Projects that enable students to increase their skills in this subject by using scientific research methods also contribute positively to the development of multidimensional thinking skills. In this study, it is aimed to examine the measurements obtained by scoring the projects prepared by the pre-service teachers with independent raters (juries) with the theory of generalizability. The research was designed in the survey model. There are 12 faculty members and 6 projects in the study group of the research. The data collection tool used in the research and the evaluation criteria of TUBITAK research projects, which are consistent with the goals and achievements of project preparation, were used. Each project was given to the juries who would evaluate each project, and the juries scored the projects considering the relevant criteria. The lowest score for each criterion was determined as 1 and the highest score as 4, and the highest total score that can be obtained from the measurement tool is 40. Generalizability theory was used in the analysis of the data. G and phi coefficients, which are the reliability coefficients that can be increased and obtained, are examined. In the analysis of the research data, the EduG 6.1 program, which analyzes based on the generalizability theory, was used. Since the juries who made the scoring process in the research scored all the projects, a completely crossed design (jxpxm) was used. One of the results obtained from the research; The second highest contribution to the total variance is the items used as evaluation criteria. The items scored by the juries in order to evaluate the success of the students in the project contributed significantly to the total variance.
