Summary:
Zip code 71259 in Mangham, Louisiana, is home to a single high school, Mangham High School, which serves grades 9 through 12 with a total enrollment of 294 students and is part of the Richland Parish school district.
Mangham High School stands out as a clear academic leader within its district, consistently outperforming the Richland Parish average in every tested subject for both the 2024-2025 and 2025-2026 school years. For example, in the most recent testing, 55% of students were proficient in Algebra I compared to the district's 35%, and 43% were proficient in Geometry versus the district's 28%. The school also boasts a strong graduation rate of 94.3%, significantly higher than the district's 84.7% and the state's 85.0%, and a low dropout rate of 1.6%, which is less than half the district rate of 4.3%. Chronic absenteeism at 17.5% is also better than the district average of 21.1%.
Despite these local successes, a critical concern is the school's declining state ranking. Mangham High School dropped from the 35th percentile in 2023-2024 to the 23rd percentile in 2025-2026, and its star rating fell from 2 to 1. This suggests that while the school performs well relative to its district, other schools across Louisiana are improving at a faster pace. Additionally, there is a notable gap between the school's high graduation rate and its lower proficiency rates on state tests, such as 41% in English I and 41% in U.S. History. With 59.52% of students eligible for free or reduced lunch and a student-teacher ratio of 19.2:1, the school faces economic challenges, but its strong local performance indicates effective teaching and leadership that could be leveraged to reverse the downward state ranking trend.
