The purpose of this research was to analyse the relationship development and communication competence of MPhil/PhD supervisors. A confirmatory mixed-methods research design was used to conduct the study in two stages. For both phases, 360 MPhil/PhD graduates and 72 supervisors were selected from four public universities in Punjab using a multistage sampling technique. Data were collected electronically from 239 MPhil/PhD graduates during phase-I using an adapted questionnaire from ASHA's supervision model, while in phase-II, 72 MPhil/PhD supervisors were interviewed to cross-check the Phase-I findings. According to MPhil/PhD graduates, their supervisors have relationship development and communication competence. During interviews, most MPhil/PhD supervisors refute their supervisees' claims and offer suggestions to improve supervisors' competence. Based on supervisor suggestions, the Higher Education Commission of Pakistan should revise the supervision structure, provide Postdoctoral fellowships to all supervisors, and promote international conferences. This study may be helpful to supervisors in self-evaluation as well as understanding relationship development and communication competence.
