Summary: Study exploring the cost effectiveness of providing Action for Children Intensive Family Support (IFS) Services, based on findings from a sample of 43 families in two local authority areas. Measures the costs incurred to local authorities prior to the families accessing the IFS service, during the intervention and after IFS provision ceased. Looks at outcomes achieved by the families during the data collection time period. Key findings include: improved school attendance in two-thirds of children receiving support and reduced young offending rates in nearly 70% of 11-16-year-olds.
