This study explored the teachers’ digital literacy in secondary school and deciphered the most suggested way of enhancing secondary teachers’ digital literacy, overview levels, and the trends factors in the last five years of research. The methodologies in this study employed the traditional systematic literature review (SLR), which compiled some previous studies to be examined. The initial studies were only selected from an article published in a reputable journal indexed by Scopus. Of the 118 articles reviewed, 46 were selected to be included in the analysis. Significant findings summarize the fact that most of the last five-year research about teachers in secondary schools was impacted by the rapid development of technology and the demand for 21st-century skills. To summarize, as it is at the intermediate level, most secondary school teachers are digitally literate. However, future research may evaluate digital literacy training programs for teachers to assess what improvements should be made to delivery as well as existing frameworks used to test teachers’ digital literacy.

Teachers need digital competence to adapt easily to the current digital era. This study tries to discover the perceptions of vocational high school (VHS) teachers in Indonesia related to advanced digital competencies, which include information, communication, content creation, digital security, and problem-solving competencies. The multi-criteria Analytical Hierarchy Process (AHP) problem-solving method is used to rank the priority digital competencies that are most mastered by the respondents, and then their performance is validated by the fuzzy AHP artificial intelligence-based method. A poll was conducted with 392 respondents, with the research instrument adopting the digital competency measurement platform from DigComp. The study's results show that the fuzzy AHP method has proven that the classical AHP method is a very good way to prioritize VHS teachers' digital skills based on several factors. The two methods gave almost identical results in determining the priority order of VHS teacher digital competencies. The survey results reveal that VHS teachers in Indonesia must immediately develop their skills in terms of digital content creation and digital security. Teachers, teacher professional organizations, and decision-makers are expected to use the findings of this study as a reference in implementing VHS teacher digital competency improvement trainings.

Professional competency frameworks are important for aligning educational outcomes with workforce needs. While multiple frameworks exist across sectors, the underlying research-informed design principles guiding their development remain fragmented. This systematic review synthesises methodological approaches and proposes research-informed design principles used in developing professional competency frameworks across diverse professions, identifying common patterns and informing future framework design. A systematic review was conducted following PRISMA 2020 and SWiM guidelines. Searches across major academic databases yielded 3656 records. After screening, 47 studies met inclusion criteria. Data extraction focused on methodological processes and development activities. Thematic analysis was used to generate a set of design principles: (1) Foundational Inquiry and Evidence Gathering; (2) Consensus-Building and Collaborative Validation; and (3) Framework Development and Iterative Refinement. The development of competency frameworks is inherently cyclical, interdisciplinary, and iterative, blending empirical inquiry with collaborative validation. The identified research-informed design principles offer a transferable blueprint applicable across sectors, from healthcare to education and other industries. Thus, it is strongly recommended that future studies use these initial research-informed design principles to inform competency development. The systematic review has been registered with Open Science Framework (OSF).
