All over the world, the quality of healthcare remains problematic due to inadequate funding, inadequate physical facilities, insufficient service delivery, waiting lists, differences in the healthcare providers' abilities, a low understanding of team members' roles, and miscommunication. For those problems, there are different tools and models for improvement. This study aimed to study postgraduate students' experiences regarding healthcare quality. A qualitative descriptive-phenomenological study on 24 postgraduate students recruited judgmentally who have bachelor's or master's degrees and are registered for master's or doctorate degrees from different specialties. Study results revealed that 75.0% of the postgraduate students were nurses, and all had bachelor's degrees. Furthermore, only 16.7% of them attended theoretical courses about healthcare quality. Moreover, postgraduate students expressed limited experience regarding parameters, dimensions, tools, and models related to healthcare quality. The researchers conclude that postgraduate students' experiences regarding quality of care, healthcare quality parameters, quality of care dimensions, tools for improving the quality of care, and quality improvement models are not contextualized. The researchers recommend conducting on-the-job education and training for healthcare professionals concerning healthcare quality.
