PhD students should not be solely judged by the number of journal articles they have produced. While publications are a critical measure of a PhD's productivity and contribution to their field, they are not the only indicator of success or ability.
PhD students should be evaluated on the quality of their work, their critical thinking skills, their ability to solve problems, and their contribution to their discipline in general. These factors can be considered in evaluating their contributions, whether or not these contributions are made in the form of publications.
Additionally, many doctoral students face challenges such as funding, access to data, and time constraints that may limit their ability to produce journal articles. These limitations can result in the prioritization of other modes of scholarship such as conference opportunities, poster presentations, patent applications, data sharing, and policy briefs, which are equally valuable.
Ultimately, the doctoral process and its evaluation should be viewed as a holistic process with an emphasis on professional development, creation of new knowledge, and producing work of high quality across a range of relevant platforms.
