Triggered from the growing recognition of the impact of educational environments on student academic achievement, particularly through the lens of nature exposure, this national study analyzes NatureScore™ across over 65,000 U.S. schools, revealing significant disparities in access to surrounding natural environments. Schools with more economically disadvantaged students—especially in urban areas—tend to have lower NatureScores®. The findings advocate for integrating green infrastructure and nature-based learning into equity-focused educational and public health strategies.
