The Israeli government operates two separate school systems for its 1.8 million school children: a Jewish system and an Arab system. The students in the latter are Palestinian Arab citizens of Israel, nearly one quarter of all Israeli school children. The author argues that, despite small advances in recent years, the discriminatory practices against Palestinian Arab school children that are institutionalized in its education system place Israel in violation of its international legal obligations.The greatest inequalities are found in kindergartens for three- and four-year olds and in special education.
