Question of the month:

Why did you not do a Rabbi's Kaddish after Ein Keloheinu at my daughter's Bat Mitzvah?

Answer:

Kaddish D'Rabbanan is not generally done following Ein Keloheinu; it is an optional practice to include it following Amar Rabi Elazar which is the Talmudic piece on the same page as Ein Keloheinu that we sometimes include, but not usually at a Bar/t Mitzvah and we did not at her Bat Mitzvah. Having said that, let me add that we don't do the Kaddish D'Rabbanan even when we do the Amar Rabi Elazar, while it is an optional practice, we generally follow the flow of the siddur which does not include the Kaddish D'Rabbanan at that point, but rather includes a note saying some people include it and if you want to do so, you can turn from page 182 back to page 71 to find it.
