Summary:
Zip code 29853 in Williston, South Carolina, is served by three public schools within the Barnwell School District, which collectively educate 637 students from pre-kindergarten through 12th grade.
For parents, the standout school in this area is Kelly Edwards Elementary, which earns a 2-star rating and ranks in the 40th percentile statewide—far exceeding the district's overall 13th percentile standing. This school outperforms state averages in 3rd and 5th grade English Language Arts and 5th grade math, with 5th grade math proficiency (51.2%) running 21.5 percentage points above the district average. Williston-Elko Middle also earns 2 stars and shows a remarkable "middle school surge," where 8th graders exceed state averages in both ELA (+7.0 points) and math (+8.1 points), despite 6th graders lagging significantly behind. The middle school also boasts the best student-to-teacher ratio in the area at 9.9:1. Unfortunately, Williston-Elko High represents a sharp drop-off, earning just 1 star and ranking in the 13th percentile. Its U.S. History proficiency rate of 30.6% is 32 points below the state average, and English 2 proficiency trails the state by 17 points.
The most concerning pattern is the decline in performance as students advance. While elementary and middle school students show promise—especially the exceptional 8th grade cohort—high school results suggest those gains are not sustained. Mathematics is a consistent weakness across nearly all grades, with 7th grade math proficiency at just 18.8%, the lowest rate in the entire dataset. With only 637 students spread across three small schools, resource constraints may play a role, particularly at the high school level with its 14.2:1 student-teacher ratio. Parents should note that while the elementary and middle schools are performing above district expectations, the transition to high school appears to be a critical challenge point for student achievement.
