It is worth noting that an estimated two-thirds of Lebanese students attend private schools. In April 2015, the Minister of Education, Elias Bou Saab, acknowledged the myriad challenges and gaps that exist in the Lebanese school system, and the public schools, particularly. While the Lebanese law stipulates that the national curriculum should be updated every four years, it has not been updated since 2000. Plus, because of the national disagreement over Lebanon's modern history, history textbooks cover historical events before 1943 only. The national exams (Grade 9 Brevet and Grade 12 Baccalaureate) were not graded in 2014. Preschool Education Preschool education aims to initiate children into the school environment. The goal of pre-school education is to create a favorable climate for children to communicate with others, develop their physical capacities, limb control and coordination of their movements, and educate their senses. Preschool education also takes into account the physiological, moral, and intellectual development of children. According to the World Bank database, the gross enrollment rate of preschool education is 62.5 percent for male, 68.3 percent for female, and 64.4 percent for total in 2006. Also, the private enrollment share for preschool education marked 80.3 percent in 2008. Basic education Elementary Level According to the Worlds database, gross enrollment rate of elementary level of basic education is for 96.8 percent for male, 93.9 percent for female, and 95.4 percent for total in 2007. Private enrollment share in elementary level is 67.6 percent in 2007. Intermediate level Primary completion rate of Lebanon (US$6,000 GNI per capita in 2007) is lower than that of Tunisia, Jordan, Iran, Algeria, West Bank and Egypt (all of which have lower GNI per capita). Primary completion rates have not improved during the period 1995/96 to 2003/04. In 2007, Primary completion rate is 79.8 percent for male, 83.3 percent for female, and 81.5 percent for total. According to UIS database, technical and vocational enrollment as percent of total enrollment in intermediate level is 5.1 percent in 2008. Private enrollment share of general education in intermediate level is 60.2 percent and that of technical and vocational education is 56.8 percent in 2008.
