New Mexico's Three-Tier Model

Response to Intervention (RtI) frameworks vary from state to state. In New Mexico, the RtI framework is called The Three-Tier Model of Student Intervention. State rules require schools in New Mexico to organize their instructional program by using this three-tier approach to match all students with an appropriate level of instruction and/or intervention.

  • In Tier 1, all students are screened (universal screening) for potential problems. All students also receive appropriate, standards-based, core instruction including any classroom, grade-level, or school-wide interventions (universal interventions) for academics and behavior. Tier 1 universal interventions are provided in the general education classroom.
  • In Tier 2, students who have not responded significantly to the Tier 1 core program with universal interventions are referred to the school's Student Assistance Team (SAT) and may receive a targeted, individual intervention plan. This plan could include more intense instruction, individually or in a small group, and is provided in addition to the general education curriculum. Students with disabilities who do not qualify for special education services may also be served at this tier through a Section 504 accommodations plan.
  • In Tier 3, a student qualifies for special education services or the state criteria of gifted, and receives specially-designed instruction and related services through an Individualized Education Program (IEP).

In all tiers, a student is progress monitored to see if the instruction and/or interventions are effective. Then, using that data, instruction is adjusted accordingly. The graphic below illustrates the basic three-tier model of student intervention in New Mexico. Illustration of Three Tier Model
