This segment from Yale's Overcoming Dyslexia course continues a multi-part lesson on how clinicians and educators identify dyslexia in students. The instructor walks through specific diagnostic markers and assessment considerations, building on the reading and language-processing concepts introduced earlier in Lesson 6.3. The focus stays practical: what test results and behavioral signs point to a dyslexia diagnosis rather than another reading difficulty, and how examiners weigh those signs together. As the third installment in a sequence, it assumes familiarity with the earlier parts of the lesson and narrows in on the finer points of assessment rather than reintroducing the basics. The style is direct instruction aimed at students training to recognize and evaluate dyslexia in real cases.
