This study determined the best-fit model for attitude towards online learning of grade 12 students in Region XI based on perception on e-learning, personal issues on e-learning, and the environment of e-learning. This study employed a causal study design and a stratified sampling technique in selecting the 400 respondents. With the electronic survey facility through Google Forms, data were collected utilizing standardized adapted questionnaires. The study utilized the mean, standard deviation, Pearson’s product-moment correlation, regression analysis, and structural equation model as statistical tools. Results revealed that the level of student perception on e-learning was high; the level of their personal issues on e-learning was high; the level of e-learning environment was high; and the level of attitude towards online learning was high. Moreover, a significant relationship existed between the exogenous and endogenous variables. Furthermore, perception on e-learning, personal issues on e-learning, and the e-learning environment influence the attitude towards online learning. Finally, among the five generated models, Model 5 best-fitted student attitude towards online learning in terms of interest in computers and adoption of online learning and ease-ness in using online learning, with perception on e-learning in terms of perceived usefulness of e-learning and perceived self-efficacy of using e-learning; personal issues on e-learning in terms of health, conflict resolution, and motivation; and environment of e-learning in terms of ethics and professionalism, and program effectiveness.
