Summary:
Zip code 39540 contains just one middle school—D'Iberville Middle School—serving grades 4 through 8 with 503 students in the Harrison County School District. The school is a strong performer despite serving a student body where 99.2% qualify for free or reduced-price lunch, earning 4 stars and ranking 55th out of 260 Mississippi middle schools (79th percentile) for 2025–2026. It has held a 4-star rating for three consecutive years, placing it comfortably in the top quarter of schools statewide.
Academically, D'Iberville's biggest strength is mathematics. In 6th grade, 72.2% of students scored proficient compared to 52.7% statewide; in 7th grade, 74.3% were proficient versus 57.7% statewide. The school also beat its district in 4th, 5th, 6th, and 7th grade math. English language arts performance is more mixed: 4th and 5th graders shine (62% and 64% proficient), but 7th and 8th grade ELA are weaker (45.8% and 44%), and 8th grade ELA fell sharply from 61.6% the previous year—a drop of nearly 18 points that deserves attention. Science results are above state averages (72.8% in 5th grade, 62.0% in 8th) but slightly behind the Harrison County School District.
Attendance is a notable bright spot. D'Iberville's chronic absenteeism rate is just 14.4%, much better than the district's 21.1% and the state's 23.9%, and the student–teacher ratio of 13.7 keeps class sizes relatively small. Given the school's very high poverty rate, consistent attendance and strong math scores point to effective instruction and a supportive school climate. Families considering this school should feel confident in its overall performance, while keeping an eye on upper-grade reading and science relative to the district.
