The purpose of this study is to develop a scale, the Educational Technology Standards Scale (ETSS), to determine how effectively and appropriately preservice teachers use educational technologies. 460 seniorclass preservice teachers (189 male and 271 female) from six departments in the Education Faculty of Selçuk University in Turkey participated in this scale-development study in the academic year of 2005–2006. Analysis of the findings reveals that the scale (at the national level) helps universities in Turkey evaluate themselves for their education about educational technologies.
