School counseling of students and parents as well as the role of the school counselor are becoming increasingly imperative in schools, especially in high schools, due to the fact that adolescents face more and more challenges in what is already a challenging and particularly sensitive period for them and their parents. In the national context, there is more and more research on the topic of school counseling, but the phenomenon has mostly been investigated as part of student research papers. The aim of this study is to describe and understand the experiences of school counselors in counseling high school students and their parents. In the first part of this paper, the theoretical foundation is presented and basic constructs such as adolescence, cooperation between parents and school and school counseling are defined. As a part of this, the results of previous research on the topic are also presented. For the purposes of this qualitative research, a (semi-structured) interview protocol was created that was used in conducting interviews with five female school counselors employed in vocational schools in the cities of Rijeka and Opatija. The questions in the protocol are designed so that the data and information obtained by the participants provide answers to specific research questions related to problems that require school counseling with high school students and their parents, the process of school counseling, the way in which the school counselors achieve cooperation with high school students and their parents in the process and the factors that influence the satisfaction of school counselors when conducting counseling. The results indicate that the overall experience of school counselors in counseling high school students and their parents is described as positive, and its importance is emphasized because there are many and various problems that require its daily implementation. Furthermore, school counseling and individual counseling conversations are described as unique due to the individual and specific situations of each student, while the cooperation that school counselors achieve with parents and high school students is described as positive. The cooperation is also achieved outside of counseling, through various formal and informal instances of working with high school students and their parents. In addition to certain challenges that school counselors cite when conducting school counseling, there are also numerous other factors that influence their satisfaction with it, and the most prominent are those related to the participants themselves and those related to the school counselors’ competencies for its implementation. Considering everything that has been said, it can be seen that the need to continue studying the topic of school counselling perseveres, especially in the area of issues related to ethical principles in the work.
