Abstract Background: The Transformative Educational Advancement and Mentoring (TEAM) network is a program funded by the Center to Reduce Cancer Health Disparities (CRCHD) of the National Cancer Institute (NCI). In support of the NCI’s goal to reduce cancer health disparities, the CRCHD drives workforce diversity efforts by supporting trainees from backgrounds underrepresented (UR) in cancer biomedical and behavioral sciences research. The two TEAM programs launched at minority-serving institutions (MSIs) in 2023: The Southwest TEAM (STEAM) network and San Diego State University’s (SDSU) Advancing Cancer Careers for ExceLlence (ACCEL). Each program has a unique model designed to best serve trainees in their respective regions, but both provide: 1) Diverse Training Champions (TCs), role models and navigators who act as the primary point of contact for scholars, provide direct services to trainees, ascertain member needs, develop programmatic offerings, and connect trainees to program components; 2) a mentorship program for pre and postdoctoral scholars and early stage investigators (ESIs); 3) targeted recruitment and professional development of UR scholars; and 4) tailored linkages to professional development and employment opportunities, and NCI/CRCHD funding priorities. This work summarizes the strategies planned across both programs to promote recruitment and retention of investigators from UR backgrounds and cultivate professional development opportunities for students and ESIs. Approach: The STEAM network includes the University of New Mexico, New Mexico State University, Northern Arizona University, and Burrell College of Osteopathic Medicine and leverages the unique programs and expertise of these MSIs to collectively train diverse cancer health disparities researchers with interests in serving Native American, Hispanic and rural communities in the Southwestern United States. The ACCEL Program supports excellence, inclusion and transformation of the cancer research science force, expanding and strengthening the pipeline of UR scholars pursuing cancer research. SDSU, a Carnegie Foundation high activity research institution is one of few institutions to be both a Title Ill/Title V eligible institution for diversity. ACCEL works in close collaboration with the University of California San Diego Moores Cancer Center. We will discuss opportunities and approaches employed by each program in support of scholars to increase the number of diverse scholars in these research pipelines and demonstrate the effectiveness of such coordinated efforts. Conclusion: Supporting TCs to focus on scholars within regional programs will prove to be an efficient and effective way to increase recruitment and retention of diverse investigators in NCI research and community programs. Using novel strategies like TCs, the programs will support the attainment of career goals and enhance and diversify workforce capacity across the cancer research and care continuum.
