Perfectionism is defined as the tendency to have high goals and standards for one's self (Flett et al., 1989). Setting high and even unrealistic goals in education can be negative for students as this can cause anxiety, procrastination, and low self-efficacy. The present study aims to determine the relationship between academic perfectionism and research anxiety levels for preservice teachers and to compare both of these with variables such as gender, year of study, department, primary department preference on the university exam, and career plan, to demonstrate the links between these variables. The participants are 469 undergraduate students who study at the Aydin Adnan Menderes University Faculty of Education. The Academic Perfectionism Scale (Odaci et al., 2017), Research Anxiety Scale (Büyüköztürk, 1997), and a Personal Information Form were used as data collecting tools. The results have shown that female participants have significantly higher idealization scores than male participants. Early childhood education and art education students have significantly higher comparison scores than music education students. Fourth-year students have significantly higher scores on research anxiety than first-year students. Participants whose primary department preferences on their university entrance exams were not their present departments have significantly higher research anxiety scores than the participants whose first choice was the department where they study. Participants who plan to become academics have significantly higher idealization scores than participants who want to do a job outside of their fields of study. Participants who want to be academics have significantly lower research anxiety scores than those who want to be teachers and those who want to do a job outside of their fields of study. In addition, there is a significant medium relationship between the participants' self-doubt subscale scores and their research anxieties. Moreover, there is a significant but weak relationship between participants' comparison subscale scores, academic perfectionism total scores, and their research anxieties. The results were discussed in the light of the literature.
