100. PISA Scores 2024: US Math Skills Lag Global Peers

The latest results from the Programme for International Student Assessment (PISA) have triggered alarm bells across the American education system. While American students managed to hold their ground in reading and science, the data reveals a significant and worrying decline in mathematics proficiency. As educators and policymakers review these 2024 reports based on the most recent testing cycle, the gap between the United States and top-performing nations is widening.

The Math Crisis by the Numbers

The PISA exam is administered every three years by the Organization for Economic Cooperation and Development (OECD). It measures the ability of 15-year-olds to apply their knowledge in real-world scenarios. The most recent data paints a stark picture of American mathematical capability.

U.S. math scores plummeted by 13 points compared to the previous testing cycle. This drop brought the average U.S. score down to 465. For context, this is the lowest score recorded for the United States since the testing began in 2000. Perhaps more concerning is where this places the country globally: the U.S. is now statistically below the OECD average of 472.

This decline was not limited to struggling students. The drop occurred across the board. Low-performing students saw their scores decrease, but high-performing students also saw significant dips in proficiency. This suggests a systemic issue rather than a problem isolated to specific districts or demographics.

Global Competitors Leave the U.S. Behind

To understand the severity of the situation, you have to look at the leaderboard. While the U.S. struggles to meet the average, East Asian education systems continue to dominate the rankings.

Singapore secured the top spot with a commanding score of 575. To put that 110-point difference in perspective, the OECD equates roughly 20 points to a full year of schooling. This means the average 15-year-old in Singapore is mathematically roughly five years ahead of their American counterpart.

Other top performers included:

  • Macau (China): 552
  • Taiwan: 547
  • Japan: 536
  • South Korea: 527

Among European nations, Estonia and Switzerland also significantly outperformed the United States. The U.S. currently trails behind 25 other education systems in mathematics. This lag poses questions about the future competitiveness of the American workforce in a global economy that increasingly prizes data literacy and STEM skills.

The Silver Lining: Reading and Science

The news was not entirely negative. The United States performed surprisingly well in reading and science, showing resilience that many other nations lacked in the wake of the pandemic.

In reading, the U.S. ranked 6th globally. While the raw score dropped slightly, it dropped far less than the global average. American students maintained a score of 504 in reading and 499 in science. Both of these figures are well above the OECD averages.

This divergence creates a puzzling “two-track” reality for American education. Schools are successfully teaching students to analyze text and understand scientific concepts, yet they are failing to translate that success into mathematical fluency.

Analyzing the Causes

Pinpointing the exact cause of the 13-point math plunge is complex, but researchers point to a combination of pandemic-related learning loss and long-standing structural issues.

Pandemic Disruption Mathematics is a cumulative subject. If a student misses a foundational concept like fractions or pre-algebra, they cannot easily move on to algebra or geometry. The disjointed learning environments of 2020 and 2021 hit math instruction harder than reading. Parents found it easier to support reading at home than to teach high school level geometry or algebra.

Teacher Shortages The National Center for Education Statistics has highlighted a chronic shortage of qualified math teachers. Many schools, particularly in lower-income areas, are forced to rely on substitute teachers or instructors who are teaching outside their area of expertise.

Curriculum Disputes The U.S. has spent years debating how to teach math. The “Math Wars” often pit traditional memorization and standard algorithms against conceptual “inquiry-based” learning. While the debate continues, the lack of a unified, rigorous national standard makes it difficult to ensure every student receives the same quality of instruction found in centralized systems like Japan or Singapore.

Economic Implications of the Math Gap

This is not just an academic issue. It is an economic one. Stanford University economist Eric Hanushek estimates that the learning loss represented by these scores could lower the lifetime earnings of this cohort of students by 1.6%.

On a macro level, a workforce that lacks mathematical competence struggles to fill high-tech jobs. Industries ranging from artificial intelligence to advanced manufacturing require strong math skills. If the domestic workforce cannot supply this talent, companies often look to hire from the very countries that are currently outscoring the U.S. on the PISA exams.

Steps Toward Improvement

In response to these scores, several states are overhauling their approaches. We are seeing a shift back toward “science of math” instruction, which emphasizes structured practice and mastery of facts alongside conceptual understanding.

Additionally, the U.S. Department of Education has launched initiatives to boost high-dosage tutoring. This involves frequent, small-group instruction to help students catch up on the specific concepts they missed during the pandemic years. Evidence suggests this is one of the few interventions powerful enough to reverse the slide.

Frequently Asked Questions

What is the OECD average? The OECD average is the mean score of the 37 member countries of the Organization for Economic Cooperation and Development. For the most recent math assessment, the average was 472.

How often are PISA tests given? PISA tests are administered every three years. The most recent cycle was delayed by one year due to the COVID-19 pandemic (shifting from 2021 to 2022), with results released and analyzed heavily in late 2023 and 2024.

Why did U.S. reading scores stay high? Experts believe reading is more easily reinforced outside the classroom. Students read on screens, in books, and through social interaction. Math requires specific, sequential instruction that is rarely practiced casually in daily life.

Is this decline only happening in the U.S.? No. Math scores dropped globally by an average of 15 points. However, because the U.S. started with lower math scores than many peers, the drop pushed American students below the proficiency baseline, whereas top-tier nations dropped but remained high.

What grade level takes the PISA? PISA does not test a specific grade level. Instead, it tests 15-year-olds, regardless of what grade they are in, to assess the skills of students nearing the end of compulsory education.
