The aim of the study is to develop a scale named Classroom Life Perception Scale (CLPS) for determining the classroom life perceptions of the students toward lessons. The proposal scale, composed of 44 items, was applied to 2 study groups. The group of Exploratory Factor Analysis that aims to determine the psychometric properties especially the construct validity and reliability of CLPS consisted of 462 9th, 10th, 11th and 12th grade students. The group of Confirmatory Factor Analysis that aims to find out whether the factor structure demonstrated by CLPS was confirmed or not consisted of 282 9th, 10th, 11th and 12th grade students. As a result of the analyses, it has been determined that the scale consists of 28 items and it has a structure composed of three factors. The study showed that CLPS is a valid and reliable tool. Using CLPS with other data collection tools on classroom life perceptions of students will contribute to literature.
