The research study aimed to identify the defining characteristics of a great Filipino nurse educator which have provided input in developing a theoretical model of a great Filipino nurse educator. This research is a qualitative study which employed a grounded theory methodology toward theory development. The following findings generated 26 categories and 9 themes from the responses of 53 nursing students and professionals. Findings revealed that the great Filipino nurse educator is defined to be a world-class (World-Klas) nurse educator who is highly qualified (Kwalipikado) from having education, experience, physical and mental fitness and being a lifelong learner. He is competent (Natatanging Kakayahan) in teaching, leadership and managerial roles, and engages in research and accreditation. He possesses caring (Mapagmahal) behaviors that are shown through communication, passion, compassion, commitment, inspiration and empowerment, transcendence, nurturing and belief in his student’s capabilities. She is equipped with well-rounded personality (Mabuting Pagkatao) comprising of positive traits, versatility, resilience and sense of humor. She is spiritual (Maka-Diyos), patriotic (Maka-Bayan), a role-model (Idolo) and catalyst agent (Tagasulong ng Pagbabago). The road to greatness of a Filipino nurse educator is all attuned with the strongest core of being spiritual and patriotic that makes it very Filipino which demarcates a great Filipino nurse educator from what is not. Each characteristic is significant because all are important in describing what a great Filipino nurse educator is. One characteristic cannot be absent nor removed for it will not decipher the puzzle of what completes the defining characteristics of a great Filipino nurse educator. Total greatness is not an end product;it is an ongoing, deliberative process. Teacher’s greatness is a lifelong pursuit. Greatness is the result of many factors.
