<![CDATA[Discipline is one of the problems commonly encountered in the field of education. Students with low levels of discipline significantly affect the learning process—not only do they struggle with time management, but they may also experience a decline in academic achievement, a lack of interest in learning, neglect of school assignments, poor time awareness, and reduced social interaction. This study aims to determine the effectiveness of group guidance services using self-management techniques to improve student discipline. The research employed a quantitative method with a pre-experimental design. The population and sample of this study consisted of Grade XI students at SMK Negeri 4 Pandeglang, who served as the experimental group. The experimental group received treatment in the form of group guidance using self-management techniques. Data collection techniques used in this study were questionnaires and documentation, while data analysis techniques included normality tests, homogeneity tests, and t-tests. The results showed a difference in the average pre-test and post-test scores after the treatment was given. Hypothesis testing using the t-test showed an Sig (2-tailed) value of 0.000 < 0.05. The intervention indicated a significant difference in discipline scores within the experimental group. Therefore, it can be concluded that group guidance using self-management techniques is effective in improving the discipline of Grade XI students at SMK Negeri 4 Pandeglang. Thus, the alternative hypothesis (H1) is accepted and the null hypothesis (Ho) is rejected.]]>
