Sheffield & South Yorkshire
Dyslexia Assessments in Sheffield
Sheffield is one of the largest cities in England, with a diverse and growing SEND community across the city and the wider South Yorkshire area. Whether you are a parent whose child has been struggling at school for some time, an adult who has long suspected dyslexia might explain your experiences, or a student at the University of Sheffield or Sheffield Hallam preparing a DSA application, a full diagnostic assessment gives you something clear and concrete to work with.
Sheffield is Defining Dyslexia's northern base, and it is the area Mark travels across most often, the city itself, out to Stocksbridge and the north-west edge, and down towards the Derbyshire boundary. Many people search for a "dyslexia test" in Sheffield when what they actually need is a full diagnostic assessment, and that is what is provided here.

Face-to-face that comes to you
Assessment shouldn't add another journey to the week. Across Sheffield, Mark travels to you, and remote assessment is available where that suits better.
- At home
- At school

- Remotely
Availability depends on location and on the room being quiet and suitable, so it is worth asking early. There is no assessment centre to visit.

Assessment in Sheffield: the local picture
Sheffield City Council publishes a SEND Local Offer covering support across the city, and Sheffield SENDIAS provides free, impartial advice to families. Both are genuinely useful, and worth reading before you spend anything.
What neither can provide is a formal diagnostic assessment. Schools can identify concerns, put support in place and apply for exam access arrangements, but a school cannot diagnose dyslexia. There is no routine NHS route either. For most Sheffield families, a private specialist assessment is the realistic way to get a formal answer.
Sheffield is also home to two large universities (the University of Sheffield and Sheffield Hallam) with substantial student populations. Students who need diagnostic evidence for a Disabled Students' Allowance application need a SASC-compliant report from a qualified assessor, which is what Defining Dyslexia provides.
Where the assessment takes place
Face-to-face assessments across Sheffield can take place in your own home, at your child's school where the school agrees, or at a suitable local venue arranged for the session.
Defining Dyslexia does not run an assessment centre or clinic in Sheffield. That is deliberate, travelling to the family is usually kinder for a child than sitting a long assessment in an unfamiliar building. Where a room has to be hired, a small additional venue fee may apply, and it is always discussed and agreed with you before anything is booked.
The assessment itself
What a full diagnostic assessment involves
An assessment usually takes around two to three hours, with breaks, and can be split across two shorter sessions where that would suit better. It begins with a conversation about background, education and what has prompted the enquiry, followed by a series of standardised tasks.
Those tasks look at underlying cognitive processing, verbal and non-verbal reasoning, phonological processing, working memory and processing speed, alongside attainment in reading, spelling and writing. It is the relationship between those areas, not any single score, that determines whether the profile meets the criteria for dyslexia.
Every assessment is carried out to the standards set by SASC, and the written report follows within an agreed timescale. It sets out the findings in plain English, explains what they mean day to day, and makes practical recommendations for school, college, university, work or home.
What you receive
- A full diagnostic report written to SASC standards
- A clear explanation of strengths as well as difficulties
- A formal diagnostic outcome where the criteria are met
- Practical recommendations for education, work or study
- A follow-up conversation to talk the findings through

How this fits with an assessment
Every local authority in England must publish a Local Offer setting out the SEND provision available in its area. Defining Dyslexia is an independent specialist assessment service and is not part of, commissioned by or endorsed by any local authority. These links are provided because they are genuinely useful sources of wider information.
A diagnostic assessment is one form of evidence. The Local Offer is where you find what your council already provides, and what to ask for locally.

Sheffield: frequently asked questions
01Can the assessment take place at my home in Sheffield?
Yes. Face-to-face assessments can be carried out at your home, at your child's school where the school agrees, or at a suitable local venue across Sheffield and South Yorkshire. Where a venue needs to be hired, the arrangement and any small additional fee are agreed with you in advance.
02Will Sheffield schools and colleges accept the report?
Reports are written to SASC standards, which is the evidence base schools, colleges, exam boards, universities and local authorities across the UK look for. Each organisation still applies its own criteria and makes its own decisions about support, so no assessor can guarantee a particular outcome. What the report does is give the school or college the specialist diagnostic evidence they need to act.
03Do you work with University of Sheffield or Sheffield Hallam students?
Yes. Adults and students aged 16 and over are assessed regularly. A SASC-compliant diagnostic report is the type of evidence normally required for a DSA application and for access arrangements in higher education. The funding decision itself sits with the DSA assessor and Student Finance, not with Defining Dyslexia.
04How quickly can I get an appointment in Sheffield?
Waiting times are kept under two months, and are often considerably shorter. Remote appointments can frequently be arranged faster than face-to-face ones. Get in touch for current availability, a free 15-minute telephone call is the quickest way to find out.
05My child's school in Sheffield says it cannot diagnose dyslexia. What should I do?
This is very common and the school is correct. Schools identify concerns and put support in place, but a formal diagnostic assessment requires a qualified specialist assessor. A full assessment gives you and the school a clear picture of your child's profile, with practical recommendations that can be used straight away.
06How long does the assessment take?
Most assessments take around two to three hours. Split sessions are available where they would help, particularly for younger children or anyone who finds a long session difficult.

About your assessor
You are booking with Mark
Every assessment in Sheffield is carried out by Mark personally. He is a PATOSS-registered specialist assessor with fifteen years of experience working with children, young people and adults, and holds a current Assessment Practising Certificate (APC), working to the standards set by SASC.
He is a qualified teacher and former SENCo, which shapes how the reports are written, for the people who have to use them. You will not be allocated to an unknown assessor by a national company: you speak to Mark at enquiry, he carries out the assessment, and he writes the report.
