q3 i? Among students initially eligible for Tier 2, those fast-tracked immediately in Dynamic RTI scored significantly higher than those in Typical RTI who received Tier 2 only after not responding to Tier 1. → Al Otaiba 2015

q3 · i? · causal · r2

Subgroup contrast from the same randomized intent-to-treat HLM analysis (Table 1). The article reports the Tier 2 comparison as statistically significant but prints no effect size for it.

"Tier 2 students in the Dynamic RTI condition had significantly higher reading outcomes scores compared to students initially eligible for Tier 2 in Typical RTI, who by design only received Tier 2 if they did not respond to Tier 1 over the first or second session."

Discussion¶

Related Claims¶

• First graders assigned to Dynamic RTI scored significantly higher on spring reading outcomes than students assigned to Typical RTI, with a moderate effect size of .36 — a broader claim this one bears on
• Students initially eligible for Tier 3 who received Tier 3 intervention immediately achieved higher Brief Reading scores than Tier 3-eligible students who waited until Session 3 — related
