Misconceptions about dyslexia are held by professionals who assess children for the learning difficulty, according to a new study which calls for evidence-based standardized assessment procedures. The research, led by Durham University, found that almost half of dyslexia professionals in the study believed at least one unproven indicator for dyslexia, which could lead to children being misdiagnosed. In a survey of 275 dyslexia professionals, the most common myth—which is not backed up by solid evidence—was that people with dyslexia read letters in reverse order, believed by 61% of specialists.

Just over 30% of professionals also believed that letters jumping around is a key feature of dyslexia. However, there is currently no evidence to show that either of these are reliable indicators of dyslexia. The survey targeted a range of UK professionals involved in assessing students for dyslexia, such as dyslexia specialists, specialist assessors and educational psychologists.

They were asked about the assessments they used, how they make their decisions on diagnosis and what they believe to be indicators of dyslexia. Although over 75% of professionals used assessments which are recommended by the Specific Learning Difficulty (SpLD) Assessment Standards Committee (SASC), more than 82% of respondents also used additional measures. A further 71 different measures were listed by participants, indicating that there are many different tests used by professionals during the assessment.
