The objective of this study was to develop a reliable and validscale to measure the competencies of graphics class students concerning their graphic developments. The draftscale was applied to students, who had taken graphics course. Primarily, it was conducted with a normal distrubitonanalysis for reliability and validity of the scale. As a result of these processes, a valid and reliable measurement toolof three dimensions and forty-seven items were obtained. Since GDSES analyzes the graphic competencies ofpeople who have received a graphics course and helps identify the shortcomings in this topic, the scale can be usedin various studies.
