A homeschool co-op is a group of families who meet together and work cooperatively to achieve common goals. Co-ops can be organized around academics, social time, the arts, activities, crafts, service work, or projects — or some combination of these.

Activities and classes that are part of a co-op may be led by parents, or the parents may chip in to pay all or some of the teachers and activity leaders. There may be as few as three families in a small co-op or as many as several hundred children in the largest co-ops.

Co-ops may meet in homes, churches, libraries, or community centers. In the United States, homeschool co-ops commonly meet once a week from “after Labor Day” to “before Memorial Day” — but some meet twice monthly or once per month, year round. A co-op’s meeting frequency and yearly calendar is up to the co-op organizers.
