Adolescence is characterized by a multitude of challenges, namely ones concerning mental health and wellness. To address this problem, many schools have implemented mental health programs based on campus. While the progress of school-based mental health programs has been explored and documented, there is a gap in the literature about the audience, modality, and satisfaction of these services. The purpose of this study is to assess the use of a Tier 1 approach, its impact on high school participants, and receptivity to the program. For this survey study, archival data from post-treatment surveys were used to explore students' attitudes toward the program and its perceived usefulness. Quantitative data was also used to investigate any gender differences in responses across participants. Findings indicate that most students practiced mindfulness weekly and found that it helped reduce stress levels. Analyses also revealed what students liked most and least about the 12-week mindfulness program. Implications for future school-based Tier 1 mental health interventions are discussed.
