Five groups of providers were identified. Results showed that the service provider groups worked with different types of children and families based on several demographic characteristics. Groups also differed on the basis of service delivery variables. Expected differences between the groups were found on the basis of age at entry, eligibility category, and intensity of services. Variation based on other characteristics, such as ethnicity, income, and maternal education, suggest that services may not always be provided on the basis of child or family need. Limitations and future research are discussed.
