100% FTE or 1.0 FTE refers to one full-time employee or a number of people who make up the duties of one full-time position. If an organization considers full-time to be a 40-hour working week then one full-time employee will count as 100% FTE. 100% FTE can also be achieved in several other ways, for example, through two part-time employees (who each work 20 hours per week) or four employees who work 10 hours per week.
