Designed for teachers and administrators grappling with the development and implementation of Response to Instruction and Intervention, more commonly referred to as RTI. No matter where you are in the process of developing your RTI system, we are certain that this common sense approach will provide valuable insights and practical steps. The great promise of RTI is the potential to reach and teach all students. That promise becomes a reality when the heart of an RTI system is a well-designed, TIER 1 program taught by well-prepared teachers who recognize the power of data to inform instruction. When all students receive good first instruction in such a system, the number of referrals for intervention goes down, proficient students maximize their learning, and gifted students grow intellectually. Drawing on their experience with thousands of educators, the authors offer a step-by-step process for constructing a strong TIER 1 curriculum, identifying the essentials of data-driven instruction, and analyzing instructional strategies that lead to good first instruction for all students. In our effort to translate the intent of RtI into practice, our observations and experiences with hundreds of educators have led us to focus on TIER 1. Even though what to use, when to use it, and how to access intervention in TIERS 2 and 3 are essential questions in an RTI model, we focus on the TIER 1 classroom as the foundation of a successful RTI implementation. Our purpose is to provide a blueprint for the kind of instructional planning and decision-making that maximizes learning for all students--those who are proficient and advanced, as well as those who require intervention services. Making an investment in effective instruction for TIER 1 classrooms reduces expenditures by minimizing referrals for more intensive and expensive instructional support. A strong TIER 1 is cost effective for everyone--administrators, teachers, and students. Each chapter in the book guides you through a process designed to zero in on critical aspects of TIER 1 instruction--those aspects that when addressed contribute to teacher success and student achievement. Section 1 focuses on several critical instructional variables--what to teach, how to teach, and how to determine what students have learned. Section 2 takes the next step and demonstrates how these variables play out in effective TIER 1 instruction. Using data to guide instructional decisions and assess student progress are at the heart of
