The DIVAYANA (Description-Input-Verification-Action-Yack-Analysis-Nominate-Actualization) evaluation application based on Positive-Negative Discrepancy is an information technology-assisted evaluation tool. This tool is very suitable for getting positive and negative inequality scores occur in the flipped learning implementation. The physical form quality of the DIVAYANA evaluation application based on Positive-Negative Discrepancy depends on user interface design. Therefore, educational evaluators need to clearly know the form of user interface design for the DIVAYANA evaluation application based on Positive-Negative Discrepancy. Besides the form of user interface design, educational evaluators must also know the user interface design quality of the DIVAYANA evaluation application based on Positive-Negative Discrepancy. This study aimed to show the form and quality of user interface design of the DIVAYANA evaluation application based on Positive-Negative Discrepancy. The method in this research was a development method that used the Borg and Gall model. The development refers to the design stage, initial design trials, and revisions to initial design trials. Tests on user interface design involved 104 respondents. The instrument was a questionnaire consisting of 15 questions. Analysis of the trial data used a quantitative descriptive technique. The results of the study show that the form and quality of the user interface design was good category. The finding of this research is a suitable user interface design for use as a basis for creating the physical form of a DIVAYANA evaluation application based on Positive-Negative Discrepancy. The contribution of this research to stakeholders (educational evaluators) is that it becomes a source of new knowledge that can increase the understanding of educational evaluators about the importance of user interface design functions in realizing evaluation applications.
