Usage Guidance
-
This metric is intended to capture the average length of time individuals in permanent employment are employed by the organization. Organizations should exclude Temporary Employees (OI9028) from this calculation. To calculate tenure, subtract an employee’s (employment) start date from the earlier of the end date of the reporting period or their termination date during the reporting period. Sum the total number of days across all employees and then average as shown in the calculation. Where applicable, footnote the type of date used as an employment start date in the tenure calculation, such as “immediately upon employment” or “upon satisfactory completion of a probationary period.”
-
In addition to calculation assumptions, organizations are encouraged to footnote any narrative regarding average employee tenure.
-
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 IRIS+ and the Five Dimensions of Impact (https://iris.thegiin.org/document/iris-and-the-five-dimensions/). 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.

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).
