Summary:
Ruby, South Carolina is home to a single elementary school, Ruby Elementary, which serves students in grades Pre-Kindergarten through 5th grade with a total enrollment of 256 students, making it a small, community-focused school within the Chesterfield 01 school district.
For parents, the most important takeaway is that Ruby Elementary is a clear academic leader within its local district, consistently outperforming the Chesterfield 01 average in nearly every subject and grade level. The school is also on a strong upward trajectory, with its statewide ranking improving from the 37th percentile in 2023-2024 to the 50th percentile in 2025-2026. A standout highlight is the 5th-grade English Language Arts (ELA) proficiency rate of 72.1% in 2025-2026, which far exceeds both the district (53.5%) and state (63.6%) averages. The school also boasts a favorable student-to-teacher ratio of 11.6:1 and a chronic absenteeism rate of 19.0%, which is better than both the district (24.1%) and state (22.3%) averages—positive indicators for a supportive learning environment.
However, the picture is more mixed when comparing Ruby Elementary to the state as a whole. While the school meets or exceeds state averages in ELA, it lags behind in Mathematics and Science. For example, in 2025-2026, 4th-grade math proficiency was 42.0% compared to the state average of 52.3%, and 4th-grade science proficiency dropped sharply from 55.6% to 40.0% year-over-year—a concerning decline that warrants investigation. On the positive side, the school showed remarkable growth in several areas, including a 22.1 percentage point jump in 5th-grade ELA and an 18.7 point increase in 3rd-grade math. Overall, Ruby Elementary is a solid, improving school that excels locally, but parents should be aware that upper elementary math and science are areas where the school still has room to grow to reach top-tier statewide performance.
