Average tenure of employees of the organization as of the end of the reporting period.
Organizations should footnote all assumptions used. See usage guidance for further information.
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.
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
