The education system in Romania is based on several key principles, including that education is a national priority and free of charge. It consists of pre-primary, compulsory, and high school education. Pre-primary education is for ages 3-7 and is mostly provided in public kindergartens. Compulsory education combines 8 years of primary school (ages 7-11) and lower secondary/gymnasium (ages 11-15). Both levels are free of charge. Compulsory education ends with a national exam. High school aims to further develop students' skills and personalities and ends with another national exam allowing entry to higher education.
