The transformation from conventional learning to full scale online learning during the COVID-19 pandemic has created challenges for the academics in various fields of study, who have to gain understanding on both the internal and external factors that will enable the learners to have positive learning behaviors that will enable the learners to achieve the learning outcomes based on the objectives of the study program. This research, thus aimed to analyze the online learning acceptance and study the influence of personal factors of the students on the online learning during the COVID-19 pandemic. The sample consisted of 386 Thai undergraduate students. The findings showed that the online learning acceptance during the COVID-19 pandemic comprised three components. Male students tended to accept the perceived benefits at the higher level than that of female students; students in the Digital Technology for Business Program accepted the perceived benefits at the same level with that of students in the Digital Technology for Design Program. The first year and fourth year students tended to accept the perceived benefits at the higher level than those of students in other class year levels; the fourth year students tended to accept that online learning was less complicated than those of students in the other class year levels; and finally, the first year students tended to acknowledge that they had trialed with online learning at the higher level than those of students in the other class year levels.
