This research aimed to describe the geometry visual skill at level 0 (visualization), level 1 (analysis) and level 2 (ordering) according to Van Hiele Theory towards field independent students in Junior High School. This research was a survey. The research conducted for grade 8 students of Junior High Schools with a range of age between 14 until 15 years old. The samples were selected using proportionate stratified random sampling technique which was a combination of stratified sampling technique and proportional sampling technique followed by random sampling technique. This technique was used to determine the sample proportionately for each strata. The samples consisted of 103 students from 4 representative high strata schools. The data were collected by using tests. Data analysis was done with quantitative and qualitative approach. The result showed that most of students have FD cognitive style. Most of FI students' score show a better result than FD students' score in each level of van Hiele. There is not specific pattern to describe students' visual skills for each van Hiele level. It does not indicate that the higher the level of van Hiele achieved by students, the better the visual skills of students. © 2018 Published under licence by IOP Publishing Ltd.
