The Shifting Landscape of Failing Grades in American Schools
For decades, American students and parents have associated the number 70 with academic survival. Scoring below this threshold often meant a glaring “F” on report cards, signaling failure to meet expectations. But was this cutoff truly a universal standard before the pandemic disrupted education systems? The answer reveals a surprising lack of consistency in grading policies across the U.S.—and raises questions about how schools define success in the first place.
A Patchwork of Policies
Contrary to popular belief, the U.S. has never had a federally mandated grading scale. Education remains largely decentralized, with states and even individual school districts setting their own benchmarks. While a 70% cutoff for failing grades became common in many regions, notable exceptions existed long before Covid-19.
In Texas, for example, state law historically required districts to use a 70% minimum passing grade—a policy that influenced neighboring states like Oklahoma and Arkansas. Meanwhile, schools in California and New York frequently used 60% as the failing threshold, reflecting more flexible interpretations of student performance. Rural districts in the Midwest sometimes adopted hybrid models, where a 65-69% range might trigger interventions rather than outright failure. These variations stemmed from differing philosophies: Some communities prioritized strict academic rigor, while others emphasized opportunities for improvement.
The “70% Standard” Myth
The perception of 70% as a nationwide failing grade likely arose from textbook publishers and standardized testing frameworks, which often aligned materials with this midpoint. Additionally, college admissions processes indirectly reinforced the idea by encouraging high schools to adopt uniform grading scales for transcript clarity. However, a 2018 study by the National Center for Education Statistics found that only 62% of U.S. high schools explicitly defined anything below 70% as failing. The rest used scales ranging from 60% to 75%, with some alternative schools eliminating percentage grades altogether in favor of competency-based assessments.
This inconsistency created challenges. A student moving from a 60%-fail district to one requiring 70% could suddenly find themselves in academic jeopardy despite no change in effort or understanding. Teachers also grappled with fairness questions: Was a 69% essay in one classroom truly equivalent to a 59% paper in another?
Pre-Pandemic Pressures for Change
Even before 2020, educators debated whether traditional percentage grades accurately reflected learning. Research showed that rigid pass/fail cutoffs disproportionately affected marginalized students, including those from low-income households and non-native English speakers. Schools in cities like Portland and Denver began experimenting with “mastery grading,” where students could retake assessments until reaching proficiency, effectively decoupling grades from arbitrary numeric thresholds.
The pandemic accelerated these conversations. When remote learning exposed gaps in resources and accessibility, many districts temporarily lowered passing requirements or adopted pass/incomplete systems. For instance, Los Angeles Unified School District set 50% as the minimum passing grade during the 2020-2021 academic year to account for pandemic-related stressors. While controversial, these changes forced a broader reckoning: If emergency adjustments could prevent mass failures during crises, were pre-Covid standards too inflexible in ordinary times?
The Legacy of Flexibility
Post-pandemic grading policies reveal lasting shifts. Some districts, like Chicago Public Schools, permanently replaced D grades (traditionally 60-69%) with a “passing but needs improvement” designation to reduce stigma. Others introduced “no-zero” policies, setting 50% as the lowest possible score to give struggling students mathematical room to recover.
However, the 70% benchmark hasn’t disappeared. States with strong college-prep cultures, such as Massachusetts and Virginia, largely maintained their pre-Covid failing thresholds, arguing that high expectations drive achievement. This duality highlights a central tension in American education: balancing accountability with empathy, standardization with individuality.
What Defines Failure Anyway?
Beneath the numbers lies a deeper question about the purpose of grades. As education researcher Ken O’Connor notes, “A 70% cutoff assumes all content is equally important and that averaging scores over time provides meaningful feedback—both flawed premises.” Modern advocates for reform argue that grades should reflect skill mastery rather than point accumulation, making numeric cutoffs less relevant.
For now, the U.S. education system remains a mosaic of approaches. While the pandemic didn’t invent grading debates, it amplified demands for systems that recognize diverse learning journeys. Whether a student’s 68% represents failure or a stepping stone depends less on national standards and more on local philosophies—a reality that predates Covid-19 and continues to shape classrooms today.
