The main objective of this study is to investigate students’ Mathematical Literacy(ML) in elementary, secondary and high school. The purpose of ML is students ability to use mathematics to solve context related problems in real world .In the theoretical framework of ML in the international PISA study, mathematics is divided four categories space and shape, change and relationships, quantity and uncertainty. A sample of 90 students from elementary school (10-11years old), 118 students from secondary school (14-15 years old) and 70 students from high school (17-18 years old) were tested on mathematical literacy and the Witkin’s cognitive style (Group Embedded Figure Test) test. The findings of this study showed that students in elementary school were more successful and literate than secondary and high school students. ML of secondary and high school students showed no significant difference. Also obtained results indicate that FI students in ML test were better than FD students.
