were murdered during the Holocaust. After further reductions due to postwar emigration and assimilation, only about 2,300 Jews remain today (0.04% of the population). There are 18 state-registered religions in Slovakia, of which 16 are Christian, one is Jewish, and one is the Baháʼí Faith. In 2016, a two-thirds majority of the Slovak parliament passed a new bill that would obstruct Islam and other religious organisations from becoming state-recognised religions by doubling the minimum followers threshold from 25,000 to 50,000; however, Slovakia's then-president Andrej Kiska vetoed the bill. In 2010, there were an estimated 5,000 Muslims in Slovakia representing less than 0.1% of the country's population. Slovakia is the only member state of the European Union to not have any mosques. Education The Programme for International Student Assessment, coordinated by the OECD, currently ranks Slovak secondary education the 30th in the world (placing it just below the United States and just above Spain). Education in Slovakia is compulsory from age 6 to 16. The education system consists of elementary school which is divided into two parts, the first grade (age 6–10) and the second grade (age 10–15) which is finished by taking nationwide testing called Monitor, in Slovak and math. Parents may apply for social assistance for a child that is studying on an elementary school or a high-school. If approved, the state provides basic study necessities for the child. Schools provide books to all their students with usual exceptions of books for studying a foreign language and books which require taking notes in them, which are mostly present in the first grade of elementary school. After finishing elementary school, students are obliged to take one year in high school. After finishing high school, students can go to university and are highly encouraged to do so. Slovakia has a wide range of universities. The biggest university is Comenius University, established in 1919. Although it's not the first university ever established on Slovak territory, it's the oldest university that is still running. Most universities in Slovakia are public funded, where anyone can apply.

Slovakia has several privately funded universities, however public universities consistently score better in the ranking than their private counterparts. Universities have different criteria for accepting students. Anyone can apply to any number of universities. Culture Folk tradition Folk tradition has rooted strongly in Slovakia and is reflected
