New International Comparisons of Reading, Mathematics, and Science Literacy Assessments

The Program for International Student Assessment (PISA) is a study of 15-year-old students’ performance in reading, mathematics, and science literacy that is conducted every 3 years. The PISA 2018 results provide us with a global view of U.S. students’ performance compared with their peers in nearly 80 countries and education systems. In PISA 2018, the major domain was reading literacy, although mathematics and science literacy were also assessed.

In 2018, the U.S. average score of 15-year-olds in reading literacy (505) was higher than the average score of the Organization for Economic Cooperation and Development (OECD) countries (487). Compared with the 76 other education systems with PISA 2018 reading literacy data, including both OECD and non-OECD countries, the U.S. average reading literacy score was lower than in 8 education systems, higher than in 57 education systems, and not measurably different in 11 education systems. The U.S. percentage of top performers in reading was larger than in 63 education systems, smaller than in 2 education systems, and not measurably different in 11 education systems. The average reading literacy score in 2018 (505) was not measurably different from the average score in 2000 (504), the first year PISA was administered. Among the 36 education systems that participated in both years, 10 education systems reported higher average reading literacy scores in 2018 compared with 2000, and 11 education systems reported lower scores.

The U.S. average score of 15-year-olds in mathematics literacy in 2018 (478) was lower than the OECD average score (489). Compared with the 77 other education systems with PISA 2018 mathematics literacy data, the U.S. average mathematics literacy score was lower than in 30 education systems, higher than in 39 education systems, and not measurably different in 8 education systems. The average mathematics literacy score in 2018 (478) was not measurably different from the average score in 2003 (483), the earliest year with comparable data. Among the 36 education systems that participated in both years, 10 systems reported higher mathematics literacy scores in 2018 compared with 2003, 13 education systems reported lower scores, and 13 education systems reported no measurable changes in scores.  

The U.S. average score of 15-year-olds in science literacy (502) was higher than the OECD average score (489). Compared with the 77 other education systems with PISA 2018 science literacy data, the U.S. average science literacy score was lower than in 11 education systems, higher than in 55 education systems, and not measurably different in 11 education systems. The average science literacy score in 2018 (502) was higher than the average score in 2006 (489), the earliest year with comparable data. Among the 52 education systems that participated in both years, 7 education systems reported higher average science literacy scores in 2018 compared with 2006, 22 education systems reported lower scores, and 23 education systems reported no measurable changes in scores.

PISA is conducted in the United States by NCES and is coordinated by OECD, an intergovernmental organization of industrialized countries. Further information about PISA can be found in the technical notes, questionnaires, list of participating OECD and non-OECD countries, released assessment items, and FAQs.
