The main purpose of this study is to demonstrate the students' attitudes towards project and performance tasks in Turkish Lessons and to develop a reliable and valid measurement tool. A total of 461 junior high school students participated in this study. In this study, firstly the preparation of items, specialist be consulted (content reliability) of the scale operations carried out pre-trial application; on the data, after were carried out item-total correlations, exploratory factor analysis and Cronbach's alpha to determine the reliability analysis. As a result, the analysis was observed to compose of 27 items and one factor of the scale. This one dimension that describes 32.10% of the total variance, for complete of scale Cronbach's alpha internal consistency coefficient is 917. What is determined is that item-test correlations range ,652 and ,409. The scale of fit index values are respectively RMSEA = 0.050, CFI = 0.97, IFI = 0.97, GFI = 0.90, AGFI = 0.88, and SRMR = 0.044. By looking at the values obtained from the analysis, "The Attitude Scale of Project and Performance Tasks in Turkish Lesson" tasks of the project and performance of students in secondary schools in their attitudes towards Turkish lessons can be used to determine the validity and reliability can be said that a vehicle.
