 In 2009 a study was launched by the Council for Religious Institutions in the Holy Land, an interfaith association of Jewish, Christian, and Muslim leaders in Israel and the Occupied Territories, which planned on making recommendations to both sides' Education Ministries based on the report.It was supervised by a psychiatrist, Prof. emeritus Bruce Wexler of Yale University and his NGO – "A Different Future" and commissioned a joint Palestinian-Israeli research team headed by Professors Daniel Bar-Tal (Tel Aviv University) and Sami Adwan (Bethlehem University), which employed research assistants (6 Israeli and 4 Palestinian bilingual research assistants) to analyze texts of 370 Israeli and 102 Palestinian books from grades 1 to 12.Both "The Guardian" and AAP mention 3000 approved textbooks from 2011 as subject to the study's analysis, including those used in the ultra-Orthodox Jewish community's educational system.
