Change-projects can be evaluated in different ways. One of the ways is to evaluate with process thinking, which means that evaluators are involved in the process from the very beginning. Involvement of evaluators already in the beginning of a project can mean several challenges for both the project itself and the evaluators. This study is about describing and analyzing how and with what results the perspective of process thinking on evaluation of the national learning project Care on equal terms was used. The results indicate, among other things, that it was a good choice to bring in evaluation perspective at the beginning of the project. Process thinking has, among other things, contributed to the activities throughout the project, and played a role in learning from and implementation of the project itself.
