Uneven Cognitive Profiles and Assessment Validity

Uneven Cognitive Profiles and Assessment Validity

Many people show marked differences between how they reason and understand on the one hand, and how quickly, fluently, or consistently they can demonstrate that understanding on the other. These uneven cognitive profiles are common in neurodivergent conditions such as dyslexia and ADHD, and are frequently present in autism. Where assessment systems assume that cognitive abilities are broadly even, this unevenness is easily misinterpreted as lack of capability, inconsistency, or poor performance. In practice, decisions are often shaped by the most constrained aspect of functioning — such as speed, working memory, or mode of expression — rather than by underlying reasoning or professional competence. This leads to assessment outcomes that do not reliably reflect actual ability, and creates predictable risks of misjudgement across education, employment, and decision-making settings.

This resource explains why such misassessment occurs, how to recognise when assessment processes are measuring constraints rather than capability, and how appropriate adjustments restore the validity of evaluation. It is intended to support earlier, more accurate understanding of ability — before misunderstandings escalate into exclusion, disciplinary action, or formal dispute.
