Objective: this study aims to analyze and characterize the movement of expansion of Nursing undergraduate courses in Brazil since the 1990s. The characteristics of this expansion are discussed, as well as the socio-political setting where such movement occurred, and the quality of education available based on the data collected. Method: this is a descriptive and cross-sectional study with a quali-quantitative approach, with the use of secondary databases. Results: an accelerated and disordered growth of Nursing undergraduate courses was identified, as well as the number of vacancies, especially due to the participation of the private sector, especially since the year 2000. Geographical inequalities in the distribution of these courses and vacancies were also identified. Conclusion: the strong expansion of higher education in Nursing, along with other health professions, resulted in the strengthening of private higher education institutions associated with economic groups, regional concentration, as well as the excessive offer of distance learning without adequate evaluation of its quality or repercussions.
