Impulsive behavior among students can hinder academic and practical achievements; therefore, this study aims to examine the effectiveness of group counseling services utilizing self-control techniques in reducing impulsive behavior among students at SMK Entrepreneur Al-Wasath Sesaot. This quantitative study employed a One-Group Pretest-Posttest design with nine students selected through purposive sampling. Primary data were collected using a validated Likert-scale questionnaire and subsequently analyzed using the Paired Sample t-Test. The results indicated a significant decrease in the mean impulsive behavior score, dropping from 31.78 at the pretest stage to 27.56 at the posttest stage. Statistical analysis yielded a calculated t-value of 3.555, which exceeded the t-table value of 2.306 (3.555 > 2.306), with a significance level of 0.007 (< 0.05). These findings confirm the acceptance of the alternative hypothesis (Ha), demonstrating that group counseling services using self-control techniques are empirically effective in reducing impulsive behavior among students.
