This summary report describes the extent to which birthright israel has succeeded in affecting the lives of participants from the perspective of more than a year after the program’s launch in December 1999. Surveys of both participants and non-participants were analyzed to assess whether the initial positive feelings were sustained over time, and whether behavioral change occurred and was maintained. This report describes these survey findings based on responses from more than 1,500 participants and more than 150 non-participants from the United States. The study found that birthright israel participants became more Jewishly engaged as a result of their trip to Israel. More than one year after the launch trip, participants continued to view the experience as extremely meaningful. It had a very positive impact on their Jewish identity and their attitudes toward Israel, Judaism, and the Jewish people. The full report is available as A Mega-Experiment in Jewish Education: The Impact of birthright Israel.
