This present study aims to describe the spatial ability of junior high school students observed from the difference of Mathematics ability. The subjects of the study are three junior high school students. The selected students are; the one with high-level Mathematics ability, the one with medium-level Mathematics ability, and the one with low-level Mathematics ability. The task of Geometry Problem Solving and interviewing the subjects are applied to collect the data. The finding shows that the subject with high-level Mathematics ability does not have difficulties in solving the task of Geometry Problem Solving on three spatial components. Nonetheless, the subject with medium-level Mathematics ability and the subject with low-level Mathematics ability have difficulties in solving the task of Geometry Problem Solving on one of the spatial components. © 2018 Author(s).
