This study aimed to investigate the adjustment process of the youth who quit vocational high school. For this study, the base data of 16 adolescent who left vocational high school over a year and didn`t return to school was collected and Grounded theory approach was used to analyze. The result showed that dropouts experienced ‘anxiety’, causal conditions were ‘career maturity’, ‘achievement’, ‘trauma’ and contextual conditions of the phenomenon were ‘willpower’, ‘psychological stability’ and ‘inclination’. Also, Intervening conditions were ‘support system utilization’ and ‘motivation’, the action/interaction strategies for controlling phenomenon were ‘to challenge’, ‘to escape’ and ‘not to try’. Finally, ‘being developed’ and ‘being unsettled’ were observed as the consequence of the phenomenon. As the youth passed through indulgence stage, consciousness stage, trying change stage, and reestablishment stage, their adjustment process is increased. On the other hand, the youth stayed with status quo when they couldn't respond appropriately. The core category was ‘overcoming anxiety and finding identity’ and goal pursuit, transition, lethargy and escape types were showed as the following from the core category. This study gave an idea not only that process of development is needed to understand and approach the youth`s adjustment process, but also provided basis data that could help in increasing level of them.
