A large-scale competitive event demands extensive organizational activities. The paper aims to determine the success of a major competitive event by applying statistical analysis of secondary data systematically collected during the event. The paper analyzes the case of the international Millennial Creative Industries Competition, which has been held annually in December at the Faculty of Economics in Osijek since 2019. The Millennial Creative Industries Competition is designed to encourage young creatives across all educational levels to develop critical thinking, innovative problem-solving approaches, teamwork, and presentation skills. Participants in the competition compete in one of three categories: Creative Hour, Creative Calendar, or Creative Planet. Statistical methods were used to determine the number of participants by competition year, and to analyze the participants’ perspectives gathered through a questionnaire following the 2022 competition. The results of the statistical analysis indicate a growing trend in participation, accompanied by positive feedback from participants, particularly regarding the organization and the value of the experience. The discussion section of the paper assesses the organizational success of the large-scale event across all competition years. This assessment is based on two evaluations: the first focuses on attendance analysis and the second on analyzing participants’ perspectives. The conclusion offers insights into the characteristics of the largescale event as determined by the analysis, taking into account research limitations. Additionally, the conclusion offers recommendations for researchers and organizers of similar events with a reflection on the research characteristics. The advantages of this paper include a comprehensive approach to data analysis and the identification of key success factors of the event while the limitations are related to the limited availability of detailed data from previous years. This paper can be useful to organizers of large-scale competitive events, as well as researchers in the field of event organization.
