This research is a descriptive study in the relational screening model that aims to examine the relationship between the career adaptability levels and attachment styles of high school students. The study group consists of a total of 582 students, 362 girls and 220 boys, who are attending the 9th, 10th, 11th and 12th grades in 4 high schools in the central districts of Adana. The age range of the participants is between 14 and 19 years old. In the study, data on the career adaptability of adolescent students were obtained by using the 'Career Adaptability Skills Scale,' the data on attachment styles were obtained by using the 'Relationship Scales Questionnaire,' and the data on personal information were obtained by using the 'Personal Information Form' prepared by the researcher. In the analysis of the data of the study, Pearson Correlation Coefficient, t-test, analysis of variance and standard multiple regression analysis techniques were used. According to the results of the research, while there was a significant relationship between career adaptability abilities and secure, fearful and obsessive attachment, it was seen that there was no relationship with indifferent attachment. When the results of multiple regression analysis are examined, it is seen that attachment scale sub-dimensions are a significant predictor of career adapt-abilities. The only predictor of high school students' career adapt-abilities is secure attachment. Other variables were found to be meaningless.
