Sprayberry is currently navigating a period of change. Its state ranking has slipped from 91st (80th percentile) in 2024-2025 to 133rd (71st percentile) in 2025-2026, placing it mid-pack among its highly competitive neighbors. This decline coincides with a significant increase in the percentage of students qualifying for free or reduced lunch, which jumped from 35.99% in 2022-2023 to 48.56% in 2024-2025. Despite these shifts, the school shows clear strengths. It consistently outperforms both the district and state in U.S. History, with 57.7% of students proficient in 2025-2026 compared to 54% for the district and 38.5% for the state. Additionally, Sprayberry earns a 4-star rating for its work with African American, Hispanic, and Special Education students, indicating strong support for specific subgroups.

However, there are areas of concern. Algebra I proficiency is a persistent challenge, with only 41.8% of students proficient in 2025-2026, significantly below the district average of 59.4% and the state average of 48.1%. Chronic absenteeism is also elevated at 20.7%, compared to 14.2% for the district and 17.7% for the state. When compared to nearby schools, Sprayberry is most similar to Wheeler High School, which has nearly identical free/reduced lunch rates (48.94%) and chronic absenteeism (22.7%). However, Sprayberry outperforms Wheeler in U.S. History (57.7% vs. 35.4%) while posting similar Algebra I scores. In contrast, top-performing neighbors like Lassiter High School and Walton High School rank in the 96th-98th percentile, highlighting the competitive landscape. Overall, Sprayberry is a solid school with a distinct strength in social studies, a stable graduation rate, and clear areas for growth in math and attendance.
