"Magnetic Reading" is an evidence-based reading comprehension program for students in grades 3 through 5 built on four pedagogical pillars: knowledge-rich learning, culturally and linguistically responsive pedagogy, scaffolds to support learner variability, and data to inform instruction. This study uses a prospective matched comparison group quasi-experimental design to examine the impact of "Magnetic Reading." At the beginning of the 2022-23 school year, we used coarsened exact matching to match students in schools that used "Magnetic Reading" to students in schools that did not using student demographic characteristics and a fall achievement test score. We subsequently conducted an analysis of spring state achievement test scores on the post-attrition sample after establishing that the groups were similar on baseline characteristics. Our HLM analysis found a statistically significant impact of 8.4 points--an effect size of 0.22 standard deviations--on reading scores.
