Few studies have examined the extent to which public children's service sys
tems respond to the mental health problems of children in state custody. Th
is is an important issue because previous research suggests that little att
ention is given to children's mental health service needs when judicial and
service decisions are made about children who enter state custody. The cur
rent study addresses the issue by examining the extent to which one state's
children's service system is responsive versus reactive to the mental heal
th problems of the children in its care. A responsive system is one in whic
h services are provided to meet each child's unique mental health needs. A
reactive system is one in which service providers take actions to avoid pro
viding needed mental health services. Our results describe a service system
that is more reactive than responsive to children's mental health problems
