When effort becomes optional: Why NC should end grade floors

When I first learned about so-called “grade floors,” I struggled to believe it.

A friend — who at the time served on a local South Carolina school board — told me that teachers in his district were barred from giving students below a 50% on their quarterly report cards.

The mandate came from the top, buried somewhere in the district’s grading manual and enabled by a local policy. Few could tell you how long it had been there, or how it arrived in the first place. What mattered is that teachers’ hands were tied from giving accurate grades. The message to students was clear: Effort was optional.

The school board’s decision to repeal the practice in 2024 became the catalyst for broader reform, revealing the prevalence of grade floors in other districts and laying the groundwork for change. Last month, South Carolina became the first state in the nation to legislatively ban grade floors.

North Carolina should be next.

Under a grade floor, sometimes called a “no zero” rule, students cannot receive below a pre-determined score (often 50% or 60%), even if they never hand in a single assignment during that period. Specifics can vary from school to school and district to district.

Proponents argue that such safeguards are necessary to help struggling students from falling behind. That a zero amounts to an academic death sentence, making recovery virtually impossible.

But like many well-intentioned policies, the unintended consequences have caused far more harm than good. Teachers in South Carolina — arguably the most vocal opponents of grade floors — have described how such rules were routinely abused and discouraged children from trying in class.

Consider this scenario: a student who completes little or no work during the first semester could still receive a 50% under a grade floor. If that student earned a 70% during the second semester, they would finish with a passing 60% average—even though they had effectively disengaged from half of the school year.

That’s the very outcome that minimum grades promote. By lowering expectations and removing any real consequences for failure, students are disincentivized from applying themselves and achieving at higher levels.

At least 10 — though likely more — local North Carolina school districts use some form of a grade floor, based on a 2025 review of their local policies. I stress “likely more” because grade floors vary in their application and don’t carry uniform language, making them hard to easily identify.

Sometimes they don’t stem from policy at all. In fact, I have spoken with a North Carolina teacher who is bound by a grade floor despite working in a district without an obvious policy to that effect. I suspect she isn’t alone.

What’s most clear is public opinion on the matter. The question of minimum grades was rejected by an overwhelming majority of likely North Carolina voters in 2025, with nearly 85% expressing disapproval of such policies, according to the Carolina Journal.

In neighboring South Carolina, the grade floor ban received support across the education community and ideological spectrum. Both major teacher associations — the SC Education Association and Palmetto State Teachers Association — embraced the measure, and the final bill garnered unanimous support from the state Senate (with only three no votes in the House).

North Carolina now has an opportunity to improve academic integrity in its schools through similar action. On the local front, school boards should review their policies and speak with district staff about whether grade floors are being used. Any rules directing teachers to assign grades inconsistent with students’ academic performance should be examined and ultimately removed.

The legislature or NCDPI could accelerate this process by directing districts to report whether such practices are in use. For maximum effect, lawmakers should consider a statewide ban as more information becomes available.

The dilution of modern academic standards is one of the greatest threats to students’ long-term prosperity. Grade floors are a key aspect of this decline — coupled with broader grade inflation, the erosion of AP standards, and the growing disconnect between graduation rates and true college and career readiness. What sets them apart is that they can be addressed directly and decisively, evidenced by South Carolina’s bold action last month.

Now, it’s North Carolina’s turn to ensure grades are honest and accountable. Doing so will keep students on a path to success and encourage them to reach their highest potential.
