Dr. Chris Weber formerly led the Instruction & Intervention Systems practice area of Houghton Mifflin Harcourt’s International Center for Leadership in Education (ICLE), applying his extensive Response to Intervention (RTI) expertise to support districts and schools in raising the level of learning for all students. As a principal and school district leader in California and Chicago, Dr. Weber co-developed systems of RTI that have led to heretofore unrealized heights of learning at schools across the country. He is the best-selling author of RTI Roadmap, among numerous other school improvement titles, and is also a recognized expert in behavior and mathematics.
