Prior studies have shown that socially accepted students tend to be more focused on learning and achieve better academic outcomes, and social acceptance plays a key role in students' psychological well-being. Social acceptance among students significantly impacts their academic success. When students feel accepted and included in the school environment, they show greater motivation to learn and achieve better results. This highlights the importance of creating an inclusive school environment where every student feels welcome and supported. The research of social acceptance of vulnerable groups of students in the peer group was conducted using sociometry among fifth graders in Slovenia. We found out that most fifth-grade students fall into the group with an average sociometric status. Additionally, students from vulnerable groups predominantly have either medium or low sociometric status. However, the assumption that students from vulnerable groups would primarily fall into rejected or neglected sociometric categories was not confirmed, as they occupied various sociometric positions. Understanding the group with average sociometric status is essential for supporting social acceptance and improving academic achievement. Programs and interventions tailored to this group could help enhance their social skills and school integration. Further research is needed to promote social acceptance, foster collaboration between schools, parents, and education experts, and raise teachers' awareness of the importance of social inclusion in the classroom. These efforts can contribute to a more inclusive school environment, benefiting students' academic success and long-term well-being.
