The ability to communicate well—to read, write, listen, and speak—runs to the core of human experience. Language skills are essential tools not only because they serve as the necessary basis for further learning and career development but also because they enable the human spirit to be enriched, foster responsible citizenship, and preserve the collective memory of a nation.

Students who read well learn the tempo and structure of language early in their development. They master vocabulary, variance in expression, and organization and skill in marshaling evidence to support an idea. National Institutes of Health studies indicate that students who are behind in reading in grade three have only a 12 to 20 percent chance of ever catching up.
