Tests measuring visuospatial abilities have shown that these abilities increase during adolescence. Unfortunately, the Block Design test and other such tests are complicated and time-consuming to administer, making them unsuitable for use with large groups of restless adolescents. The results of the Design Organization Test (DOT), a quick pen-and-paper test, have been shown to correlate with those of the Block Design test. A group of 198 healthy adolescents (110 male and 88 female) aged 12 to 19 years old participated in this study. A slightly modified version of the DOT has been used in which we shortened the administration time to avoid a ceiling effect in the score. Scores show a linear increase with age (on average 2.0 points per year, r = .61) independent of sex. Scores did not differ between individual setting and group setting. Thus, the DOT is a simple and effective way to assess visuospatial ability in large groups, such as in schools, and it can be easily administered year after year to follow the development of students.
