National Health Service Corps The National Health Service Corps (NHSC) helps bring health care to the most vulnerable and underserved populations, by placing health care professionals in designated areas of need. The NHSC builds healthy communities by connecting primary health care providers to areas with limited access to medical care. This is achieved by awarding scholarships and loan repayment to primary care providers in NHSC disciplines (medical, dental, and mental health) who commit to serving at NHSC-approved sites in these areas of need. The HRSA Data Warehouse (HDW) allows users to interact with data in charts, tables/reports, maps, and tools. Visit the Data Sources and Refresh Dates page for more information about where NHSC data is available in the HDW. These data sets include NHSC Job Opportunities, NHSC Providers, and approved NHSC sites.
