The general purpose of this research was to explain the relationships between the latent and observable variables of an e-learning system aimed at improving students' academic performance, by integrating the ISSM and TAM models in the sustainable electronic learning process, using classical PLS-SEM, CB-SEM, and Bayesian B-SEM structural equation modeling approaches. The data were collected from a survey directed at students in the 2023-II academic cycle of the National Agrarian University La Molina (UNALM). The instrument considered 40 items and used a Likert scale from 1 to 5. The questionnaire obtained acceptable reliability values and content validity through expert judgment. The sample consisted of 767 respondents using the inverse square root method. Initially, the PLS SEM approach was applied, which was then verified through the CB-SEM covariance model, using the robust extended maximum likelihood estimation method, and subsequently with Bayesian estimation (B-SEM). This was followed by a path analysis of each structural model, thus estimating the proposed relationships for academic performance, perceived usefulness, student satisfaction, e-learning system use, instructor quality, course content quality, educational system quality, support service quality, technical system quality, and self-regulated learning. Finally, a comparative performance evaluation was conducted using the RMSEA, SRMR, CFI, and TLI indicators between the CB-SEM model and Bayesian SEM models with diffuse priors; Bernardo's reference, Bayes-Laplace uniform, and specific informative priors, the latter showing the best fit compared to the CB-SEM approach and other Bayesian models. In this way, the measurement and structural models of the sustainable e-learning system and academic performance were successfully constructed and validated, as well as their causal relationships from the Bayesian perspective.
