South Carolina produced 54,980 graduates in the class of 2025. It is the largest graduating class in state history, the culmination of two trends moving in the same direction: a growing cohort and a rising graduation rate.

The cohort of 63,440 students was also a record. The 86.7% graduation rate was an all-time high. Put those together and South Carolina graduated 3,090 more students than the year before (a 6.0% increase) and 10,095 more than it did a decade ago.

The compound effect

Rising graduation rates and growing cohorts do not usually coincide. In many states, graduation rate improvements have come alongside declining enrollment: the denominator shrinks, making the percentage look better even when the same number of students finish. South Carolina's situation is different. The cohort grew from 54,340 in 2016 to 63,440 in 2025, a 16.7% increase. The rate climbed from 82.6% to 86.7%. The result is 22.5% more graduates over the decade.

That compound effect (more students entering the pipeline and a higher share of them finishing) produced the most graduates the state has ever seen.

By the numbers: 54,980 graduates. That is about 150 students per day crossing a stage somewhere in South Carolina, every day of the school year.

The trajectory since 2018

The graduate count dipped in 2021 (48,156) as both the cohort shrank and COVID disruptions took hold. Since then, growth has been continuous: 49,072 in 2022, 49,914 in 2023, 51,890 in 2024, and 54,980 in 2025. The 2025 jump of 3,090 graduates is the largest single-year increase in the data.

The cohort methodology change in 2018, which expanded who counts in the denominator, makes direct comparison to pre-2018 numbers unreliable for rates. But graduate counts are more robust to methodology changes: a graduate is a graduate regardless of how the cohort is defined. By that measure, South Carolina has been producing more graduates every year since 2021.

What 10,095 additional graduates means

The gap between the 2016 graduating class (44,885) and the 2025 class (54,980) is 10,095 students. Some of that increase comes from population growth. Some comes from better retention. Some comes from the 2018 cohort methodology change, which may have recategorized some students who would previously have been counted differently.

But even within the post-2018 era (comparing apples to apples) the state produced 6,761 more graduates in 2025 than in 2018. The rate improved from 81.0% to 86.7%, and the cohort grew from 59,540 to 63,440. Both factors contributed.

At the state level, 10,095 additional graduates per year compounds. Over a decade, that is roughly 100,000 more South Carolinians with high school diplomas than the 2016 rate would have produced. The downstream effects (on college enrollment, workforce participation, military eligibility, and lifetime earnings) are substantial, even if they are difficult to quantify precisely.

South Carolina's graduation rate is now within 0.3 percentage points of the national average of approximately 87%. For a state that has historically trailed national benchmarks in education outcomes, the convergence is significant. Whether the rate crosses the national average in 2026 depends on both South Carolina's continued improvement and whether the national average moves, but the gap has never been smaller.
