There is no way for an author to write without drawing from a wealth of people who are willing to share their wisdom and provide encouragement. Many thanks go to all the schools who were willing to try new ideas and share tried-and-true ones. The questions you asked, the deep caring you showed for your students, and the problems we solved together helped refine and develop the ideas in this book.

I am especially indebted to Sycamore Community Schools in Cincinnati, Ohio for allowing me to be a partner in their day-to-day celebrations and struggles as they implemented the RTI process over several years. This experience has been worth its weight in gold.
