The aim of this study is to conduct validity and reliability study of the Environmental Awareness and Attitude Scale for Preschool Children .This study is conducted with 310 children who are having preschool education. At the end of the factor analysis results, there are three factors that explain 44.02% of the total variance in Environmental Attitude subscale. In the Environmental Awareness subscale, 3 factors that explain 40.94% of total variance were found. The correlation coefficients between the factors of the Environmental Awareness subscale were r =.80, .78 and .83 and for the Environmental Attitudes subscale were r =.70, .79 and .72 respectively. In statistics done for the reliability study of the Environmental Attitudes subscale, the Spearman Brown reliability coefficient was found to be .75, and the Cronbach’s alpha reliability coefficient was found to be .73. For the Environmental Awareness subscale these coefficients were found to be .65 and .66 respectively. For the whole scale the Spearman Brown reliability coefficient was found to be .60, while the Cronbach’s alpha reliability coefficient was found to be .67. According to t-test results concerning the significance of the difference between the upper and lower 27% of the total scores, there is a significant difference in favor of the upper group. The item discrimination power of Environmental Attitudes subscale varies between .34 and .47, for Environmental Awareness subscale it varies between .32 and .40. The scale’s average item discrimination power is .38. This value indicates that the scale has a discrimination feature. As a result it can be claimed that a scale with 26 items and two subscales is a valid and reliable scale for 60-66 month old children.
