Contribution of lower order skills to the written composition of college students with and without dyslexia.

There has been a growth in students with dyslexia attending university. These students commonly rate writing as one of their greatest problem areas. Our research set out to describe the effects of dyslexia on the writing skills of students compared to age-matched peers and a spelling-skill-matched group. Generally, the texts of the students with dyslexia were poorer than age controls but not poorer than the spelling-skill controls. However, there were no major differences in "higher order" skills such as ideas and organization with the chronological age controls, only in "lower order" transcription skills such as spelling and handwriting fluency. The students with dyslexia made more spelling errors in their essays than one would predict given their dictated spelling skills.
