The purpose of this research is to identify the situation through content analysis of scale development studies conducted by Turkish researchers in the field of preschool education. Thus, the overall trend of scale development research in preschool education was established. This research is a document analysis study. The documents studied are national and international articles published by Turkish preschool teachers. These articles were content-analyzed. Scale studies conducted between 2018 and 2023, which encompass preschool education, educators, parents, and preschool resources, were searched. In total, 63 article studies were included in this content analysis. For data collection, a data collection form was prepared for content analysis, inspired by the 'Publication Classification Form' which was used to conduct a detailed scanning process. According to findings of the research, the scale of development studies (63%) conducted in pre-school education, largely in 2018, with two authors, was larger than that of adaptation studies. The majority of studies (49%) were published in the Turkish database TR ULAKBIM, with a focus on the social-emotional domain (16%) and science-education (67%). It was found that the descriptive method was preferred as the research method, that children were the majority of the sample (38%), that the sample size was chosen between 201 and 500, and that factor analysis and descriptive analysis were employed as analysis methods.
