Introduction: Suicidal behavior is a growing public health concern worldwide. The educational contexts stand out as one of the most prominent environments for working with adolescents, both in promoting emotional well-being and in preventing mental health issues. This work aims to examine the prevalence of suicidal behavior among students within the framework of the PSICE study and emphasize the importance of addressing this issue in educational settings. Method: The sample consisted of 2235 students aged 12 to 18 from the Autonomous Community of La Rioja (46.8% males). A total of 34 educational centers and 98 classrooms participated. The instrument used to assess the risk of suicidal behavior was the SENTIA-Brief Scale of Suicidal Behavior in Adolescents. Results: 3.2% of the sample responded affirmatively to having attempted to take their own life. In all cases, females showed a higher proportion of affirmative responses compared to males. Overall, 3.9% of the sample would be classified as having a high severity level. Conclusions: The high prevalence of suicidal behavior among students underscores the importance of implementing prevention and support programs in the educational setting. Collaborative efforts between psychology professionals and educational professionals can make a difference in the lives of students. This study emphasizes the need to continue researching and developing effective strategies to address suicidal behavior in educational contexts.
