Schools in Zip Code 29812

Zip code 29812 in Barnwell, South Carolina, is served by four public schools in the Barnwell district, which currently holds a 1-star rating and ranks 65th out of 75 districts in the state, enrolling roughly 1,997 students across elementary, middle, and high school levels.

For parents, the standout school in this area is Barnwell Elementary, which serves grades 4-6 and is the district's hidden gem. It boasts the lowest chronic absenteeism rate at just 8.7%—far better than the district average of 20.6%—and outperforms district averages in 7 of 8 tested subject and grade combinations. Its 6th grade ELA proficiency of 55% nearly matches the state average of 56.3%. In contrast, Guinyard-Butler Middle (grades 7-8) is the district's biggest challenge, with a 30.4% chronic absenteeism rate and only 19.4% proficiency in 8th grade math—less than half the state average of 44.2%. Barnwell High shows the most improvement, climbing steadily in state rankings, and posts strong English 2 proficiency at 72.4%, though its English 1 scores lag at 42.9%. Barnwell Primary (PK-3) shows solid 3rd grade ELA performance at 57.1% but struggles more in math at 43.6%.

The most striking pattern is the "middle school slide"—students leave Barnwell Elementary with relatively strong skills, but performance drops sharply at Guinyard-Butler, especially in math. This correlates with a 21.7 percentage point jump in chronic absenteeism between the two schools. Mathematics is a district-wide weakness, with every school falling 9 to 25 points below state averages. Interestingly, higher spending doesn't guarantee better results: Barnwell High spends the most per student ($15,013) yet doesn't outperform Barnwell Elementary, which spends the least ($13,758). The district's graduation rate of 80.3% is a bright spot, nearly matching the state average, suggesting schools keep students on track despite academic challenges.
