An analysis of 2025 PISA data showed no simple correlation between total device time and academic performance, though usage patterns significantly influenced results. Findings indicate that moderate learning-focused device use correlates with higher science achievement across OECD countries.
Why it matters
Understanding these usage patterns helps families balance screen time for educational benefits without sacrificing focus or attendance. This insight is particularly relevant as schools refine policies regarding personal electronics in the classroom.
OECD students using devices for learning 2-3 hours daily scored higher in science than non-users, while 28% reported classroom distraction. Conversely, students using leisure devices for 4 or more hours daily showed significantly higher truancy rates.
The players
OECD
An international organization providing data and policy analysis on education systems and academic performance.
PISA
The Program for International Student Assessment, a standardized metric measuring student performance across global education systems.
The details
The research highlights that moderate integration of technology for learning can support science achievement, with scores peaking among those using devices 2-3 hours daily. However, excessive leisure usage, specifically exceeding 4 hours daily, correlates with increased class skipping. Furthermore, distraction remains a reported factor in science classrooms, affecting 28% of OECD students and 6.7% of students in Korea.

The Home Front
This analysis updates our understanding of digital integration in schools following the PISA 2025 science assessment. It challenges the assumption that total screen time is the sole driver of student success, pointing instead to specific usage habits.
Consider auditing how your student uses devices at home to ensure screen time prioritizes educational tasks over prolonged leisure. Discuss classroom rules with your child to help them minimize potential distractions during school hours.
The takeaway
The data suggests that moderate, structured device use for learning can support academic growth. Monitor your student for signs of classroom distraction and prioritize educational engagement over high-volume leisure screen time to support consistent attendance.
