“…Movement among each tier may occur throughout the academic year based on data obtained from progress monitoring and/or benchmarking measures. Within an RtI framework, the approximate expected percentages of children in Tier 1, Tier 2, and Tier 3 are 80%, 15%, and 5%, respectively (Buysse & Peisner-Feinberg, 2010; Fuchs et al, 2012; Griffiths et al, 2007; Hosp et al, 2016; Stoiber & Gettinger, 2016). When children are meeting benchmarks as indicated through universal screening data and progress monitoring data, this typically suggests that the existing Tier 1 instructional quality is adequate for the context (Ardoin et al, 2016; Buysse & Peisner-Feinberg, 2010).…”
