Minding the gap: Evidence, implementation and funding gaps in mental health services delivery for school-aged children.

State and local educational agencies are grappling with growing mental health needs among school-aged children that intensified during the COVID-19 pandemic. We undertake a case study of the experiences of one state, Tennessee, to examine the landscape of mental health interventions that are being deployed and to illuminate contextual factors that can support their implementation or exacerbate state and local challenges in addressing children's fast-rising mental health needs. We begin with an examination of the knowledge base on interventions and approaches that are commonly employed in K-12 schools to address children's mental health needs, including in Tennessee, with the aim to identify notable gaps in what we understand about their implementation and impacts on student outcomes.
