Steadily, more statistical data about student performance from international large-scale assessment studies becomes publicly
available. To facilitate access, the eduDWH project aimed at building a data warehouse integrating three such studies for
educational researchers. This target group is hard to access because it is not united through a single organizational context and
individual researchers are not stakeholders in the warehouse project. This paper proposes an adapted mix of focus group activities
and document analysis and reports about experiences while piloting these activities. It was found to be efficient for eliciting data
warehouse requirements even with limited direct target user contact.
