There are many reasons to have a Diagnostic Assessment. You may wish to apply for a Disabled Students' Allowance, Exam Access Arrangements or Reasonable Adjustments in the workplace. You may just want to have a greater understanding of why you, your child or employee are experiencing difficulties and how these can best be supported.

We can arrange an assessment for you with an experienced assessor and are on hand to answer any questions you may have.

We aim to arrange your assessment within 7 days of receiving your booking and to find an assessor close to you. However, we have more availability in some parts of the UK than others, so we may ask whether you are willing to travel, especially if it is an urgent booking.

Can I be assessed if English isn’t my first language?

To be assessed you will need to have lived in an English-speaking country and to have been regularly speaking English for a minimum of seven years. This is because the tests used are heavily influenced by an English-speaking culture. In addition, you need to be able to read, write and spell in English. If an assessment is carried out before then the assessor can’t make a definitive diagnosis which would mean a re-test may be needed at a later date.

How much does it cost?

The cost of an assessment is £540 (£450 + VAT) with a specialist teacher. Our specialist teacher/assessors have a current Assessing Practising Certificate (APC).

An assessment with an educational psychologist is £720 (£600 + VAT). All associate psychologists are registered with the Health and Care Professional Council (HCPC).
