Currently, public universities in Peru are undergoing changes due to new market requirements, aspects that regulatory entities took into account to rethink their operational requirements, therefore, it is necessary that their processes are adapted and comply with these new characteristics regulated according to law, especially academics who relate directly to teachers and students, these processes must be transformed taking into account emerging technologies. To solve this problem, a sustainable digital transformation model was developed, consisting of four dimensions: infrastructure, business architecture, digitalization, and people. In each dimension, indicators were used to assess at what stage of maturity it is found, which by integrating them allowed us to know the level of general maturity of the digital transformation of the institution in which our case study was applied to the effects of knowing the digital divide. This model was validated in a national university of Peru, specifically in the process of managing the digital teaching portfolio.
