“Harlacher is on a mission to simplify schools’ approach to implementing MTSS—and he succeeds! Unique among resources on MTSS, this book delivers practical guidance based on an understanding of what drives educators to accept and embrace change. Harlacher’s expertise has been built over decades of supporting schools in MTSS implementation. This book's five principles are essential for school leaders new to MTSS and for experienced implementers looking to inspire a renewed effort toward systems change.”

—Julie Q. Morrison, PhD, NCSP, School Psychology Program, University of Cincinnati


“It is not often that a book is able to address the needs of both MTSS beginners and experts, but MTSS Simplified does just that. This book addresses the critical need to make MTSS implementation more approachable through the powerful and engaging use of metaphors and real-world examples. While MTSS frameworks are often overly technical, Harlacher creates a clear roadmap for implementation. This book should be required reading for all building and district leaders involved in MTSS and other change efforts.”

—Karen Jensen, EdS, Mental Health Services Coordinator, Harrison School District 2, Colorado Springs, Colorado


“Harlacher knows that student outcomes don't improve unless adults change their behavior. This book will support school leaders who need to focus on the actions and activities that simplify the complexity of MTSS, university professors who train administrators and school psychologists to lead change in schools, professional development providers and coaches who want fresh ideas for change management, and any educator who says their school implements MTSS but they aren't getting results for students. Kudos to Harlacher for recognizing a need and responding with such a useful book!”
