If you think you or your child may have dyslexia, you can take a screener test to estimate the probability.
Not all screeners online are research-based and may have questionable validity. So we are providing you with the links to 3 scientifically-based online screeners for dyslexia developed by a team of experts in Colorado, including Dr. Bruce Pennington, who formed part of the advisory board at ForDyslexia.
The screeners have been published on the IDA website for free use. They are short questionnaires that will let you know if you are at risk of having a reading disability and should, therefore, seek a formal evaluation.
Here are links to each screener according to age.
The Colorado Learning Disabilities Questionnaire – Reading Subscale (CLDQ-R) is a screening tool designed to measure risk of reading disability (i.e. dyslexia) in school-age children (Willcutt, Boada, Riddle, Chhabildas, DeFries & Pennington, 2011).
Pre-school age children
The Adult Reading History Questionnaire (ARHQ) is a screening tool designed to measure risk of reading disability (i.e. dyslexia) in adults (Lefly & Pennington, 2000), but it can also help measure risk in children, especially before school age. Reading disability is highly heritable: about 30-60% percent of children born to a dyslexic parent will develop dyslexia. Thus, one way to estimate risk of reading disability in preschool children is to evaluate parents’ own reading history. The following questionnaire was developed using parents’ reports of their own reading history as well as actual testing of their children’s reading skills. If a parent scores high on the ARHQ, their child has a higher risk of developing a reading disability. It is important to note that the ARHQ is only a screener and does not constitute a formal evaluation or diagnosis of either the parent or the child. If you have concerns about your child’s reading progress, we recommend that you contact your child’s school, a licensed child psychologist, or your child’s primary care physician about pursuing a more thorough evaluation to investigate the nature of these concerns.
The Adult Reading History Questionnaire (ARHQ) is a self-report screening tool designed to measure risk of reading disability (i.e. dyslexia) in adults (Lefly & Pennington, 2000). The ARHQ asks adults about their own reading history and current reading habits in order to estimate the risk that they may have a reading disability.
