Everyone is talking about Multi-Tier System of Support (MTSS), but how does a school get started and ensure that what they are doing is working? ESSA recommends that educators receive professional development in MTSS and since its passage, schools have been scrambling to ensure that they are "doing MTSS." If done with fideility, MTSS ensures equitable access and opportunity for all students to achieve. However, without long-term, sustained help in both implementation and evaluation, many schools will not do it well and children will be negatively impacted. MTSS is complex. It is designed as an integrated, comprehensive framework that focuses on many different educational aspects: CCSS or other state standards, Tier One instruction, differentiated learning, student-centered learning, individualized student needs, and the alignment of systems necessary for all students' (special education students, ELs, gifted students among them) academic, behavioral, and social success. As members of the California Department of Education's MTSS Design Team Implementation, the Hannigans are the ideal authors for this audience and topic. As with their other Corwin books, this one will be highly engaging and practical. It will guide readers through an interactive process to help them understand the what, why, and how of effective MTSS implementation. Readers will learn how to audit, align, and coordinate their current practices, structures, interventions, and resources across all levels of the educational system in order to support ALL students. They will also learn how to effectively integrate a data-based decision-making and continuous improvement lens to monitor the effectiveness of implementation"--
