In Canada, formal structures for advancing engineering education research (EER), including graduate programmes, funding, and career pathways, are uncommon. However, an active informal EER community exists. Using the Identity Trajectory Framework, we designed an exploratory basic interpretive qualitative study to learn how 21 graduate students experienced EER in Canada. EER's dualist internal identity and lack of external identity, credibility, and structural support create a feedback loop of uncertainties for graduate students trying to navigate EER. This inhibits the healthy development of EER as an academic discipline, and thereby, the healthy development of EER graduate students. If we want to successfully support graduate students in developing their identity as EER researchers, we need institutional structures. Understanding how graduate students experience EER in Canada is important to understand how to build capacity here and in other locales where the field is newly developing.
