The Chaldean Archdiocese of Erbil organizes pastoral ministry through its parishes.  In addition to a rich liturgical and sacramental life, the parishes provide catechesis and youth ministry.

The Catechism Central Committee was established to unite the work of the 11 catechism centres in the Erbil Governorate and give the catechism teachers access to sufficient resources and training opportunities to empower and encourage them in effective evangelization. Catechism is one of the most important pastoral activities of the Chaldean Archdiocese of Erbil.  More than 2,000 students from both genders (aged between 5-18 years) benefit from the catechism programs.

The Archdiocese has seven parishes
