This study was motivated by the prevalence of truancy among students—manifested as arriving at school but failing to attend class, congregating in the canteen or restrooms with peers, or leaving the school premises without a valid reason. Such behavior is suspected to be linked to permissive parenting, characterized by excessive freedom, minimal supervision, and low expectations regarding student responsibility. The study aimed to describe the level of permissive parenting employed by parents, characterize student truancy behavior, and examine the relationship between permissive parenting and truancy. A quantitative method utilizing a descriptive-correlational approach was employed. The study population comprised all 953 students at SMA Adabiah 2 Padang during the 2026/2027 academic year; a sample of 60 students was selected using purposive sampling. Data were collected via permissive parenting and truancy behavior scales and subsequently analyzed using the Pearson Product Moment correlation test. The results indicated that permissive parenting generally fell into the "very high" category (30.00%), while student truancy behavior generally fell into the "high" category (41.67%). A correlation coefficient of 0.557 with a significance level of 0.000 (p < 0.05) revealed a moderate positive relationship, indicating that higher levels of permissive parenting are associated with a greater tendency toward truancy. It is concluded that there is a significant relationship between permissive parenting and student truancy at SMA Adabiah 2 Padang. These findings highlight the importance of school guidance and counseling services—specifically through information sessions on discipline and the impact of truancy on academic and personal development, as well as group guidance and individual counseling for students exhibiting tendencies toward truancy. Furthermore, collaboration among guidance counselors, homeroom teachers, subject teachers, school authorities, and parents is crucial for more effectively monitoring, preventing, and addressing student truancy.
