Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
Jewish education
The Conservative movement has USY - United Synagogue Youth. The Modern Orthodox movement has NCSY - formerly National Conference of Synagogue Youth. BBYO is a non-denominational group, though most Jews associate it with the Conservative or Reform movements. The North American Federation of Temple Youth, known as NFTY, is the organized youth movement of Reform Judaism in North America. Funded and supported by the Union for Reform Judaism, NFTY exists to supplement and support Reform youth groups at the synagogue level. About 750 local youth groups affiliate themselves with the organization, comprising over 8,500 youth members.
