Professional Doctorates (PD) as a model of doctoral training, parallel to and independent from the traditional Academic Doctorates, began to expand throughout the 1990s in countries of the Anglo-Saxon world, echoing timidly in Ibero-American countries. This article carried out a comparative study between the PDs of Brazil and Mexico, the only countries in the Ibero-American region that have created PDs in their educational systems, aiming to analyze their convergences, divergences, and specificities. This is an exploratory, analytic-descriptive, bibliographic, and documental study. Among other important findings, it is noteworthy that unlike the Mexican norms that relate PD specifically to the professional development of doctoral students, in Brazil there is a broader, prevailing conception aimed at increasing the productivity of companies and public and private organizations, technology transfer and the production of innovative knowledge.
