“One common mistake that schools make when implementing a tiered intervention program is that they pull students from essential core instruction to provide remediation of prior skills—that is, Tier 2 interventions replace student access to Tier 1 core instruction. When students miss essential core instruction for interventions, they never catch up. This is because while the targeted student is receiving interventions to learn a prior skill, they are missing instruction on a new essential standard. Ask classroom teachers why they don’t like students “pulled out” of their class for interventions, and they will tell you: “Because the student misses what I am teaching now.” For these students, it is one step forward, two steps back.”
