Purpose: The purpose of this paper is to conduct a quantitative analysis of the university accreditation processes in Chilean universities. The aim is to determine the effects of the different variables, especially the type of institutions (state- and privately owned, with and without state financial support) on the results obtained. Design/Methodology/Approach: Univariate and multivariate statistical analysis of official data. Findings: Results indicate consistency in the accreditation processes in Chilean universities, as those variables directly associated with the processes accounted for approximately 70 per cent of the variation in the length of accreditation periods (between 0 and seven years), these variables being the ones that defined the type of universities. High dispersion was found in six state-owned universities that behaved as if they were private universities and in two private universities that behaved as if they were state universities. However, a high percentage of the universities included in the analysis maintained their affiliation to their corresponding legal group, when their performance in accreditation processes was analyzed. Originality/Value: The results of the university accreditation processes in Chile have been the focus of a intense debate due to the legal and economic conflicts between the different types of universities. This study constitutes the first scientific analysis of the results of these processes, especially in terms of the performance of the different types of universities, thus enabling a better interpretation of the results. This information is useful not only in the terms of the legal reforms that are being carried out in Chile, but they also help the understanding of the processes of accreditation of higher education in other Latin American countries.
