Half of Portuguese 15-year-old students use artificial intelligence tools at least once a week to do schoolwork, according to data from the Programme for International Student Assessment (PISA) 2025.
The data reveals that frequent use of AI does not translate into better academic performance. On the contrary, students who use these tools most frequently show worse results in Science compared to their peers who use the technology less regularly.
The PISA 2025 results suggest that dependence on artificial intelligence for completing school tasks may be associated with lesser acquisition of knowledge and skills, particularly in the area of Science.
