Previous research has shown that students transition from high school to university can lead to different levels of stress. However, there is no consensus of how the students’ stress levels develops throughout the years they study at a university. Therefore, the purpose of this study was to examine if there was a diffence in perceived stress between first year, second year, and third year students at a university in Sweden. A quantitative approach was applied, where the data was gathered through the Perceived Stress Scale 14 that was supplemeted with a selfconstructed self-rating scale and demographic questions. A total of 126 students participated in the survey where 41 were first-year students, 41 were second-year students, and 44 were third-year students. The empirical data was analyzed with the help of Karasek and Theorell’s (1990) job demand-controlsupport model and previous research. The result showed that there was no significant difference in perceived stress between the students in the different study-years, however, all students’ experienced a high level of stress.
