Since 1997, the Resource Centers for Minority Aging Research (RCMAR) program, supported by the Division of Behavioral and Social Research (BSR) at the National Institute on Aging, has served as BSR's flagship mentoring program for early-career scientists from diverse backgrounds. Over the years, it has undergone significant changes to address evolving institutional priorities and societal needs. This article highlights the motivations behind programmatic shifts in the fifth funding cycle (2018-2023) and the guiding principles for RCMAR VI (2023-present). Key developments in RCMAR V included the launch of RCMARs focused on Alzheimer's disease (AD) and Alzheimer's disease-related dementias (ADRD), a refined emphasis on behavioral and social research, and the decoupling of workforce diversity from health disparities research. Building on lessons learned from the prior funding cycle-amid challenges posed by the coronavirus disease 2019 pandemic and leadership transitions-RCMAR VI offers enriched research, training, and mentorship opportunities while introducing equitable governance structures and clearer, broader expectations for success. The new RCMAR National Coordinating Center plays a crucial role in fostering collaboration, standardizing evaluation, and leading activities to broaden the program's impact. With a renewed focus on high-priority behavioral and social research on aging, AD/ADRD, and health disparities, RCMAR VI is poised to diversify the scientific workforce and advance discoveries.
