The recent surge of the fourth industrial revolution has set forth demands for a new generation of the labor force with a comprehensive set of skills to meet the standards of the global market. Despite widespread concerns about educational reforms and renovations to enhance the workforce capacity in terms of information and communication technology (ict) skills, research into the digital proficiencies of students has been limited in vietnam. This dataset contains 1061 observations on the digital competency level of 10th-grade students in 20 surveyed schools from five provinces in vietnam. The investigation, joining frequentist and bayesian analyses, aims to provide valuable insights into the current state of childrens attitudes, behaviors, competency levels, and use of ict within the vietnamese educational context. The values of the dataset lie in its proposed scientific framework for replication in multiple regions and contexts as well as the feasibility of categorical regression techniques together with bayesian statistics for hierarchical regression analysis. 2019 By the authors.
