Organizational evaluation policies describe how evaluation practices should be structured and implemented. As such, they provide key insights into organizational priorities and values regarding evaluation. However, the link between evaluation policies and how evaluation policies translate into concrete practices has seldom been explored until now. Our study examines the implementation of two Canadian federal government evaluation policies over a 10-year timespan, through the secondary analysis of reports produced on behalf of governmental evaluation functions. Our findings show that some policy elements have been fully implemented, but the way in which these have been implemented varies between organizations. Further, we observed that the level of control of various organizational members responsible for implementing policy elements, as well as time, can influence implementation of certain policy requirements. We conclude by proposing further directions for research to examine the policy-practice link.
