This research was conducted on a sample of (850) students (males-females) in the University of Tishreen to extract the psychometric properties of the scale and to check the significance of validity and reliability. The researchers used arbitrators' sincerity, honesty, and internal consistency to verify the veracity of scale's statements. Reliability was verified through consistency and repeated reliability, by using Cronbach's Alpha equation by split-half. The results found out that the values of honesty and reliability coefficients were high and statistically significant and demonstrated the validity of the scale. It was also showed there were statistically significant differences in the level of environmental awareness among male and female students.
