Amid the accelerating integration of digital technologies into educational ecosystems, a critical gap remains in the systematic evaluation and strategic enhancement of teachers’ digital literacy across Indonesia’s diverse regions. This encourages the pressing need for validated assessment instruments and targeted interventions to support educators' competencies. This study disseminates a rigorously validated digital literacy measurement tool grounded in the Instant Digital Competence Assessment (IDCA) framework and investigates the digital literacy levels of elementary school teachers in several provinces of Indonesia, i.e., DKI Jakarta, West Java, and West Sumatra. Employing a quantitative-descriptive survey design, data were collected from 296 teachers through online questionnaires. The sample size was calculated using Slovin’s formula with a 10% margin of error, followed by simple random sampling for participant recruitment. The IDCA instrument measures digital literacy across three core dimensions: Technological, Cognitive, and Ethical. The findings reveal that teachers generally exhibit a "fairly good" level of digital literacy. Notably, respondents reported higher competence in the Ethical and Technological domains, particularly in areas such as online safety, respectful digital interaction, and the ability to navigate and utilize digital tools. However, significant deficiencies were identified within the Cognitive dimension, especially concerning critical evaluation of information credibility and analytical processing of digital content. These results highlight the urgent need for strategically designed professional development programs that prioritize the cultivation of higher-order cognitive digital skills. Furthermore, the study advocates for robust educational policies to bolster teacher readiness in delivering technology-enhanced instruction, thereby ensuring meaningful integration of digital tools in 21st-century classrooms.
