Gray Stone Day has remained stable over three years, holding a 4-star rating and a 77-78th percentile high school ranking each year, which indicates strong, consistent performance rather than a single standout cohort. The school’s very low chronic absenteeism likely supports both its academic success and high graduation rate. One limitation is that the data does not include free/reduced-price lunch information, so parents cannot assess the school in the context of student poverty levels. Overall, for families in this zip code, Gray Stone Day offers a top-tier, well-rounded education with excellent middle school and upper-level course results; its primary challenge is Math I, which mirrors the state average and deserves attention.
