This study identifies the assets that principals use to support school based mental health care [SBMH] and makes several recommendations for increasing the efficacy of principals in interacting with SBMH systems and includes their recommendations for improvement in fostering, sustaining, and improving SBMH. Mental health needs are a historically underserved issue that greatly affects the ability of students to learn and flourish. Through a grounded theory analysis within a multiple case study framework, five cases are described and thereafter nine assets were developed as common to the cases informing on the beliefs, competencies, and traits possessed by principals. The identification of these nine assets supports emergent findings of a construct of interactions and describes common factors involved in a principal's support of SBMH.
