Dyslexia Assessments for Adults and Children

Balloons and clouds rising from book inspirational


At Helen Arkell, we offer a range of assessments for adults and children.

At Helen Arkell we have our own team of highly trained Specialist Assessors (HASAs) who are professionally qualified to assess, report, and diagnose dyslexia.  They are also able to advise on all aspects of dyslexia and literacy/numeracy. As a general rule while many assessments are carried out by HASAs,  we also work with affiliated Educational Psychologists on a regular basis.

Where do assessments take place?

The majority of our assessments are carried out at our Helen Arkell Centre, Frensham, near Farnham, Surrey GU10 3BL, UK.

STOP PRESS! We can now also offer some assessments at our new London Hub, at Bell House in Dulwich. Assessments are generally available on alternate Fridays. Bell House has easy access from central London with three nearby stations - West Dulwich, North Dulwich and Herne Hill. The postcode is SE21 7BG. We are pleased to work in collaboration with Bell House, which is a charity in its own right.

All bookings for assessments at our Frensham Centre and our London Hub at Bell House are handled by the same admin team. Please make us aware of your preferred venue when contacting us.

The first step to arranging an assessment is to complete one of our comprehensive questionnaires to give us background information.  Once your questionnaire is received, one of our senior professional staff will read it and recommend which assessment is most appropriate.

Next, you will be contacted by our administrative staff who will offer you a selection of dates and times to book an assessment, should you wish to proceed.  If you need more time to consider your way forward, then there is no obligation to commit to an assessment at this point. You may wish to come in  and talk to one of our professionals. If so, do make an appointment for either a Consultation for Adults or a Consultation for Parents.

Once you are ready to book an assessment date, a deposit is needed to secure the booking. 

All assessments arranged through the Centre allow time before and after the assessment for discussion.

“I just wanted to thank you and your colleagues at Helen Arkell for your time and support through the assessment process yesterday. It was an extremely positive experience and the friendliness and courtesy of all the staff really helped.  The assessment was extremely thorough, professionally conducted and I look forward to receiving my report”  JY

“I really appreciate your support in getting H assessed so quickly and the kind, caring and supportive environment provided by the team at the Helen Arkell that enabled H’s assessment to be as stress free as possible.” CC

Reports written by Helen Arkell Specialist Assessors are sent within 3 weeks of the assessment. When the assessment is carried out by an Educational Psychologist (EP), s/he will advise the delivery date for the report.

“..Mrs T. said thank you for what was ‘one heck of a report’ and she was ‘bowled over’.  She took it into school and the SENCO/tutor in school said she had ‘never seen one as thorough’ .”  MT

On some occasions it is not possible to offer a clear-cut diagnosis of dyslexia.  In such circumstances, a comprehensive description of the profile, including strengths and weaknesses will be given.  If necessary, other professionals, such as a speech and language therapist or occupational therapist may be recommended and contact details will be provided.
