Arizona Department of Education’s MTSS/RTI Guiding Principles are…


To collaboratively develop the capacity of all Arizona LEA’s to implement, and sustain a system of supports that prepares all students for college and career readiness.


To accelerate and maximize academic and behavioral outcomes for all students through the application of collaborative data-based problem-solving utilized by effective leadership at all levels of the educational system.


  1. ALL students will learn and achieve academic success as a result of effective teaching, early intervention and ongoing support.
  2. ALL students must have access to a rigorous, standards-based curriculum and research-based instruction delivered with fidelity.
  3. Collaboration among ALL stakeholders is the foundation of effective problem-solving and data based decision-making.
  4. A multi-tiered system of evidence-based interventions is essential for addressing the full range of student needs.
