Teen reading, math, and science scores have fallen to their lowest levels since international PISA testing began in 2000, with 15-year-olds now reading at roughly the level previously expected of students a year younger. The Organization for Economic Co-operation and Development (OECD) linked weaker results to more screen time, less reading for pleasure, and digital distraction. It also found that students who regularly used AI chatbots for tasks like drafting essays and summarizing text scored about 20 points lower in science, roughly equivalent to a year of learning. Reuters reports: A 2012 reading high of 501 on PISA's index had declined to a score of 466 last year. The test is widely regarded as the world's leading gauge of educational performance and its results are closely scrutinized by governments and educators. "In reading, more screen time and less reading for pleasure have gone hand in hand with weaker results," OECD head Mathias Cormann told a press conference. "We're also seeing more hasty reading, students rushing through a text and giving a quick wrong answer." Reading scores fell more sharply in students from better-off backgrounds, the study added. Hindered by falling reading standards, average teenage science and maths skills were also at their lowest this century. Science fell from a 2009 high of 506 on the index to 486, while maths was down from 502 to 469 in the same period. East Asia was the best-performing region. Chinese cities that participated in the test, Japan, Korea, Singapore and Taiwan had the best educational systems with Britain and Estonia the only countries outside the region that made it into the top 10 in reading, mathematics and science.
