Students around the world suffered historic setbacks in reading and math during the COVID-19 pandemic, with declines in test scores so widespread that the United States climbed in global rankings simply by falling behind less sharply, a new study finds.
The state of global education was given a bleak appraisal in the Program for International Student Assessment, the first study to examine the academic progress of students in dozens of countries during the pandemic. Released Tuesday, it finds the average international math score fell by the equivalent of three-quarters of a year of learning. Reading scores fell by the equivalent of half a year.
The setbacks spanned nations rich and poor, big and small, with few making progress. In the countries where students were tested, a quarter are now considered low performers in math, reading and science, meaning they struggle to perform basic math problems or interpret simple texts.
Usually given every three years, the latest test was delayed a year because of the pandemic. It was administered in 2022 to a sample of 15-year-olds in 37 countries that are members of the Organisation for Economic Co-operation and Development, plus 44 other partner countries. The OECD has been conducting the test since 2000.
The new results point to an “unprecedented drop in performance,” the report says. It raises concerns about countries including Germany, Iceland and the Netherlands, which saw drops of 25 points or more in math scores. Twenty points is seen as equivalent to a year of learning.
Across all participating countries, the average math score fell by about 15 points since the 2018 tests. Reading scores fell by 10 points. Neither subject had seen a change of more than five points previously. The bright light was in science, where scores changed little since 2018.
