    Low literacy is a national crisis that affects all of us and our broader economy. The earlier we intervene, the larger impact we can make. By taking the time to understand the facts of this issue and working together to combat the literacy crisis head on, we can help to ensure children are getting the resources and attention they need to be strong readers and successful members of society.

    Together we can make a difference and transform the lives of our children and communities by getting involved in advocating for education and volunteering in schools.
