This research focuses on the continuing education of primary and secondary school teachers by way of a Master`s degree for the sake of personal, professional, and institutional advancement. It seeks, therefore, to investigate the relationship between university and school; to verify whether this level of study indeed brings university and school closer together by meeting the school teacher`s expectations and helping them in their personal and professional development-besides improving the quality of the institution where they serve. The investigation took place at a public school where most teachers return to the same institution-whether working part-time or full-time- after finishing their Master`s degree. In this qualitative research, I used semi-structured, testimonial-type interviews as a main tool. Both primary and secondary school teachers and administrators were interviewed. In analyzing the answers to my guided open-ended questions, I sought to clarify what this kind of degree means to the primary and secondary school teacher and his/her profession, also defining its importance to the school`s improvement. Almost one-third of the primary and secondary school teachers who work at the school branch under study have a Master`s degree, and there are many others pursuing the same kind of post-baccalaureat education-the very same picture we encounter when considering all the branches together. There are many authors who, likewise, seek to investigate the continuing education of primary and secondary school teachers and their social and professional development, such as Nóvoa, Lüdke, Dubar, Beillerot, André, Candau and Contreras, among others. The analysis of this research, incorporating the line of thinking of the aforementioned authors, indicates that a Master`s degree in this kind of context represents an important investment for the primary and secondary school teacher both personally and professionally in his/her teaching experience. It is an important degree because of its focus on research and the depth of the very thesis a teacher must develop in a graduate level. At last, the Master`s degree is a possible and favorable path for reflection, besides enhancing both the faculty endeavors and the institution where they serve.
