DI: What's it all about? DI: Success for Every Student. Teachers all over the United States are seeking new and better ways to meet the needs of all of their students so that they can reach their full potential and be successful academically.

Implementing the concepts and principles of differentiated instruction is one way to begin closing this gap. Carol Tomlinson. Dare to Differentiate.
