This qualitative study examines "Trauma & the Brain"--a case-based training series for graduate-level social work students focused on the neurodevelopmental impact of childhood trauma. Four focus groups were conducted with 17 participants from the Trauma & the Brain training series. Reflexive thematic analysis identified six themes regarding students' application of training series content to their field work: nurturing a learning community, bridging content and curriculum gaps, understanding "the why," taking the toolbox into the field, confident communicators, and field challenges. Implications for social work education are discussed, including the necessity of preparing students for fluent communication about complex trauma in multidisciplinary settings, and building learning communities that connect students across cohorts and micro- and macro-practice tracks.
