If you are concerned that your child or teenager may have Attention Deficit Hyperactivity Disorder (ADHD) and are interested in having an assessment, Questa is able to help. We have a multi-disciplinary team, who are experts in assessing ADHD and other neurodevelopmental conditions and can offer valuable advice and guidance as well as signposting you to services that may be able to meet your on-going needs following the assessment.

Q. Will my child's school or college accept the outcome of an assessment conducted in the independent sector?

Many parents and carers may worry or may have heard that the assessment findings will not be accepted by their child's school or college because the assessment has not been conducted by clinicians working in the NHS. The issue is not whether your child has been assessed within the NHS or the private sector, but whether the assessment has been carried out by suitably trained, qualified and experienced clinicians and has followed NICE guidelines. All of the clinicians on our multi-disciplinary team (MDT) are fully trained and highly experienced in the assessment and diagnosis of neurodevelopmental conditions. The clinical leads for our autism pathway also work or have worked carrying out autism assessment in the NHS. Schools, colleges and the NHS will therefore be able to accept the findings as reliable and valid.

What is ADHD?

ADHD is usually first diagnosed in childhood and often lasts into adulthood. It cannot usually be diagnosed in children below the age of 6 years as the behaviour associated with ADHD is a normal part of early childhood.  It should only be assessed if the child or young person is not thriving or reaching their potential because of the difficulties caused by their symptoms.

It is typical for children and young people to have trouble concentrating and behaving. However, children with ADHD do not just grow out of this behaviour and it can cause problems for them. ADHD can cause difficulties at school, at home, or with friends.

A child or young person with ADHD may:
  • daydream a lot

  • forget or lose things a lot

  • be very disorganised

  • seem not to listen to or process what is being said to them

  • squirm or fidget

  • talk too much

  • make careless mistakes 

  • take unnecessary risks

  • act impulsively without apparent awareness of the consequences

  • have a hard time resisting temptation

  • have trouble taking turns

  • have difficulty getting along with others

  • leave tasks unfinished

  • find it difficult to know where to start with a task or assignment

  • have much more energy than would be expected and the need to move almost constantly

  • have difficulties getting to sleep and/or needing less sleep than same-age peers

Types of ADHD

There are three different types of ADHD, depending on which types of symptoms are strongest in the individual:

  • Predominantly Inattentive Presentation: difficulty organising or finishing tasks, paying attention to details, following instructions or conversations. The person is easily distracted or forgets details of daily routines.

  • Predominantly Hyperactive-Impulsive Presentation: fidgeting and talking a lot. It is hard to sit still for long (e.g., for a meal or while doing homework). Smaller children may run, jump or climb constantly. The individual feels restless or agitated and has trouble with impulsivity. Someone who is impulsive may interrupt others a lot, grab things from people, or speak at inappropriate times. It is hard for the person to wait their turn or listen to directions. A person with impulsiveness may have more accidents and injuries than others.

  • Combined Presentation: Symptoms of the above two types are equally present in the person.

Because symptoms can change over time, the presentation may change over time as well.

Does my Child Have ADHD?

You may be wondering if your child has ADHD because you or others have noticed that your child has behaviour often seen in children with ADHD. It is worth bearing in mind that a child without ADHD can sometimes present with ADHD, for example if they have learning difficulties, severe anxiety, experienced adverse childhood events or trauma, among other things. An assessment can help determine whether the behaviour is related to ADHD or if there is another possible cause.

What are the benefits of a diagnosis?

For many parents getting a timely and thorough assessment and diagnosis may be helpful because:

  • It provides a framework for understanding behaviour.

  • Getting the right diagnosis means accessing the right help or helping others understand their needs.

It means that school, colleges and universities can make reasonable adjustments for your child to make the environment more user-friendly.

A diagnosis can also help the young person make sense of their experiences.

It is up to you whether you decide to seek a diagnosis for your child; some people are happy to remain un-diagnosed. The only way to know for sure whether your child has ADHD is to have a formal diagnostic assessment.

The assessment process:

There are structured phases in the formal diagnostic process: 

1.     Initial Assessment appointment:

You will meet with one of our team to discuss your child’s development and behaviour. This lasts up to an hour and a half.

2.     Questionnaires:

If the initial assessment indicates that a diagnostic assessment would be helpful, it is important that we gather observer reported information from other sources who also know your child. A member of staff at your child’s school or college are very often the best source of information and with your permission, we will send questionnaires for them to complete and return.

At this point we discuss the assessment information gathered so far with you to decide whether a formal diagnostic assessment would be helpful.

3.     The diagnostic assessment:

Consists of a detailed diagnostic interview, which builds on the assessment information already gathered*.

4.     A feedback session

We will will go over the assessment with you and the outcome. A full report is produced, which includes detailed recommendations designed to meet the child/ young person’s needs, details of resources and other services that provide relevant support.

*Further observations may be needed if there is any doubt about the observer reports.

5.     Post-assessment:

If the assessment outcome was a diagnosis of ADHD, we can offer additional further post-assessment sessions to offer support, guidance and advice to address any on-going needs you may have. We can also offer consultation to schools, colleges and universities.

6.   Therapy and Support


We can also offer further therapeutic sessions to offer treatment for any behaviour or emotional concerns.

The assessment may highlight that additional assessment is needed or beneficial, for example a cognitive assessment to help clarify a learning profile and intellectual ability.  A behavioural analysis and expert advice in managing unhelpful behaviours in the family can be of great help too.
