Abstract
This study addresses the question whether highly gifted students have particular school-related problems. To answer this question, 4 categories of gifted students are compared, consisting of above-average intelligent students (IQ between 110 – 119), mildly gifted students (IQ between 120 – 129), moderately gifted students (IQ between 130 – 144), and highly gifted students (IQ above 144) with respect to underachievement and underattainment, as well as with respect to their scores on social-emotional and school-related behavior measures. All together, 3,442 students participated. It turns out that moderately and highly gifted students do not have particular problems at all. The category of mildly gifted students, however, could be labeled as a problematic category. Within this category, we found the highest percentage of underachievers and also the highest percentage of students whose school career was unsuccessful.
