Best High Schools in Zip Code 28115

Zip code 28115 is home to just one public high school, Mooresville High School, a large 9–12 campus enrolling roughly 1,923 students in the Mooresville Graded School District. Because there is no other high school in the immediate zip code, the most useful comparisons are to North Carolina state averages and to the district as a whole. Overall, Mooresville High shows a mixed but generally encouraging picture: it reports a strong 94.9% graduation rate (2022–23), sits below the state average for chronic absenteeism at 20.5% versus 24.2%, and serves a student body where about 41% qualify for free or reduced-price lunch.

Academically, the school’s End-of-Course proficiency scores improved meaningfully from 2024–25 to 2025–26 in most subjects. Math I posted the most dramatic gain, jumping from 27.7% to 46.6% proficient—moving from well below the state average to above it. English II also rose from 59.2% to 66.0%, exceeding the state rate of 64.6%, and Math III remained solid at 71.0% versus the state’s 68.9%. The one exception is Biology: despite improving from 47.8% to 55.4%, the school still trails the state mark of 58.5%. These gains have not translated into a better SchoolDigger ranking, however; the school has hovered near the 50th percentile (2 stars) for two straight years, after a 3-star showing in 2023–24. Notably, the district itself earns 4 stars and ranks in the 79th percentile of North Carolina districts, suggesting that the district’s strength comes substantially from its elementary and middle schools rather than from the high school.

For parents, the key takeaway is that Mooresville High is a large school with rising test scores, a high graduation rate, and above-average performance in reading and most math courses, but it still struggles with Biology and has seen its overall state ranking plateau near the middle of the pack. Chronic absenteeism, while better than the statewide average, affects more than one in five students and is higher than the district-wide rate of 17.5%, indicating that attendance is a bigger challenge at the high school level. Finally, the most recent spending-per-student figure of $8,785 dates back to 2018–19 and should be interpreted cautiously. In short, Mooresville High appears to be on a positive trajectory, with real momentum in math and reading—but it has yet to translate that progress into a higher star rating.
