From Practitioner to Scholar: A Collaborative Autoethnography of PhD Students' Research on Evaluation Journeys

open access: yesNew Directions for Evaluation, Volume 2025, Issue 187, Page 67-82, Fall 2025.
ABSTRACT There has been limited attention to the role of research on evaluation (RoE) in PhD‐level evaluator education. Previous research suggests that evaluator education doctoral programs have multiple purposes to prepare practitioners and researchers, thus creating an unnamed tension where evaluation practice is the focus and RoE has not been ...
