In this article, we first analyze the situation of statistics education in Brazil, within an international context of interest for this discipline. Secondly, we aim to answer the following research question: How has doctoral research in statistics, probability, and combinatorics education evolved in Brazil? For this purpose, we analyzed the Brazilian doctoral research production from 1994 to 2021. We identified 102 completed dissertations in doctoral programs over the last 28 years. Within this research context, we analyzed the graduate programs, advisors, research themes, grade levels and participants studied, theoretical frameworks, and the data analysis methodologies employed. Even though doctoral research has developed slowly and irregularly, there has been an increase in the number of studies, driven by the growth of graduate degrees offered in the last few years.
