National Health Service Corps (NHSC) Full Time Equivalent (FTE) – NHSC health professionals can be assigned to one or more sites. Each provider spends a certain amount of time at a site, and their involvement at a site is measured in Full Time Equivalents (FTE). An FTE is the amount of time that a provider is working at a particular site relative to a full-time schedule of 40 hours per week. If a provider is working 40 hours per week at a site then the FTE value for that provider is 1.00, and if a provider is working 20 hours per week at a site then the FTE value for that provider is 0.50. If a provider is working more than 40 hours per week at one or more sites they will still be counted as a maximum of 1.00 FTE. In these scenarios, the FTE calculation per site will be based on percentage of time spent at each site. For example, if a provider is working 30 hours at one site and 20 hours at another they will be considered 0.60 FTE at one site and 0.40 at the other. NHSC participants serve in NHSC-approved sites designated by HRSA as being in a HPSA.
