Tier One
Within Tier 1, all students receive high-quality, scientifically based instruction provided by qualified personnel to ensure that their difficulties are not due to inadequate instruction. All students are screened on a periodic basis to establish an academic and behavioral baseline and to identify struggling learners who need additional support. Students identified as being “at risk” through universal screenings and/or results on state- or districtwide tests receive supplemental instruction during the school day in the regular classroom. The length of time for this step can vary, but it generally should not exceed 8 weeks. During that time, student progress is closely monitored using a validated screening system such as curriculum-based measurement. At the end of this period, students showing significant progress are generally returned to the regular classroom program. Students not showing adequate progress are moved to Tier 2.
