A major new study from Norway has found that children born later in the school year—those who are the youngest in their class—are significantly more likely to be diagnosed with mental health problems than their older classmates. The research, which analyzed data from over one million children, has ignited global debate over how education systems, including Thailand’s, may inadvertently disadvantage their youngest students through rigid school entry cut-off dates. Experts are now urging policymakers and educators to reconsider age-based class placements and provide additional support to mitigate these long-term mental health risks.
