PUBLISHED RESEARCH
An ESSA Tier 3 study designed and conducted by an independent third party has shown implementing In Tandem in intervention has statistically significant positive effects on students’ literacy achievement with a moderate-to-large effect size of approximately 0.65.
The study was conducted in one district in New York and used district-wide i-Ready assessment data from the 2024-25 school year to determine the relationship between In Tandem and student literacy performance in grades K–1. Overall, these results indicate that In Tandem produced a meaningful improvement in student literacy outcomes, exceeding typical gains expected from normal developmental progress.
An ESSA Tier 2 study designed and conducted by an independent third party has shown implementing Stepping Together and Phonics Launch to have statistically significant results. Using these whole-class and small-group literacy solutions can help students gain essential literacy skills at an accelerated rate.
The study was conducted in one district in Ohio and uses district wide i-Ready assessment data from the 2023-24 school year to determine the relationship between Stepping Together and Phonics Launch and student literacy performance in grades K–2.
JEM & R study finds that students who received instruction from Stepping Together and Phonics Launch made significantly greater reading achievement gains and had a higher rate of growth in reading performance than their peers in the control group whose teachers used different reading instructional programs.
The study was conducted in one district in Ohio and uses district wide assessment data from the 2023–24 school year to determine the relationship between Stepping Together and Phonics Launch and student literacy performance in grades K–2.
McREL Study Finds Literacy Footprints Meets Criteria for Tier 1 (Strong Evidence) under ESSA [PDF]
McREL researchers conducted a matched pair cluster randomized control trial to investigate LFP’s possible effects on student achievement.
A matched pair cluster randomized control trial was conducted during the 2021–2022 school year with 3,071 students enrolled in 29 public elementary schools in the School District of Manatee County, a large, suburban school district in Florida.
To examine the impact of Digital Reader on student learning, McREL conducted a quasi-experimental analysis comparing outcomes for students who used Digital Reader and those who did not across 31 elementary schools.
