The United Synagogue is standing by its procedures for joining its youth division Tribe in the light of concerns about the participation of children who are not halachically Jewish.
Charles Daniels, a Mill Hill Synagogue representative at the US Council, questioned its policy at the council last year when he reported that some of those in Tribe summer camps were not halachically Jewish.
Prospective members submit an online application where they are asked to affirm they are Jewish.
But they do not undergo formal checks on their Jewish status.
