The implementation of the evaluation of learning outcomes for students allows the emergence of biases that can cause students' abilities to not be depicted properly. This study aims to determine the ability of students based on the evaluation test of chemistry learning in high school. The research subjects involved 41 students. Data analysis using Wright Map on Rasch modelling based on chemical bond indicators such as 1) the process of forming ionic and covalent bonds, 2) differences in ionic and covalent bonds from physical and chemical properties, 3) analyzing the type of chemical bonds formed, and 4) determination of the shape of the molecule. Based on the results of the Wright Map, the percentage of students' abilities as much as 2% are in the high, 78% are in the medium, and 8% are in the low and very low categories. Overall, students have difficulty analyzing the type of chemical bond formed and the shape of the molecule. By using the Wright Map, the actual abilities of students can be seen clearly and accurately. This is very helpful for teachers to classify students whose scores are still below the average so that a corrective test can be done.
Key words: Chemical bond test / student ability / wright-map
