SEN Assessments: A Complete Guide for Parents

Why Assessment Matters

A formal assessment and diagnosis can:

• Provide understanding: Finally explaining why your child experiences the world differently
• Access support: Many interventions and accommodations require a formal diagnosis
• Inform education: Help teachers understand how best to support your child
• Enable EHCP applications: Professional assessments are crucial evidence for Education, Health and Care Plan requests
• Access benefits: Disability Living Allowance and other support may require diagnostic evidence
• Build self-understanding: For the child themselves, diagnosis can bring relief and self-acceptance

Types of Assessment

Autism Spectrum Assessment

Autism assessments typically involve:

• Developmental history: Detailed interview about early development, milestones, and current functioning
• Observation: Clinical observation of the child, often using standardised tools like ADOS-2
• Questionnaires: Parents, teachers, and sometimes the child complete standardised questionnaires
• Cognitive testing: Often included to understand the child's overall profile

Assessment should follow NICE guidelines and be conducted by professionals with specific autism expertise. A comprehensive assessment typically takes several hours across multiple appointments.

ADHD Assessment

ADHD assessments include:

• Clinical interview: Detailed history of attention, hyperactivity, and impulsivity symptoms
• Rating scales: Standardised questionnaires completed by parents and teachers (e.g., Conners scales)
• Observation: Clinical observation during assessment
• Computerised tests: Some clinicians use continuous performance tests like QbTest
• Rule out other causes: Checking that symptoms are not better explained by other conditions

Dyslexia Assessment

Dyslexia assessments examine:

• Reading accuracy and fluency: Single word reading, passage reading, and comprehension
• Spelling: Patterns of errors and strategies used
• Phonological processing: Ability to manipulate sounds in words
• Working memory: Holding and manipulating information
• Processing speed: How quickly information is processed
• Underlying cognitive abilities: To differentiate specific learning difficulty from general learning needs

A full diagnostic assessment should be conducted by a qualified psychologist or specialist teacher with Assessment Practising Certificate.

Other Specific Learning Difficulties

Similar assessment processes exist for:

• Dyscalculia: Mathematical processing and number sense
• Dyspraxia (DCD): Motor coordination and planning, usually assessed by occupational therapists
• Developmental Language Disorder: Assessed by speech and language therapists

Educational Psychology Assessment

Educational psychologists provide comprehensive assessments that:

• Evaluate cognitive abilities and learning potential
• Identify specific strengths and weaknesses
• Assess social, emotional, and behavioural functioning
• Recommend educational interventions and support
• Provide crucial evidence for EHCP applications

EP reports are often the most useful single document for educational planning and EHCP requests.

NHS Assessment Pathway

How to Access NHS Assessment

1. Speak to your GP: Describe your concerns and request a referral to the appropriate service
2. School SENCO: Can sometimes refer directly to certain services, including educational psychology
3. Health visitor (for under 5s): Can refer to child development services
4. Self-referral: Some services accept direct referrals from parents

Current NHS Waiting Times

NHS waiting times for neurodevelopmental assessments vary significantly by area but are often extremely long:

• Autism assessment: 18 months to 4+ years in some areas
• ADHD assessment: 12 months to 3+ years
• Educational psychology: Often only available for children at school, with limited capacity

Right to Choose

Under the NHS Constitution, patients in England have the legal right to choose their healthcare provider for certain services, including ADHD and autism assessments. This means:

• You can ask your GP to refer you to a private provider that has an NHS contract
• The assessment is still NHS-funded (free at point of use)
• Waiting times may be significantly shorter than local NHS services

To use Right to Choose, the private provider must have an NHS contract and offer the same service somewhere in England. Your GP cannot refuse a Right to Choose referral if the criteria are met.

Private Assessment Routes

Advantages of Private Assessment

• Much shorter waiting times (often weeks rather than years)
• Choice of assessor and clinic
• Often more comprehensive reports
• May include conditions not assessed locally by NHS
• More family-friendly appointment scheduling

Disadvantages of Private Assessment

• Significant cost (often £500-£3000+ depending on assessment type)
• Variable quality between providers
• Some NHS services may not accept private diagnoses
• Ongoing treatment (medication) may still require NHS involvement

Will the NHS Accept a Private Diagnosis?

This is a common concern. The general position is:

• Quality matters: NHS services should accept private diagnoses if the assessment was conducted to the same standard as NHS assessments (following NICE guidelines)
• Reports must be comprehensive: A brief letter is not sufficient; a full report is needed
• Shared care for medication: GPs may be reluctant to prescribe medication without NHS specialist involvement
• Variable practice: Some areas are more accepting than others

Costs of Private Assessment

Typical costs (2024-2026 estimates):

• Autism assessment: £1,500 - £3,000
• ADHD assessment: £500 - £1,500
• Dyslexia assessment: £400 - £800
• Educational psychology assessment: £600 - £1,200
• Speech and language assessment: £300 - £600
• Occupational therapy assessment: £300 - £600

What to Expect During Assessment

Before the Assessment

• Complete questionnaires sent in advance
• Gather relevant documents (school reports, previous assessments, developmental history)
• Write notes about your concerns and observations
• Prepare your child (explain what will happen in age-appropriate terms)

During the Assessment

• Parent interview: Detailed discussion of developmental history, current concerns, and family background
• Direct assessment: The assessor works directly with your child using various activities and tests
• Observation: The assessor observes your child's behaviour, communication, and interaction
• Questions for you: Be prepared to answer detailed questions about your child's history

After the Assessment

• Feedback session: Discussion of findings (sometimes on the day, sometimes at a follow-up)
• Written report: Detailed report with diagnosis (if applicable) and recommendations
• Follow-up: Opportunities to ask questions and discuss next steps

Preparing Your Child

Help your child understand and feel comfortable:

• Explain simply: "We're going to meet someone who helps understand how children learn and think. They'll ask you some questions and you'll do some activities."
• Reassure: "There are no wrong answers. Just do your best."
• Avoid coaching: The assessor needs to see your child as they naturally are
• Practical preparation: Ensure they're well rested, fed, and as calm as possible
• Bring comfort items: If your child has special items that help them feel calm, bring them

Understanding the Report

Assessment reports can be overwhelming. Key sections include:

• Background and history: Summary of information provided
• Assessment methods: Tests and tools used
• Results: What the assessments showed, including scores and their meaning
• Clinical observations: What the assessor noticed during the assessment
• Formulation/diagnosis: The assessor's conclusions about what the findings mean
• Recommendations: Suggested support, interventions, and next steps

Using Assessment Results

Once you have an assessment report:

• Share with school: Provide the report to your child's SENCO and class teacher
• Request a meeting: Discuss how recommendations will be implemented
• EHCP applications: Use the report as evidence if applying for an Education, Health and Care Plan
• Access support: Explore interventions and therapies recommended in the report
• Apply for benefits: A diagnosis can support applications for DLA
• Inform home education: Use recommendations to shape your approach if home educating

When Assessments Don't Lead to Diagnosis

Sometimes assessment does not result in a diagnosis. This can feel frustrating, but:

• The assessment is still valuable: You will have information about your child's profile of strengths and needs
• Support should still be provided: Schools should support based on need, not just diagnosis
• Consider second opinions: If you believe the assessment missed something, another professional may see things differently
• Some conditions are missed: Autism in girls and those who 'mask' is frequently missed on first assessment

Finding Reputable Assessors

When choosing a private assessor:

• Check qualifications: Ensure they are appropriately qualified for the assessment type
• Look for experience: Specific experience with the condition you're investigating
• Ask about their approach: Do they follow NICE guidelines?
• Read reviews: What do other parents say?
• Check professional registration: HCPC for psychologists, relevant bodies for other professionals
• Ask about NHS acceptance: Will their diagnosis be accepted by your local NHS services?
