The aim of this study is to determine to which extent the measurement tool development steps that should be followed during the development of self-efficacy scales used in education and psychology are met. In line with this general purpose, the following questions tried to be answered for each study that was examined regarding the five sections, which were introduction, theoretical background, item writing, validity and reliability (for first and second implementation). In the scope of the study, document analysis was implemented. The self-efficacy development studies in the national and international literature between 1997 and 2018, which were possible to get in the electronic environment, were examined in the scope of the research. It was determined that one of the deficiencies often seen when the self-efficacy scales are examined is that the psychological structure is not defined operationally. And also the mistake that was often encountered in scale validity studies was seen to be making both explanatory and confirmatory factor analyses on the same data set. One of the most remarkable mistakes done is the confusion of scale and questionnaire. That there is a confusion regarding concepts means the scale developers do not know the difference between a scale and a questionnaire yet.
