Evidence for ESSA

A series of studies satisfying the ESSA Tier III (Promising Evidence) requirements demonstrates statistically significant, positive effects of using Happy Numbers on end-of-year math scores for grade K—5 students. This effect remains consistent above and beyond differences observed due to having different teachers and starting at different levels.

The 2021-2022 study focused on kindergarten and first-grade students. Find ESSA Tier III research highlights for these grades here, and access the complete report via this link.
