Studies report fundamental differences in brain development and activation patterns between individuals with dyslexia and those without.

Dyslexia is a brain-based learning disability that specifically impairs a person’s ability to read.

Understanding Dyslexia:What are the Effects of Dyslexia

Signs of typical reading development and possible indicators of risk for dyslexia.

Understanding Screening: Sample Representativeness

Sample representativeness is an important piece to consider when evaluating the quality of a screening assessment. If you are trying to determine whether or not the screening tool accurately measures children’s skills, you want to ensure that the sample that is used to validate the tool is representative of your population of interest.

Understanding Screening: Bias

When evaluating the quality of any screening tool, it is important to determine whether or not the assessment is biased against different groups of students. We want to ensure that students do not receive higher or lower scores on an assessment for reasons other than the primary skill or trait that is being tested.
