The research adopts the Technology Acceptance Model (TAM) developed by Fred Davis to examine the relationships among system implementation, perceived usefulness, perceived ease of use, and administrative performance effectiveness. A mixed-method approach was applied, combining qualitative description and quantitative analysis. Data were collected from 32 respondents consisting of classroom teachers, subject teachers, and school operators using a Likert-scale questionnaire. Regression analysis results indicate that digital report card implementation significantly affects perceived usefulness (β = 0.912; p &lt; 0.05) and perceived ease of use (β = 0.618; p &lt; 0.05). Furthermore, perceived ease of use has the strongest influence on administrative performance effectiveness (β = 0.805; p &lt; 0.05). The model explains 94.9% of the variance in teachers’ administrative performance effectiveness. The findings indicate that system usability plays a crucial role in improving administrative efficiency in primary schools.</p> neneng neneng Ajeng Savitri Puspaningrum Copyright (c) 2026 Jurnal Data Mining dan Sistem Informasi https://creativecommons.org/licenses/by-sa/4.0/ 2026-02-18 2026-02-18 7 1 1 14 10.33365/jdmsi.v7i1.1509
