Yes, and that is a key part of Liberal Judaism. Recognising that bar/batmitzvah, although significant, does not, in modern society, mark a child’s becoming an adult, the ceremony of Kabbalat Torah at age 15+ allows girls and boys to affirm their commitment to Judaism as a consequence of a personal decision.
Kabbalat Torah is a firmly established religious observance in Liberal Judaism, which encourages students to think about issues through the lens of Jewish tradition and Liberal Jewish values.
Apart from formal learning, most courses include active participation in the religious and cultural life of the community. Students are also invited to participate in events with young people from other communities and on trips to places of Jewish interest in the UK and Europe.
Many post Kabbalat Torah students come back to the religion school to become class helpers, and later a number choose to become teachers.
