Assessment instruments are very important in learning poses so that learning can run optimally. Problem-solving skills and Computational Thinking (CT) are very important skills in today's digital era. The purpose of this study is to analyze the need for Delphi programming-oriented mathematical information system problem-solving assessment instruments. The research method used is qualitative with a case study approach which includes observation, interviews, documentation studies, and tests. The subjects of this research are several lecturers and students of Mathematics Education. The data analysis technique used is the flow method and descriptive comparison. The results show that the use of Delphi programming-oriented mathematical information system problem-solving assessment instruments is very important to increase student engagement, provide contextual relevance, and build relationships between subject matter as well as train students to think critically and creatively in solving problems. This study emphasizes the importance of developing Delphi programming-oriented mathematical information system problem-solving assessment instruments that are relevant to technological developments and daily life, thereby stimulating creative thinking, exploration, collaborative learning, and computational thinking. Thus, this study emphasizes the importance of considering the use of Delphi programming-oriented problem-solving assessment instruments on mathematical information system materials.
