Teenagers of high school age have a high risk to commit various juvenile delinquencies. The ability to control themselves is crucially important to develop by assisting and guiding them both individually and in a group to prevent them from various risky behaviors. The study aimed to determine the effect of transpersonal counseling on high school students with self-control issues. The research was a quantitative study with a quasi-experimental design that utilized data collection tools of self-control scales and academic cheating scales. The selfcontrol scale reliability test was conducted using the Cronbach Alpha formula and received a value of 0.803. The samples in the study were 12 students in the eleventh-grade students out of a total population of 360 students. Data was collected using a questionnaire and were analyzed using the t-Test to find the difference between pre-treatment and post-treatment of transpersonal counseling intervention. The results of this study indicated that 8 out of 12 students showed a significant increase in the self-control after treatment. The average score for the pre-treatment was 8.85 and increased to 11.34 after counseling. It is expected that the finding can be used as a reference for Guidance and Counseling teachers in developing transpersonal counseling services for students with self-control issues.
