Summary:
Waterloo, South Carolina is home to a single public school, Waterloo Elementary, which serves grades PK-5 and enrolls 254 students within the Laurens 55 district.
For parents, the most important takeaway is that Waterloo Elementary is a clear standout in an otherwise struggling district. While Laurens 55 ranks in the bottom 20th percentile statewide (1 star), this school has maintained a solid 3-star rating for three consecutive years, placing it in the 65th percentile of all South Carolina elementary schools. The school benefits from exceptional resources, including a very low student-to-teacher ratio of 8.5:1 and high per-student spending of $17,444. Attendance is also a major strength, with a chronic absenteeism rate of just 11%—less than half the state average of 22.3%. Academically, the school dramatically outperforms its district, with 4th-grade math proficiency at 83.9% versus the district's 42.8%, and 5th-grade ELA at 78.3% versus 48.1%.
However, the data reveals significant year-to-year volatility that parents should be aware of. The most striking example is 5th-grade math, which jumped from just 20.8% proficiency in 2024-2025 to 65.2% in 2025-2026—a massive swing likely driven by small class sizes and different cohorts. Similarly, 3rd-grade scores dropped sharply from 88.6% to 53.8% in ELA over the same period. On a positive note, tracking cohorts shows sustained growth: the strong 3rd graders from 2024-2025 maintained their performance as 4th graders (87.1% ELA), and the 4th graders from that year continued to do well in 5th grade (78.3% ELA). This suggests the school builds on early strengths, but the uneven grade-level results indicate that resources alone don't guarantee uniform success. Overall, Waterloo Elementary is a high-performing school worth considering, especially given its excellent teacher ratios and strong attendance, though parents should expect some variability in outcomes from year to year.
