Abstract
This study examined sex differences among academically achieving and underachieving gifted students (N = 280) in the Netherlands attending a pre-university track in secondary school. We focused on three types of underachievement: general, language arts, and STEM. Boys demonstrated higher general intelligence scores than girls, while girls showed higher general academic achievement than boys. No sex differences were found in language arts and STEM achievement. Furthermore, boys underachieved at higher rates than girls across all three achievement domains (general, language arts, and STEM). Students who underachieve in one domain are more likely to underachieve in another. Regarding social-emotional characteristics, the study identified differences between achievers and underachievers in academic-achievement motivation and social-emotional well-being, but not in academic self-concept and inquisitiveness. Our findings highlight the importance of early identification of underachievement in gifted students across multiple domains.
Plain Language Summary
This study looked at whether boys and girls with high intelligence perform differently in school and what factors might explain any differences. Researchers studied 280 Dutch seventh-grade students who were all attending an academically challenging pre-university track. The key findings showed that while boys scored slightly higher on intelligence tests, girls actually performed better in school across all subjects—including general academics, language arts, and science/math courses. Boys were about twice as likely as girls to be “underachievers”—meaning their school grades were much lower than expected based on their high intelligence. The researchers found that underachievement often affects multiple school subjects at once rather than just one area. For example, three-quarters of students who underachieved in language arts also underachieved in science and math. This pattern was especially strong for boys. Students who underachieved showed lower motivation for schoolwork and reported feeling less emotionally well compared to their achieving peers. However, both achieving and underachieving students showed similar levels of curiosity and confidence in their academic abilities. These findings suggest that having high intelligence does not automatically lead to good grades, and that boys may face particular challenges in translating their abilities into academic success. The results highlight the importance of identifying underachieving students early and providing support that addresses not just academic skills but also motivation and emotional well-being. Understanding these patterns can help teachers and parents better support all gifted students in reaching their potential.
