Private Assessments for Children: What You Need to Know

Why Parents Choose Private Assessments

I talk to parents every week who have reached the same point. Their child is struggling, school has raised concerns or perhaps dismissed them, and the NHS waiting list stretches months or even years into the future. The decision to go private is rarely taken lightly. It is almost always driven by a combination of urgency and frustration with a system that simply cannot move fast enough.

The most common reason families pursue a private assessment is speed. NHS waiting times for children's neurodevelopmental assessments vary enormously across the UK, but waits of twelve to twenty-four months are not unusual for autism or ADHD assessments. For speech and language or educational psychology, the picture is sometimes better, but not always. When your child is falling behind in school, losing confidence, or becoming increasingly distressed, waiting that long feels impossible.

Another reason is access to a specific type of assessment that may not be readily available through local NHS services. Some families need an educational psychology assessment to support an EHCP application, or a detailed cognitive profile to inform exam access arrangements. These assessments may not be offered routinely through the NHS in every area, and a private route can fill that gap.

There are also parents who have been through the NHS pathway and come away feeling that the assessment was too brief, too narrow, or did not capture their child's full picture. Private assessments often allow more time, more flexibility, and a more individualised approach. This is not a criticism of NHS professionals, who are working under enormous pressure, but a reflection of the reality that caseloads and time constraints affect what can be achieved in a single appointment.

Some families come to private assessment after being turned down for NHS referral altogether. A GP or school may have decided that the child does not meet the threshold for referral, but the parents remain concerned. In these cases, a private assessment can provide clarity and, if a need is identified, open doors to support that might otherwise have remained closed.

Whatever your reason, it is worth understanding what private assessment involves, what it costs, and how to make sure the outcome is useful. The rest of this guide walks you through exactly that.

Types of Private Assessment Available

Private assessments for children cover a broad range of needs, and the type you choose will depend on what concerns you have about your child. Understanding what is available can help you make a more informed decision about where to start.

Educational psychology assessments are among the most commonly sought. An educational psychologist will assess your child's cognitive abilities, learning strengths and weaknesses, and the way they process information. These assessments are particularly valuable if you are concerned about dyslexia, dyscalculia, or general learning difficulties. They are also used to support requests for EHCPs and exam access arrangements. A good educational psychology report does more than produce scores. It explains what those scores mean for your child's day-to-day learning and provides specific, actionable recommendations for school and home.

Autism assessments are another area where private practice has grown significantly. A private autism assessment is typically carried out by a clinical psychologist, psychiatrist, or paediatrician, and follows the same diagnostic criteria and assessment tools used by the NHS. The ADOS-2 (Autism Diagnostic Observation Schedule) and the ADI-R (Autism Diagnostic Interview) are commonly used, alongside clinical observation and developmental history. Some private clinics offer multidisciplinary assessments with input from speech and language therapists as well.

ADHD assessments are usually carried out by a psychiatrist or paediatrician. The assessment includes a detailed developmental history, behavioural questionnaires completed by parents and teachers, and clinical observation. Some assessors use computerised attention tests as part of the process. If your child is subsequently prescribed medication, you will need a shared care agreement with your GP for ongoing management.

Speech and language assessments look at how your child understands and uses language, including vocabulary, sentence structure, social communication, and sometimes feeding and swallowing. Occupational therapy assessments focus on fine motor skills, sensory processing, coordination, and daily living skills. Both are available privately and can be completed relatively quickly compared to NHS routes.

If you are not sure which type of assessment your child needs, a good starting point is to speak with a professional who can help you think through the concerns and point you in the right direction. You can browse specialists on ChildWize by area of expertise, which makes it easier to find someone with the right background for your child's particular needs.

What a Private Assessment Involves

The assessment process will vary depending on the type of assessment and the professional carrying it out, but there is a general shape that most assessments follow.

Before the assessment itself, you will usually be asked to complete questionnaires and provide background information about your child. This might include developmental history, medical history, school reports, and any previous assessments or professional letters. Take your time with these forms. The more detail you provide, the better the assessor can understand your child's situation before the session even begins.

The assessment session itself can last anywhere from one to four hours, depending on the complexity. For younger children, much of the work is done through play, puzzles, picture cards, and activities that feel like games rather than tests. For older children and teenagers, there will be more structured tasks, conversations, and sometimes standardised tests. Throughout, the assessor is observing how your child approaches tasks, responds to challenges, communicates, and interacts.

Some assessments require input from school as well. Teacher questionnaires are a standard part of ADHD assessments, and many educational psychology assessments include a classroom observation or at least written feedback from the class teacher or SENCO. The assessor may contact the school directly or ask you to pass on the forms.

Most private assessments today can be carried out online, and many families find this works well. Children are often more relaxed at home, and the technology used for online assessments has improved significantly. Standardised tools have been adapted for remote delivery, and research supports the validity of well-conducted online assessments. That said, some assessments, particularly those involving physical tasks like fine motor assessments in occupational therapy, may still require a face-to-face session.

After the assessment, the professional will analyse the results and prepare a written report. This typically takes two to four weeks. A good report should include a clear description of what was assessed, the methods used, the findings, and detailed recommendations for support at home and school. If a diagnosis is made, the report should explain the basis for that diagnosis and what it means in practical terms.

Many assessors will offer a feedback session to talk you through the results. This is invaluable. It gives you the chance to ask questions, understand the nuances, and start thinking about next steps. If a feedback session is not included as standard, it is worth asking whether one can be arranged.

How Much Private Assessments Cost

Cost is one of the biggest factors in deciding whether to go private, and it is important to have realistic expectations about what you are likely to pay. Prices vary depending on the type of assessment, the professional's experience, and where in the UK you are based, though online assessments have levelled this out somewhat.

As a rough guide, an educational psychology assessment typically costs between five hundred and twelve hundred pounds. This usually includes the assessment session, a detailed written report, and a feedback discussion. Some educational psychologists offer shorter, more focused assessments at a lower price point, while comprehensive assessments involving classroom observation and multiple sessions will be at the higher end.

Autism assessments tend to be more expensive because they are more complex and time-consuming. You can expect to pay between fifteen hundred and three thousand pounds for a thorough autism assessment. Multidisciplinary assessments involving more than one professional will cost more, but they also provide a more comprehensive picture.

ADHD assessments generally fall between eight hundred and two thousand pounds. The variation depends on whether the assessment includes computerised testing, how many sessions are involved, and whether follow-up support such as medication titration is included in the price.

Speech and language assessments and occupational therapy assessments are usually less expensive, typically ranging from three hundred to eight hundred pounds depending on the depth and complexity of the assessment.

These are significant amounts of money, and I understand that for many families they represent a real financial stretch. Some families save over time, others use savings or gifts from grandparents, and some spread the cost across credit. A few private health insurance policies cover children's assessments, so it is worth checking your policy if you have one.

The investment is in the report and the recommendations that come with it. A thorough private assessment report can support an EHCP application, inform exam access arrangements, guide school support planning, and give you a clear understanding of your child's needs. When you weigh that against months or years of waiting without answers, many families feel the cost is justified.

One thing I would encourage is to be cautious about assessments that seem unusually cheap. A very low price may indicate a less thorough process, shorter sessions, or a less experienced professional. Ask what the assessment includes before you book, and check the assessor's qualifications and registration.

Making Sure Your Private Assessment Counts

A private assessment is only as useful as the recognition it receives from the people who need to act on it. Schools, local authorities, and other professionals should accept a private assessment carried out by a suitably qualified and registered professional, but in practice, you sometimes need to be proactive about making sure this happens.

The most important thing is to ensure your assessor is properly qualified and registered. Psychologists should be registered with the Health and Care Professions Council (HCPC). Doctors should be on the General Medical Council (GMC) register. Speech and language therapists and occupational therapists should also be HCPC registered. You can check registration on the relevant body's website. If an assessor is not registered with the appropriate body, their report may not be accepted.

The SEND Code of Practice 2015 is clear that assessment should be needs-led, not diagnosis-led. This means that a school or local authority cannot simply dismiss a private report because it was not produced by an NHS professional. If your child has been assessed by a qualified professional and the report identifies needs and recommends support, the school has a duty to consider that information.

In the context of EHCP applications, private assessment reports are valid evidence. When you submit a request for an EHC needs assessment, include the private report alongside any school-based evidence. Local authorities are required to consider all relevant evidence, regardless of its source. Our guide on how to get an EHCP goes into more detail about this process.

For exam access arrangements, the JCQ has specific requirements about assessor qualifications. Educational psychologists and specialist assessors with an Approved Practising Certificate can carry out the assessments needed for access arrangements. Check that your assessor meets these criteria if exam access is a priority. Our guide on exam access arrangements covers the JCQ requirements in detail.

If you encounter resistance from a school or local authority, ask them to explain their position in writing and cite the legal or regulatory basis for their refusal. Most will not be able to do so, because there is no legal basis for rejecting a valid private assessment. If the issue persists, organisations like IPSEA and SOS!SEN can advise on your rights.

Finally, make sure the report itself is thorough and specific. A good private assessment report should not just say your child has a particular condition or difficulty. It should explain the impact on learning and daily life, and provide concrete recommendations that teachers and support staff can implement. The more detailed and practical the report, the harder it is for anyone to dismiss it.

What Happens After the Assessment

Receiving the assessment report is not the end of the process. It is really the beginning of a new phase where you use the findings to get your child the right support.

The first step is to share the report with your child's school. Arrange a meeting with the SENCO and, ideally, the class teacher. Walk them through the key findings and the recommendations. Do not just hand over the document and hope it gets read. Teachers are busy, and a conversation about what the report means in practice is far more effective than a forty-page document sitting in a filing cabinet.

If the report recommends specific interventions, such as speech and language therapy, occupational therapy, or a particular teaching approach, discuss with the school how these can be put in place. Some interventions can be delivered by the school. Others may require external professionals. If the school does not have the resources to implement the recommendations, this is useful evidence that your child's needs may exceed what can be provided at SEN Support level, which may strengthen a case for an EHCP.

You may also want to share the report with your child's GP, particularly if the assessment identified a condition like ADHD that may benefit from medical management. Your GP can use the private assessment as a basis for referral to local NHS services, or for entering into a shared care arrangement for medication if appropriate.

Some families choose to pursue further assessment or intervention after the initial report. For example, if an educational psychology assessment identifies possible autistic traits, the family might then pursue a specific autism assessment. Or if a speech and language assessment highlights areas that need therapy, the next step is to arrange regular therapy sessions. You can find specialists for ongoing support on ChildWize, including therapists who offer regular sessions rather than one-off assessments.

Keep a copy of the report somewhere safe and accessible. You may need it again for school transitions, EHCP reviews, exam access arrangement applications, or future assessments. It becomes part of your child's ongoing evidence base, and having it readily available saves time and effort later.

Above all, remember that the purpose of the assessment is to help your child. The report gives you knowledge, and knowledge is power. You now have a clearer picture of your child's strengths and needs, and that puts you in a stronger position to advocate for them.

Finding the Right Assessor Through ChildWize

Choosing the right professional to assess your child is one of the most important decisions in this process. You want someone who is properly qualified, experienced with children, and able to produce a report that will be taken seriously by schools and local authorities.

ChildWize connects families with qualified assessors across a range of specialisms. Every specialist on our platform is registered with the appropriate professional body, and we verify qualifications before anyone is listed. You can browse our specialists by area of expertise, whether that is educational psychology, clinical psychology, speech and language therapy, occupational therapy, or developmental paediatrics.

One of the things families tell us they value most is being able to read reviews from other parents before choosing a specialist. When you are paying for a private assessment, you want to feel confident that you are choosing someone who is thorough, approachable, and good with children. Parent reviews help you make that judgment in a way that a list of qualifications alone cannot.

All assessments booked through ChildWize take place online, which means you are not limited to professionals in your local area. If the best educational psychologist for your child's particular needs is based two hundred miles away, you can still access them. This is particularly helpful for families in areas where specialist services are limited.

Booking is straightforward. You choose a specialist, select a time that works for your family, and the session takes place through our secure video platform. There are no referrals needed and no waiting lists in the NHS sense. Most families can book an assessment within a few weeks.

If you are unsure what type of assessment your child needs, our specialists can help with that too. Many families start with an initial consultation to discuss their concerns and work out the best next step. This can save you time and money by making sure you are pursuing the right type of assessment from the outset.

The reports produced by ChildWize specialists are designed to be clear, detailed, and practical. They are written with the understanding that they may be used to support EHCP applications, exam access arrangements, school support plans, and conversations with local authorities. Our assessors know what these reports need to contain to be taken seriously, and they write accordingly.
