The study aims to develop a web-based assessment to diagnose students' abilities through the four-tier test (FTDT). The development has three stages: design, development, and testing. Tests are conducted sequentially by expert assessment and field testing. Field testing was conducted in 10 schools representing three school clusters. The results of the expert assessment were analyzed using minifac (facets Rasch), while the field tests were analyzed descriptively. The results prove the feasibility of FTDT web-based assessment as a measuring and diagnostic tool. Testing on 743 students confirmed the accuracy and reliability of the FTDT web-based assessment. The diagnostic results show that students in high clusters are better than in middle and low cluster schools, with the highest achievement being the decision Lack of Knowledge type 2. The responses from teachers and students regarding the use of FTDT web-based assessment have implications that socialization is needed to learn more about the objectives and outputs of the diagnostic test. © 2022 IEEE.
