This study aims to develop a scale, the Educational Technology Standards Scale (ETSS), to determine how effectively and appropriately preservice teachers use educational technologies. For the development of the scale, the internationally approved NETS[middle dot]T standards from 2000 were used. These NETS[middle dot]T standards were used for determining what proficiencies teachers should have for the use of education technologies. A total of 460 senior-class preservice teachers (189 male and 271 female) from six departments in the Education Faculty of Selcuk University in Turkey participated in this scale-development study in the academic year of 2005-2006. As a result of the analyses, six factors took place in the 41-item scale. In general, the ETSS (at the international level) reveals the general situation of the education given about educational technologies in the education faculties of universities in Turkey. In particular, the scale (at the national level) helps universities in Turkey evaluate themselves for their education about educational technologies. Therefore, the results of the study are expected to contribute to the field of teacher training. (Contains 4 tables.)
