All 11 schools are rated 4 or 5 stars, with the lowest-ranked school, Eldersburg Elementary, still in the 88th percentile statewide. The free/reduced lunch range is narrow (12.44% to 20.79%), indicating a generally affluent community. The data reveals a clear feeder pattern where middle school math success predicts high school performance, and chronic absenteeism serves as a leading indicator of academic outcomes. This is a community of high achievers where the main differentiator is how exceptional a school is relative to an already high bar.
