Abstract This study aimed to adapt the scale developed by Day and Hurrell (2013) and later adopted by Lau (2021) into Turkish and to assess middle school mathematics teacher candidates' confidence in teaching algebra. We also examined the validity and reliability of the scale and evaluated the candidates' confidence levels. A total of 267 senior preservice mathematics teachers from nineteen universities participated in the study. We collected the data using a nine-item Likert-type questionnaire. During the adaptation process, we translated the scale into Turkish, obtained expert feedback from two mathematics education specialists, revised the items based on their suggestions, and conducted a back-translation through another expert to ensure linguistic accuracy. We performed confirmatory factor analysis, which supported the proposed factor structure and provided evidence of satisfactory psychometric properties, including adequate convergent validity and high internal consistency. The descriptive results showed that preservice teachers reported moderate to high levels of confidence in teaching algebra, although we observed notable individual differences across participants. These variations suggest that teacher education programs may need to provide additional targeted support to strengthen preservice teachers' confidence in teaching algebra. We expect that this valid and reliable instrument will serve as a useful tool for examining confidence across different variables, identifying potential gaps, and improving teacher education programs more effectively.
