Studies exploring patient experience with eating disorder specialists have reported poor gender competency among clinicians, as revealed through patient-clinician interactions. Through interviews with eating disorder specialists, the authors sought to (1) clarify how and why current practice and clinical training may not meet the needs of transgender and gender-diverse patients, (2) assess where and how clinicians received education on gender identity, and (3) how changes can be made to meet educational and patient needs. Specialists were recruited, and semi-structured interviews were conducted. Narratives were coded by two independent coders, using thematic analysis. Four key themes emerged from 19 completed interviews: Training and education received, importance of receiving training or education, self-education, and improvements recommended by clinicians. Only ~ 16% (n = 3) of clinicians reported sufficient training both in graduate school and through their place of employment. Most with sufficient education received it at their clinic/practice. Despite lacking formal training, all clinicians engaged in some form of self-education on gender. These findings support the need for standardized and comprehensive graduate curricula, in-service training, and continuing education requirements. Advocacy is required to encourage accrediting organizations to mandate training on gender among mental health clinicians.
