If you’ve been wondering whether dyslexia might be part of the picture — for your child, teenager or for yourself — Defining Dyslexia is here to help make things a little clearer.
I’m Mark, a specialist dyslexia teacher and assessor. I work with children from age 8, young people and adults, and the aim is always the same: to understand the whole person, not just produce a test score.
Defining Dyslexia offers diagnostic dyslexia assessments, both in person and remotely, alongside support with exam access arrangements, university and DSA evidence, study skills and workplace support. I can also explore traits associated with ADHD, dyspraxia and dyscalculia as part of the wider picture.
For families and schools, there is also SEN consultancy, APDR and EHCP support, training and SENCo support — plus a growing collection of completely free guides and practical resources.
In-person work covers Sheffield, South Yorkshire, Peterborough, Stamford, Rutland and South Lincolnshire, with remote support available UK-wide.
Not sure what you need? You don’t need to work that out before getting in touch. I’m always happy to have an initial conversation.

And one for later in the year: I run an annual free SpLD assessment competition. Details of the 2026 competition will be announced in November, so follow the page if you’d like to see the information when it’s released.
