There's an increase in mental health concerns with youth, making it imperative to address developing educators' capacity for identifying and delivering mental health supports. Youth Mental Health First Aid (Y-MHFA) aims to provide the tools for adults to offer aid to youth in need or in crisis. This review examined outcomes associated with Y-MHFA when implemented in school settings. Eight relevant studies were identified through a comprehensive systematic review of online databases, such as PsychINFO and ERIC, and related references. Published studies specifically about Y-MHFA written in English that report educator and/or college student outcomes were included. Overall, findings from the review illustrate promising gains in youth mental health literacy in educators and college students. However, there was a lack of control groups, long-term follow-ups, and cultural and diverse considerations to fully support Y-MHFA. Mental health awareness, strategies, and skills gained after Y-MHFA have implications for educators providing mental health supports to adolescent students and, therefore, increasing future student success. Further implications and areas for future research are discussed.
