Objectives While many studies have explored the components of digital competence, essential in our 21st-century society, their primary focus has been on adults and students from elementary through high school. This leaves a noticeable research gap concerning digital competences for preschool-aged children. This study seeks to address that gap, aiming to identify and outline digital competence sub-domains and content appropriate for preschoolers. Methods For this study, a literature review was conducted on 33 studies sourced from databases, employing snowballing techniques. The digital competences of preschoolers were delineated by re-categorizing and renaming those identified in the literature, with a focus on essential content and keywords. This process also involved considering overlaps, appropriateness, comprehensiveness, equivalence, and exclusiveness among the titles and scopes of components, and developmental characteristics of early childhood. Results As the results, six areas of digital competence for preschool children were identified: 1) Understanding of digital media operation and usage, 2) Digital media and content creation and appreciation, 3) Digital initiative and problem-solving, 4) Digital emotional intelligence, 5) Digital safety and healthy habits, and 6) Digital communication and participation. Additionally, this study detailed the components of each area under the facets of knowledge, skills, attitudes, and values. Conclusions The study findings indicate that the digital competences for preschool-aged children span technical, cognitive, socio-emotional, and ethical dimensions. As such, they should be holistically nurtured across the five learning areas of the national curriculum.
