A classis is a group of churches within a geographical area that comes together to seek, discern, and submit to God's will, offer one another mutual support and accountability, find ways to live out a collective calling in the region, and allow for a healthy and sustained connection to the wider denomination.

A classis has the authority to deal with matters that concern its churches in common and its decisions are binding on the churches in its region. A minister, elder, and deacon from each congregation are delegated to attend each classis meeting.

There are 48 classes in the CRC, 11 in Canada and 36 in the United States, and one with congregations on both sides of the border.

For denominational ministry services, classes are divided into six regions and their subregions (view as a printable PDF). For representation on the Calvin College and Calvin Theological Seminary boards, classes are divided into 12 regions.

Below is a list of all classes, and links to their individual websites if available (if we're missing one, please email us).
