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', i.e. 5-10 minutes. This would be booked for around one week before the assessment takes place.

DIAGNOSTIC ASSESSMENTS - £550 (£50 non-refundable deposit required within 7 days of the booking)

Dyslexia - adults and children age 7+

Dyspraxia - those aged 16+ only (see FAQs)

Identification of ADHD symptoms - those aged 16+ only (see FAQs)

A full diagnostic assessment usually takes around 2 hours followed by immediate verbal feedback so that I can explain my conclusion. Regardless of a formal diagnosis being made, a detailed but very practical report will be sent within 21 days which can be shared with schools, colleges, universities, employers, etc. If I suspect other underlying difficulties beyond my remit, it may also be appropriate to provide a referral letter and advice about how to pursue further specialist assessments through the NHS and privately. 


For schools and colleges:

I regularly work with SENCos to assess students in year 9 and above for exam access arrangements, whether this is part of a privately-commissioned full diagnostic assessment where the school/college would like to use the results from my report or when I'm asked to come in to assess cohorts of students, such as year 10s. Form 8s are completed with the results of age-appropriate standardised tests and returned within 48 hours. SENCos, please contact me regarding my rate. I can provide a copy of my current SpLD APC and enhanced DBS certificates. Payment is asked for within 30 days of the invoice date.

For students and families:

Exam access arrangements refer to the type of help which students may benefit from in exams, such as extra time. Such arrangements must reflect students' 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, you must 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 who to approach whilst following the regulations set by JCQ (Joint Council of Qualifications). However, I'm always happy to forge new links with schools/colleges if they'd like to work with me and use the scores from my reports.

Professional exams:

I often see candidates taking professional exams, such as the ICAEW, 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 purely for exam access arrangements) and whether additional paperwork needs to be completed for which there may be an additional cost.


When home / school / workplace visits can be offered, there is an additional cost of £25 if this is within Surrey, Sussex and Kent.                               

Please contact Sarah regarding fees for:

  • assessments that need to be carried out over at least 2 sessions
  • assessments conducted beyond Surrey, Sussex and Kent including abroad (but please note I can assess online)
  • assessments for exam access arrangements


For individuals, I ask for a £50 non-refundable deposit within 7 days of the booking. The balance is kindly requested before or on the day of the assessment. Payment can be via:

  • cash
  • cheque
  • BACS
  • debit / credit card (via emailed payment link)


Education providers and employers are asked to settle payment within 30 days of the invoice date via the above payment methods.
