In this study, a historical and international analysis of early childhood education in Turkey is made. More specifically, we explore the trend in pre-school enrolment, compare Turkey's enrolment rate with other countries, study whether access to pre-school is related to social class and gender, and investigate the impact of pre-school attendance on later academic performance. We use data from the PISA (Programme for International Student Assessment) 2012 study and World Bank EdStats. The results indicate that Turkey's pre-school enrolment has strongly increased over the years. However, compared with other (newly) industrialised countries, Turkey has a very low pre-school enrolment rate. Regression analyses revealed that pupils from wealthy families are much more likely to attend pre-school than pupils from poor families, while no difference was found between girls and boys. Importantly, pre-school attendance was related to higher academic achievement, even though pupils from wealthy families benefited more than middle-class and poor pupils.
