This law, which is known by public as 4+4+4 and made a sudden change in Turkish education system, has brought along many discussions. In this study, it is aimed that the impacts of 4+4+4 education system, which is created with the purpose of increasing the period of compulsory education in Turkey to the average of EU and OECD countries and providing a more qualified education environment to the students, are analysed since the time it has come up for the first time.
