Anxiety and depression symptoms are becoming more and more common in adolescents with the majority of them not seeking treatment. Cognitive behavior therapy can be a successful treatment of their symptoms when implemented and used accurately. Not all school districts offer mental health services through an outside mental health agency. This mixed-methods case study examined school-based mental health services in three local school districts. Through a questionnaire-design and follow-up interviews, the benefits and barriers to students receiving therapy through a school-based mental health program in high school are identified from the perceptions of high school teachers and high school graduates. The benefits included the ease of access to the service, the students receiving the help they need, and the lessening of the symptoms of mental illness, while the barriers included the service being stigmatizing and student family issues. These findings can help support both school districts and mental health agencies as recommendations for both are provided along with recommendations for further research.
