The Union for Reform Judaism (URJ) has found a strong and meaningful vehicle in the Community of Practice (CoP) strategy, which convenes cohorts of congregational leaders for long-term, innovative learning about a topic of shared interest. Participating congregations form teams of lay leaders and professionals who connect with other teams, learn together, and apply their learning by experimenting in their community. We take pride in the fact that URJ Communities of Practice are currently connecting and working to inspire change in more than 100 congregations.
