The article presents the first part of an Unimonserrate inter-school research: "Formulation of the Catholic School Teaching Project, from the SEAB experience (Archdiocese of Bogota Educative System). Proposal based on the relationship among teachers' educational practices at different levels of education and the expansion of human capabilities in students". It explores thefoundations and generalities of the Catholic School, the role of the teacher, and the central human capabilities approach proposed by Martha Nussbaum. As the result of this exploration, points in common that allow us to understand the work of the Catholic School from the perspective of the Human Capabilities Approach are presented, which constitute the initial categories of analysis for the development of research.
