Dyslexia is a controversial concept. In UK universities, the number of students possessing a dyslexia diagnosis continues to increase. Legislation requires that teaching staff adapt their pedagogic practices to effectively include students so diagnosed. These actions depend on lecturers having up-to-date knowledge of what the dyslexia label currently means. This study explored the nature and extent of UK lecturers' awareness of, and attitudes towards, dyslexia and dyslexic students. One hundred and sixty-four lecturers working within a range of disciplines in 12 UK universities were surveyed via an online questionnaire. The findings revealed a high degree of positivity towards dyslexic students and academic accommodations like reasonable adjustments. The positivity, though, was typically underpinned by inadequate awareness of current dyslexia research knowledge. Notable consequences included confusion and feelings of inadequacy around how best to meet the needs of dyslexic students, a resultant reliance on generic reasonable adjustments, and disinclination to fully engage with related equity issues. The study's quantitative estimate of the extent of these findings, together with its analysis of cross and inter-institutional differences, adds a new dimension to existing knowledge in the field. It has serious implications for the overall quality and equality of teaching and learning in higher education.
