Summary:
Zip code 39532 in the Biloxi, Mississippi area is served by two public high schools—Biloxi High School and D'Iberville High—both serving grades 9 through 12 but belonging to different districts. Biloxi High School is part of the Biloxi Public School District with an enrollment of 1,669, while D'Iberville High is in the Harrison County School District with 1,478 students.
Both schools earn 5-star ratings, but they lead in different areas. D'Iberville High is the academic standout, ranking 10th out of 224 Mississippi high schools for 2025–2026 (96th percentile), and it posts the strongest MAAP scores in nearly every subject, including 92.3% proficiency in Algebra I and 62.6% in English II. Biloxi High School, ranked 17th (92nd percentile), counters with a stronger graduation rate of 91.4%—above the state average of 89.2%—and a more favorable student-teacher ratio of 15.5 compared to D'Iberville's 18.1. Both schools far exceed state averages on standardized tests, with Algebra I proficiency roughly 23 to 26 points above the Mississippi average.
The most notable contrast is that D'Iberville High outperforms Biloxi High School on test scores yet graduates a smaller share of students (85.7%). Biloxi also posts higher chronic absenteeism (25.5%) despite its better graduation rate. D'Iberville achieves its academic edge while serving a slightly more economically disadvantaged student body (58.46% free/reduced lunch vs. 53.86%). Both schools followed a similar trajectory, dipping in 2024–2025 before rebounding to 5-star status in 2025–2026. Interestingly, Biloxi's smaller class sizes haven't translated into higher test scores, suggesting curriculum and instruction play a larger role than class size.
