Southside High School stands out as a high-performing school with consistent academic excellence. It has ranked in the top 20% of Louisiana high schools for three consecutive years, currently sitting at the 84th percentile. The school outperforms both its district and the state in every core subject tested—Algebra I, Geometry, English I & II, U.S. History, and Biology—for the 2024-2025 and 2025-2026 school years. Its graduation rate is an impressive 92.9%, well above the district (85.1%) and state (85.0%) averages, while its dropout rate of 1.0% is notably lower than the district's 2.9% and state's 3.1%. The student-teacher ratio is 21.3:1, and 34.53% of students are eligible for free or reduced lunch, indicating moderate socioeconomic diversity.
While the school's state percentile rank has slightly declined from 89th to 84th over three years, its test scores have not dropped—in fact, scores in Algebra I, English I, and U.S. History improved recently. This suggests other schools are improving faster, not that Southside High School is declining. An interesting contrast exists between its low dropout rate and a chronic absenteeism rate of 22.3%, which matches the state average. This implies strong intervention systems keep at-risk students from dropping out. Geometry (70% proficient) and Biology (67% proficient) are the lowest-scoring subjects, presenting opportunities for targeted improvement. Overall, this school offers a strong, supportive environment with high academic standards.
