Organizational digital transformation comprises a number of significant factors for measuring success, each of which involves different evaluating criteria. This research was aimed at developing indicators and criteria behind Thai universities' organizational digital transformation by the use of the quantitative research method and a questionnaire for data collection. The informants included administrators of six Thai universities: 303 high-level administrators, 174 middle-level administrators, and 18 low-level administrators. From the total of 495 administrators, 262 completed and returned the questionnaire. Analyses were then performed based on the statistics showing frequencies and percentages. The findings showed nine key indicators, nine sub-indicators, and 10 evaluating criteria that are appropriate for evaluating the work outcomes in the dimension of digital transformation. The most appropriate indicators were the digital strategies and personnel. The results would benefit administrators, academics, researchers, and the officers involved in deploying the work of organizational digital transformation under the educational context. The benefits would be in planning and developing the policy in digital transformation of Thai universities that is in the right direction and more clarified. Other institutions would also be able to effectively and successfully apply the indicators in their digital transformation process.
