The assessment of human activities is an important task, because it helps to correct mistakes and to improve the overall performance of a group. Frequently, however, the individual assessment of the members of a group is performed not with numerical scores, but with qualitative grades (linguistic expressions). This happens either because the existing data are not exact, or for reasons of elasticity (e.g. teacher for students). In such cases the mean performance of the group cannot be assessed by applying the traditional method of calculating the mean value of the individual scores of its members. In this short communication, a method developed recently by the author is presented for evaluating the mean performance of a group in such cases, using grey numbers as tools. The method is illustrated by an example concerning the assessment of the mean performance of a class of students.
