Self-concept is important for individuals because individuals can view themselves and their world, influencing not only individual behavior but also the level of satisfaction obtained in their lives.  The aim is to improve self-concept in SMK students through effective group guidance services. The subjects of this study were 10 SMK students with low self-concepts using purposive sampling. There is also a variable studied self-concept. The method used in this study is a psychological scale. In contrast, the data collection tool used is a self-concept scale, the initial stage of which is tested for validity and reliability. As for the results of the validity test N = 30, r table 0.361, the instrument used is valid because r count > r table. While the reliability test with the alpha formula can be seen as r count = 0.889 > 0.361, it can be said that this instrument is reliable. The data analysis technique used is a non-parametric method using the Wilcoxon test. From the results of research conducted at SMK, it can be concluded that based on the research results, self-concept can be improved through group guidance services. The Wilcoxon test results obtained Zcount = -15.860, which is less than Ztable = (-0.48) or is in ​​Ho rejection. This shows a significant increase in self-concept after participating in group guidance services.
