The aim of this study is, to develop an environmental attitudes scale for secondary school students. Validity of sketch scale and reliability studies that are formed in two subscales and consists 41 items are applied to 512 students attending various secondary schools in Kocaeli in December 2011. The data are analyzed by using SPSS and LISREL. The construct validity of the scale is assessed by exploratory and confirmatory factor analysis. In line with exploratory factor analysis one item from the first subscale and five items of them from the second subscale were removed. The scale is formed in two subscales; first is called “Behavior” that is in one dimension, there are three dimensions in the second subscale these are; “Idea”, “Feeling”, “Willingness to Proceed in Action”. Consistency index obtained from confirmatory factor analysis put forward that the two subscales both with the theoretical structure and the confirmatory factor analysis are perfectly accorded. Item-total correlation is between 0.37 and 0.67 in the first subscale so this proves that the internal consistency is high. Also, values are determined as 0.845 for the Cronbach’s Alpha, 0.831 for the Gutman Split Half and 0.832 for the ratio of Spearman Brown. Item total correlation in the second subscale are between 0.30 and 0.77 and it is reached in the opinion of internal consistency is high. The values are determined as 0.81 for the Cronbach’s Alpha, 0.733 for the Gutmann Split Half and 0.736 for the Sperman Brown. This shows that the subscale is reliable. Also it is shown as a last finishing, whole the scale’s value is calculated and the value of Cronbach’s Alpha is found as 0.88. All these studies show that the developed environmental attitudes scales are compatible with theoretical structure and they proved their both reliability and validity
