Diagnostic Assessments

If you are looking for a full diagnosis of dyslexia and dyscalculia for a child or adult, a Diagnostic Assessment can help.


Who benefits from a diagnostic assessment?

  • Anyone aged 7 or above for whom screening is not adequate proof of learning difficulties or neurodiversity.
  • An individual due to sit examinations who feels that they may qualify for additional support.
  • A university student looking to apply for Disabled Students Allowance (DSA) and obtain support at university.
  • An employer wishing to understand how to support a staff member, and subsequently apply for Access to Work. 


You will receive:

  • A diagnosis which complies with the Equality Act (2010). The assessment can also provide an educational diagnosis of  dyscalculia.
  • A completely independent, in-depth assessment, including testing of phonological awareness and cognitive ability.
  • A clear assessment report detailing strengths and weaknesses, and a framework of recommendations for school, home or the workplace.


The diagnostic report will contain:

  • A diagnosis where possible.
  • An analysis of factors which may be barriers to learning.
  • Results of the personalised tests performed on the day, what they mean and what you can do next.
  • Recommended methods of support.


What will happen on the day?

You will meet with an assessor at the Indigo Dyslexia Centre. They will initially have a short discussion with you about the reasons for you / or your child’s assessment and the background history.

Following this, the assessment will take place in one of our private assessment rooms, where we keep the testing process as relaxed and as informal as possible.

Once the assessment is complete, the assessor will discuss their initial findings with you. They are normally able to indicate their potential conclusions on the day.


What happens after the assessment day?

The specialist teacher will write a thorough report that includes the test results as well as detailed and comprehensive recommendations based on the data. 

For a child, recommendations typically cover school as well as home support, and for an adult, we can cover employment, college and university support. 

You will normally receive your report within two weeks of the assessment day. We will send you two paper copies in the post as well as an electronic copy by e-mail. 


How long does an assessment take?

Assessments vary in length due to the complexity of any needs and the purpose of the assessment, but approximately two hours is common.


How much does it cost?

£296.00 (inc. VAT)


Locations available:


Schools, Clusters, Colleges and Universities

You may wish to pay for diagnostic assessment for your students. If this is the case, you have several options:

We can perform diagnostic assessments on students at our centres if they arrive with a letter or email from the institution containing invoicing information and the service that is required. 

A staff member could bring a group of students to the centre for testing. The conditions above would apply along with written parental consent if the students are under 16.

Alternatively, an on-site visit can be arranged. This can be carried out if numbers are sufficient but it will need to be arranged in advance.

Two copies of the diagnostic assessment report are provided following the assessment.
