For the concept of competence, there are various definitions and many scientific and professional works dealing with this issue. In this research, we used the definition of competence from the Oxford dictionary in 2003. "Competence is explained as: having the necessary knowledge and ability to do something successfully and as a set of related knowledge, attitudes, skills and other personal characteristics that affect the main part of one's job". Also, in this paper, we will base ourselves on the concept of awareness, which represents a psychological function. Due to the insufficient competences of movement in water, many people drown, and the goal was to see how many people of different professions are aware of this problem. Competences for movement in water include: jumping into water, immersing the head in water, breathing and breathing control below and above the surface of the water, rotation of the body around the longitudinal, transverse and sagittal axes in the horizontal and vertical position of the body on the water. The aim of this research is to gain an insight into the level of awareness of the importance of the competences of movement in water. An effort will be made to obtain data on how the respondents of different populations influence the general awareness of the importance of the competences of movement in the water in order to present the possible factors that influence such attitudes. It will also be determined whether there is a difference between the respondents with regard to the different occupation profession. The subjects of this research were first- and second-year students of the University of Zagreb's Faculty of Kinesiology (127 respondents), second-year students of the University of Zagreb's Faculty of Economics (188 respondents), and teachers of classroom and subject classes in elementary schools in Zagreb and Rijeka (76 respondents). The research was conducted through a questionnaire using a Likert scale of agreement or disagreement through 22 statements. The collected data were processed in the statistical data processing program Statistica. The basic statistical indicators obtained on the frequency of responses for collective and separate variables were calculated with analysis of variance (ANOVA) and Student t- test for indenpendent variable. The results of descriptive statistics show that the highest results were recorded in claim number 12 (mean=4.51), and the lowest in claim number 18 (mean=2.34). According to the results of the Student's t-test, the subjects of the Faculty of Kinesiology in Zagreb showed the greatest statistically significant difference compared to the subjects of the Faculty of Economics in Zagreb and Professors in statement number 2. Given that the competencies of movement in water are very important in the prevention of drowning, it is extremely important to arouse awareness of the general population about this problem and find ways to educate parents, adolescents, children and adults. This research also mentions professors who have an exceptional role in raising and educating children, and their attitude about the importance of knowledge of movement in water is important.
