The purpose of this study is to get a better understanding on school culture in the United States and Turkey. In this quantitative investigation, data were collected using the "School Culture Inventory" from 157 teachers in Izmir, Turkey and 161 teachers in the United States. The findings show that both countries have a positive culture. A positive school culture enhances academic achievement, and culture is perceived more positively in medium SES schools in Turkey and low SES schools in the USA in terms of socioeconomic status (SES). The US schools rated higher in terms of improvement culture and the teaching culture while Turkish schools rated higher in terms of teacher collaboration.
