Seoul: South Korean 15-year-olds' reading ability dropped significantly over the last three years, an OECD report showed Tuesday, likely partly due to the increased use of digital and social media.

According to Yonhap News Agency,the cohort's average reading score was 501, down 14 points from the previous assessment in 2022. The latest assessment was conducted over three years involving approximately 760,000 students in 91 countries, including 38 OECD member states. It aims to assess and compare 15-year-olds' skills in reading, mathematics, and science across countries, and has been carried out every three years, though the next editions will be released every four years.

In South Korea, the latest assessment was conducted on 6,859 students at 196 schools. The reading score ranked the country third to 13th, compared with second to 12th in 2022. The report assigns ranking ranges to each country instead of a single rank in consideration of the margin of error. "It is difficult to identify a single cause for lower reading scores across the world," an education ministry official said, referring to findings that Singapore, the top-ranked country in both 2022 and 2025, also saw a decline from 543 to 535 in the same period. Japan, meanwhile, retreated from 516 points in 2022 to 503 in 2025.

"It appears that a combination of things, such as (students') motivation and attitude toward reading, were affected by the increased use of digital and social media," the official said. South Korean students' average scores in mathematics and science also fell over the three-year period, but the decline was statistically negligible -- from 527 to 522 in mathematics and from 528 to 526 in science -- the report showed.
