Leisure time is undoubtedly part of human everyday life. It has been known ever since the Greek and Roman times. The aspect of leisure time has experienced many changes throughout the history. However, since the period of industrialization, leisure time has been increasing compared with work hours. An increased amount of leisure time raises the question of its quality. One of the best ways for children and youth to spend their leisure time is participation in organized activities that can be extracurricular or after-school. Taking into account the importance of quality leisure time, this paper researches pupils inclusion in extracurricular and after-school activities. These programmes are of great importance for children and youth as, in addition to mastering the content of activities, they offer much more, this including the development of creativity, discovering new talents, organization of their own time as well as cooperation with other pupils, and teachers. Teachers engagement in implementation of extracurricular activities is also researched as such activities are, according to the Croatian Laws, a mandatory programme. Since the total annual number of hours of extracurricular activities is only 35, it is very important for these activities to be carried out continuously. Although their implementation is governed by the law, pupils are not obliged to take part in them. The survey was carried out on pupils and their teachers (one teacher for all teaching process), both samples being collected in the Town of Dubrovnik. Two questionnaires were prepared for this survey, for pupils and teachers, respectively. The empirical interpretation of the results shows which extracurricular and after-school activities pupils mostly choose, their satisfaction as well as the reason for participating in the same. The continuity of activities, teachers opinion on the organization and the function of the extracurricular activities were also examined.
