Cognitive & IQ testing for adults & children

A cognitive assessment does something a school report or a teacher's observation can't: it gives you an objective, detailed map of how someone's mind actually works. Not just whether they're "smart",  but how they think, where they're strong, where things are harder, and why. That information changes everything from how a child is taught to whether a student gets extra time in exams.

What is cognitive or IQ testing?

Cognitive or IQ testing measures a range of mental abilities, including reasoning, memory, processing speed, language, attention and executive functioning - using standardised, validated tools. Rather than producing a single number, a well-conducted cognitive assessment produces a profile: a map of relative strengths and weaknesses across different areas of thinking and learning.

This profile is often far more useful than a single IQ score. It can explain why someone who is clearly intelligent still struggles with certain tasks - and point toward the most effective strategies and supports.

Who is cognitive and IQ testing for?

For adults

  • You need documentation for university exam accommodations or disability support
  • You are seeking workplace adjustments and require objective evidence
  • You've noticed changes in your memory, concentration or thinking and want to understand what's happening
  • You've experienced a head injury, illness or other medical event affecting cognition
  • You are involved in legal proceedings requiring a cognitive assessment

For children

  • A child is struggling academically despite apparent ability
  • There are concerns about intellectual disability or developmental delay
  • Giftedness is suspected and appropriate educational placement is being considered
  • You are considering an application to a selective school or gifted programme and want an objective cognitive profile to inform that decisionAssessment is required for school accommodations or learning support plans
  • A learning disability such as dyslexia is suspected and a full cognitive profile is needed to understand it properly

What does the assessment involve?

Dr Gill Walker uses the Wechsler family of assessments - the gold standard in cognitive testing - selecting the appropriate battery based on age and the questions being asked:

  • WPPSI — for preschool and early primary-age children
  • WISC — for school-age children and adolescents
  • WAIS — for adults
  • WIAT — academic achievement in reading, writing and mathematics
  • WMS — memory and learning
  • D-KEFS / NEPSY — executive function and developmental neuropsychology where indicated

The assessment measures abilities including general intelligence, verbal comprehension, visual-spatial reasoning, fluid reasoning, working memory, processing speed, academic attainment, and memory and learning.

Cognitive testing also forms the foundation of school readiness, giftedness and exam accommodation assessments - the difference lies in the purpose of the assessment and how the report is used. If you're looking for one of those specifically, see the school readiness, giftedness and exam accommodations page.

What will I receive at the end

You'll receive a comprehensive written report that includes:

  • Full cognitive profile across all assessed domains
  • Interpretation of results in plain language - what they mean for school, work and daily life
  • Identification of strengths to build on as well as areas where support is beneficial
  • Specific, practical recommendations for educators, employers or treating clinicians
  • Documentation suitable for use in school support plans, university disability services, or legal and medico-legal contexts

How the process works

Assessment takes place across several appointments and includes a consultation, direct assessment sessions and a feedback meeting. A written report is delivered within six weeks. See our full step by step guide here
