Summary:
Zip code 39150 is served by a single high school, Port Gibson High School, part of the Claiborne County Public Schools district. The school enrolls 381 students in grades 9 through 12, and every single student qualifies for free or reduced-price lunch — an indication of the high level of economic need in this area. With a student-teacher ratio of 11.5, the school maintains relatively small class sizes compared to many other high schools across the state.
Port Gibson High School is the standout — and only — high school in this zip code, so all district-level indicators mirror the school's own performance. One of its brightest spots is the graduation rate of 92.5%, which tops the Mississippi state average of 89.2%. However, the school's state ranking has slipped sharply in recent years, falling from the 36th percentile in 2023–2024 to just the 12th percentile in 2025–2026, with its star rating dropping from 2 stars to 1 star. Chronic absenteeism is a major concern: 51.9% of students were chronically absent in 2023–2024, more than double the state rate of 23.9% and well above the district figure of 30.5%.
Academically, Port Gibson High School trails the state average in every MAAP end-of-course subject tested. In 2025–2026, Algebra I proficiency was 53.6% versus the state's 66.0%, English II was 25.0% versus 49.3%, and Biology was 40.0% versus 63.1%. Proficiency also declined from the prior year in every subject with comparable data, most notably Algebra I, which dropped 13 percentage points. Even so, the favorable student-teacher ratio gives the school a structural asset to build on — if paired with targeted interventions to improve attendance and academic support, it could help reverse the current downward trend.
