Services and fees


I understand that assessments can feel really daunting, especially if they're being conducted by someone unfamiliar. Therefore, once an assessment is booked, you're welcome to book a Zoom session with me to say a quick 'hello'. This would be booked for around one week before the assessment takes place. Children have told me that these sessions have been useful to ask me questions, tell me all about themselves or whatever comes to their minds! When they then see me, it doesn't feel as scary. 




Diagnostic dyslexia assessments for adults and children age 7+

Diagnostic dyspraxia assessments for those aged 16+ only

Identification of ADHD symptoms for those aged 16+ only

A full assessment with immediate verbal feedback usually takes between 2 and 3 hours. In most cases, the assessment will result in a formal diagnosis based on background information, attainment in tests and observations. Whilst dyslexia is commonly seen, some people may instead have a specific learning difficulty with features of working memory, processing speed, etc. that impact on literacy skills. However, even if there is insufficient evidence to support a clear cut case for a specific learning difficulty, a detailed report is sent which outlines strengths and areas of development along with practical strategies. Where relevant, I may signpost clients to other professionals such as occupational therapists, a private consultant paediatrician, behavioural optometrists, speech and language therapists, medical-based ADHD assessment centres, etc.

At the time of booking, I send a questionnaire to the family / adult client and ask that this is returned to me before the assessment date. It may also be appropriate to send questionnaires for the school or employer, and clients are asked to forward on these.

The Disabled Students' Allowance (DSA) can provide software, equipment and individual study skills tuition to students who are studying at Higher Education level. The student's course must be equivalent to at least one year's full time study, e.g first degrees, foundation degrees, HNDs, PGCEs, Certificates of Higher Education, etc. In order to apply for the DSA, there must be a diagnosis in place and therefore clients need to provide a full diagnostic report written by an educational psychologist or a specialist assessor with an Assessment Practising Certificate. This is different to the short assessments that schools and colleges do for GCSE and A' level exam access arrangements.                                



Exam access arrangements (EAAs) refer to the type of help which students benefit from in exams. The better known EAAs are extra time, reader and word processor but there are many more types of arrangement which can help. Such arrangements must reflect the student's 'normal way of working' and therefore schools and colleges take the lead in determining if any help is needed. If you think your chld needs help in exams, it is important that you talk to the SENCo in the first instance.

In the vast majority of cases for GCSE and A' level exams, short assessments are handled in-house from year 9 onwards. If this is not possible, the school is likely to have an established working relationship with external educational psychologists and specialist teacher assessors, and can advise families on who to approach whilst following the regulations set by JCQ (Joint Council of Qualifications). However, if schools/colleges would like to add me to their lists of approved assessors, including for common entrance and GCSEs/A' levels, please do get in touch.

Some schools/colleges may be geographically remote (including those abroad) and be unable to find an assessor. Where face-to-face is not possible, short EAA assessments can be conducted remotely. However, this is a complex process and will involve working very closely with the SENCo both before and on the assessment date. This is to ensure that validity of the results is not compromised and safeguarding issues do not arise. 

I often see candidates taking professional exams, such as the Chartered Financial Analyst (CFA) accountancy qualification, UK legal qualifications, US state bar exams, etc. Clients are advised to check with the professional body about exactly what evidence is needed (i.e. a full diagnostic assessment or a short EAA assessment) and whether additional paperwork needs to be completed.



'Meet Sarah via Zoom' chats before assessments are free.

I charge £475 for full diagnostic assessments for children and adults conducted in the assessor's home.

There is an additional cost of £25 for assessments carried out in clients' homes, schools or workplaces in Surrey, Sussex and Kent.                                .

Please contact Sarah regarding fees for:

  • assessments that need to be carried out over at least 2 sessions
  • assessments for exam access arrangements 
  • additional paperwork that needs to be completed, such as legal documents
  • assessments conducted in other areas or abroad (please see FAQs)



For full diagnostic assessments, I ask for payment on the day of the appointment. This can be done by cash, cheque or BACS and I will issue you with a receipt if you would like one. Reports are sent within 21 days unless agreed before the assessment.



Yes, that is fine. Having already agreed payment prior to the assessment, I will invoice the company or educational institution after the assessment and ask that payment is made within 30 days of the invoice date.
