This quantitative study examined Malaysian teachers' perception towards using GeoGebra in mathematics teaching. The relationship between teachers' Perceived Current Competencies (PCC) of GeoGebra, and Intention to Use (IU) it as well as the difference between male and female teachers and between users and non-users of GeoGebra were investigated. An online survey was administered on 132 teachers who had already participated in GeoGebra workshops in Malaysia. The results of correlation and independent t-test revealed a positive relationship between teachers' perceived current competencies with their intention to use GeoGebra in teaching mathematics. There were no significant differences between male and female teachers in their intention to use GeoGebra in teaching mathematics. On the other hand, significant differences were observed between users and non-users of GeoGebra in their intention to use GeoGebra in their mathematics classrooms.
