Entry into school represents as much a challenge for children as it does for their parents. The authors examined the ways in which transition practices help children and their families feel prepared for school entry, as measured by the child's emotional adaptation during the first days in class and the family's sense of being prepared for this transition. Data were collected from a sample of 412 parents. The results indicate that children's emotional adaptation during the first days in school is related to their families' preparedness for school entry. Moreover, families' preparation is partly explained by the number of transition practices perceived by the parents. These data support the importance of transition practices in the preparation of the family as a unit. Transition practices could serve to reassure parents and their children that the school is ready to welcome them.
