This study aims to determine the development and effectiveness of cognitive test instruments to train students' higher-order thinking skills (HOTS) in educational statistics courses. The method employed is research and development (R&D) based on the ADDIE model, which includes analysis, design, development, implementation, and evaluation. The research sample was purposively selected, consisting of PGMI students at Universitas Islam Negeri Sultan Maulana Hasanuddin Banten who were enrolled in educational statistics courses. The research findings indicate that lecturers need to refine syllabi according to the specified curriculum, develop cognitive test instrument grids in the form of questions with indicators, and design statistical questions based on religious moderation using the ADDIE model. The development of cognitive test instruments based on religious moderation is effectively used to measure higher-order thinking skills (HOTS) in educational statistics for students. The implications of this research highlight efforts to train students' higher-order thinking skills through educational statistics based on religious moderation using cognitive test instruments.
