Discipline is an important aspect of vocational education because it is closely related to the formation of responsibility, compliance with rules, and students’ readiness to enter the world of work. However, preliminary observations indicated that five Grade X TAB students at SMK Negeri 1 Palangka Raya had low levels of discipline, as reflected in behaviors such as arriving late, failing to wear complete school uniforms and attributes, skipping classes, being frequently absent without explanation, and paying insufficient attention during classroom learning. This study aimed to examine the effectiveness of group counseling using the Behavior Contract technique in improving students’ discipline. This research employed a quantitative approach with a preexperimental one group pretest posttest design. The population of the study consisted of Grade X students at SMK Negeri 1 Palangka Raya, while the sample comprised five Grade X TAB students selected through purposive sampling based on observations, interviews, and criteria indicating low discipline. Data were collected using a student discipline questionnaire and analyzed using a paired sample t test. The findings showed that the students’ mean discipline score increased from 44.60 in the pretest, which was categorized as low, to 69.80 in the posttest, which was categorized as moderate, after receiving group counseling using the Behavior Contract technique. The statistical test showed a significance value of Sig. two tailed = 0.000 < 0.05, indicating a significant difference between students’ discipline scores before and after the intervention. These findings suggest that group counseling using the Behavior Contract technique can be used as an alternative strategy to help vocational high school students improve discipline through behavioral agreements, strengthened responsibility, and group support. Nevertheless, the findings should be interpreted cautiously because the sample size was limited and the study did not include a control group.
