The most recent federal count, from the NCES directory, is 1,474 students in 2023-24, with 77 full-time-equivalent teachers, about 19.1 students per teacher. The state’s 2025-26 report card counts 84.7 full-time-equivalent teachers; it does not show a newer enrollment figure.

State report card

D’Iberville High earned an A for 2025-26, with 796 of 1,000 possible points, in the Mississippi Department of Education’s results file, released Oct. 15, 2026. A high school needed 769 points for an A this year, according to the state’s guide to the system (PDF). The Harrison County School District as a whole earned an A, with 711 points.

From the school’s 2025-26 report card:

Measure D’Iberville High, 2025-26
English (English II) proficiency 62.6%
Math (Algebra I) proficiency 86.2%
Science (Biology) proficiency 82.9%
English growth, all students 79.8%
Math growth, all students 98.3%
Four-year graduation rate 93.0%
Acceleration (advanced courses) 78.6%
Chronically absent students 18.1%

Mississippi grades every school and district from A to F. The state’s guide (PDF) says the grade counts proficiency and growth on state tests in English and math, with extra weight on the lowest-performing 25% of students, science, English learners’ progress and, for high schools, the graduation rate, advanced courses and college and career readiness. Because the writing part of the English test was field tested in 2026, the state used the higher of the 2025-26 or 2024-25 English results, and it says 2025-26 grades set a new baseline that “cannot be compared” to earlier years.
