Summary:
Zip code 70633 in DeQuincy, Louisiana, is home to a single high school, DeQuincy High School, which serves 279 students in grades 9-12 within the Calcasieu Parish school district.
DeQuincy High School presents a complex picture. On one hand, it boasts a very low student-teacher ratio of 9.4:1, suggesting small class sizes and potential for individualized attention. The school also has an excellent dropout rate of just 0.7%, far better than the state average of 3.1%, and its district graduation rate of 93.2% is well above the state's 85%. However, the school is facing significant challenges. Its state ranking has dropped sharply over three years, from a 4-star rating (75th percentile) in 2023-2024 to a 2-star rating (45th percentile) in 2025-2026. A major red flag is the chronic absenteeism rate of 30.6%, which is nearly 50% higher than the district average and a likely driver of academic struggles. Test scores in 2025-2026 show a dramatic one-year decline across all subjects, with U.S. History being a critical weakness at only 35% proficiency (20 points below the state average), while Geometry (61%) and English II (66%) remain relative bright spots.
The key takeaway for parents is that DeQuincy High School is a small school with strong potential due to its low dropout rate and small class sizes, but it is currently in a steep decline. The high chronic absenteeism rate is a systemic issue that appears to be undermining academic performance. While the school excels at keeping students enrolled, the next critical step is improving daily attendance and addressing the sharp drop in core subject proficiency, particularly in Algebra I and U.S. History. The school's small size could be a powerful asset for targeted interventions if the trend can be reversed.
