This research was motivated by the transition from an inefficient manual attendance system to a digital information system at Pondok Modern Nurul Islam, an Islamic boarding school. The success of such a system depends heavily on user acceptance. This study aims to compare the effectiveness of the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) in explaining user acceptance of the digital attendance system. This study used a quantitative approach, collecting data from 203 users (students, teachers, and staff) through a survey questionnaire. The data were analyzed using the Structural Equation Modeling-Partial Least Squares (SEM-PLS) method. The results show that both models can explain user acceptance. In the TAM model, all hypotheses were significant, with Perceived Usefulness being a dominant factor. In the UTAUT model, Performance Expectancy, Effort Expectancy, and Social Influence significantly impacted Behavioral Intention. The UTAUT model was found to be more comprehensive in explaining acceptance, although the hypothesis testing the influence of Facilitating Conditions on Behavioral Intention was rejected. This study concludes that UTAUT offers a more robust framework for this context, but TAM remains a simpler, relevant alternative for assessing technology adoption..
