teaching). If the EP report contains any of these, you have clinical grounds for a statutory request — regardless of how the school characterises the findings.
