The Bar Mitzvah and Bat Mitzvah are a "rite of passage," a crossover from childhood to adulthood; a milestone in a Jewish life.

Judaism deems a boy a "Bar Mitzvah" when he reaches the age of 13 and a girl becomes "Bat Mitzvah" when she turns 12. (Reform Jews celebrate both boys and girls coming of age on their 13th birthday). At that point the child, who is no longer a child in the eyes of Jewish law becomes responsible for his own deeds, spiritually, ethically, and morally.

For many children, preparing for a Bar Mitzvah ceremony is a highlight of their growing awareness of Judaism and is a moment when they are the center of attention (a most craved position). To participate in the service gives a sense of belonging. To be the focus of all the fussing provides a sense of importance. If it is done right, the experience will be positive and will build a warm, happy, lasting bond with Jewish life.

Furthermore, a Bar and Bat Mitzvah is timed to coincide with the first stretch of adolescence. As a teen reaches for identity throughout these rocky years, Bar and Bat Mitzvah memories fend for what it means to be a Jew. In the best case they will foster a sense of connection with all Judaism has to offer.

In modern times, the religious service is followed by a celebration that is often as elaborate as a wedding reception.
