One in five American children has a hard time learning to read. Many of these kids have dyslexia. There are proven ways to help people with dyslexia learn, and a federal law that’s supposed to ensure that schools provide kids with help. But across the country, public schools are denying children proper treatment and often failing to identify them with dyslexia in the first place. This APM Reports documentary investigates why and explores how improving things for dyslexic kids could help all students learn to read better.
