Average Employee Tenure (OI2248)

This metric measures the average length of time individuals are employed by the organization. To calculate tenure, subtract an employee's (employment) start date from the current date or termination date when employee has departed and calculate the average for all employees. Where applicable, footnote the date used as a start date for the tenure calculation such as: immediately upon employment, upon satisfactory completion of a probation period, etc.

This calculation should only include figures for employees still remaining at the organization as of the end of the reporting period (i.e., should exclude figures for employees that departed during the reporting period).

In addition to calculation assumptions, organizations are encouraged to footnote any narrative regarding the average employee tenure figure.

In some contexts, this metric can be used to measure the duration that a specific outcome lasts for. In those cases, this metric may serve as an indicator for the HOW MUCH Duration dimension of impact. For more on the alignment of IRIS metrics to the five dimensions of impact, see specific guidance document. No single metric is sufficient to understand an impact; rather, metrics are selected as a set across all dimensions of impact. When possible, the selection of metrics to measure and describe the five dimensions should be based on best practice and evidence.
