Research Brief: Reveal K–5

Johns Hopkins University’s Center for Research and Reform in Education conducted a study evaluating McGraw Hill’s Reveal Math program for grades K–5 during the 2022–23 school year. The research included 8,625 students, 185 teachers, 15 schools, and two districts. The participating districts represented diverse demographics, including Black, Hispanic, White, and other student groups.

The study compared math achievement between students using Reveal Math and those in a matched virtual comparison group with similar prior achievement and demographics. Results showed that Reveal Math students achieved higher average growth on the NWEA MAP Math assessment than comparison students, with an average gain of 0.8 points—equivalent to about 0.08 standard deviations, a small to moderate positive effect. Gains were strongest in the suburban district and among students in grades 3–5, who outperformed peers by 2–3 points.

Teacher feedback was highly positive. Educators praised the program’s lesson design, alignment with standards, and clear instructional guidance. Many noted improvements in student engagement and achievement, particularly in later elementary grades. One teacher described a “very big jump” in math scores, attributing growth to the new series, while another highlighted how easily the program integrates with state standards.

Overall, the study met criteria for ESSA Tier 2 (moderate evidence), confirming Reveal Math’s effectiveness in supporting elementary student math achievement and engagement across diverse school settings.
