To examine the extent to which the AIDS Education and Training Centers (AETCs) are increasing the number and racial/ethnic diversity of HIV medical providers, in accordance with the US National HIV/AIDS Strategy (NHAS).We used administrative data from funding year 2012-2013 to describe AETC trainee characteristics, including the types of medical providers trained, compared with national estimates of available US medical providers to estimate the proportion of providers trained for every 1000 available providers by professional group and race/ethnicity.AETCs trained 56 127 unique trainees, of whom 64.1% were medical providers and 45.5% were racial/ethnic minorities. Compared to national proportions, participation in AETC training was higher among racial/ethnic minorities. The proportions of racial/ethnic minority groups trained differed across regional AETCs.AETCs support NHAS goals by expanding the HIV medical workforce and strengthening the skills of minority medical providers to deliver high quality HIV care. Public Health Implications. Some AETCs made greater contributions to training different types of racial/ethnic minorities, which indicates varied approaches are needed to best target these efforts in communities heavily impacted by HIV.
