Against the backdrop of accelerated shifts toward digital instruction during the COVID‑19 pandemic, schools faced heightened needs for flexible, supplemental learning supports that address unfinished learning through targeted enrichment and remediation while providing appropriately challenging, scaffolded opportunities for sustained academic progress. This quasi‑experimental study examined the impact of Waggle® ELA on reading outcomes for 1,402 students in Grades 3–5 during the 2020–2021 school year in one Missouri school district, comparing students who used Waggle ELA with a matched group of peers who did not. Results showed that Waggle ELA students demonstrated statistically significant gains in reading achievement from mid-year to end-of-year despite a limited instructional window of approximately four months, with the strongest effects observed in Grade 3, including higher growth and a greater likelihood of meeting targeted growth expectations. These findings provide ESSA Moderate Evidence that Waggle ELA is an effective supplemental solution for supporting literacy growth in real‑world elementary classroom settings.
