Israel has a school life expectancy of 15 years and a literacy rate of 97.1% according to the United Nations. The State Education Law, passed in 1953, established five types of schools: state secular, state religious, ultra orthodox, communal settlement schools, and Arab schools. The public secular is the largest school group, and is attended by the majority of Jewish and non-Arab pupils in Israel. Most Arabs send their children to schools where Arabic is the language of instruction.
Education is compulsory in Israel for children between the ages of three and eighteen. Schooling is divided into three tiers – primary school (grades 1–6), middle school (grades 7–9), and high school (grades 10–12) – culminating with Bagrut matriculation exams. Proficiency in core subjects such as mathematics, the Hebrew language, Hebrew and general literature, the English language, history, Biblical scripture and civics is necessary to receive a Bagrut certificate. In Arab, Christian and Druze schools, the exam on Biblical studies is replaced by an exam on Muslim, Christian or Druze heritage. In 2003, over half of all Israeli twelfth graders earned a matriculation certificate. The Hebrew University of Jerusalem and Tel Aviv University are ranked among the world's top 100 universities by Times Higher Education magazine. Israel ranks third in the world in the number of academic degrees per capita (20 percent of the population)
