Kinship placements are associated with achieving permanency but “progress moves” into kinship settings may disrupt stable placements, which are also beneficial. This study used event history models to compare rates of permanency among children transitioning between kinship and non-kinship foster placements immediately after being taken into care in the United States (n = 4,869). Children transitioning from non-kinship to kinship care achieved permanency faster than children staying in non-kinship care. Moderation analysis showed that all children except teenagers benefited from more rapid transitions from non-kinship to kinship care, highlighting the importance of locating willing kin caregivers and providing services to support rapid transitions.
