Drawing upon an ongoing school mental health survey being conducted in California, this article examines associations between high school students' mental wellness, including covitality (as measured with the Social Emotional Health Survey--Secondary), and school safety perceptions and experiences. Student self-reports reveal a strong positive association between psychosocial wellness and feeling safe and secure at school. Proactive efforts by educators to foster students' thriving well-being could also have the benefit of improving school climate and safety.
