This study aimed to examine the effect of career anxiety on high school students' career decision-making. The study group of the research consists of a total of 449 students, 146 boys (32.5%) and 303 girls (67%), who continue their education in different high schools in Konya center and districts. Research data was obtained using the "Personal Information Form" prepared by the researchers, the "Career Anxiety Scale" developed by Çetin-Gündüz and Nalbantoğlu-Yılmaz (2016) and the "Vocational Decision Making Inventory" developed by Çakır (2004). A relational screening model based on a descriptive method was used in the research. In the analysis of the data, parametric statistical techniques such as t test, one-way analysis of variance (ANOVA), Tukey test, correlation and regression analysis techniques were used according to the normality test. According to the research findings, there is a significant relationship between both career anxiety regarding family influence and career anxiety regarding career choice and all sub-dimensions of career decision-making. In addition, there is a low level positive relationship between students' career concerns related to family influence and the sub-dimensions of internal conflicts, not knowing oneself well enough, lack of profession and field knowledge, and irrational beliefs about career choice, and a moderate positive relationship between the students' career concerns and the external conflicts sub-dimension.
