Prior to April 2016, data was collected about the activities and status of care leavers on their 19th birthday as part of the annual Outcome Collection (OC) return*.  This includes information about whether the local authority had remained in touch with the young person, their education, training or employment status and the suitability of their accommodation. 

Within SAIL, this dataset must be linked to the primary Children Looked After census (LACW) to get child characteristics (week of birth, gender, ALF). 

The Outcomes Collection return was a series of annual returns made by local authorities with respect to care leavers.  The OC1 focused on educational qualifications at 16 and the OC3 focused on their circumstances on their 19th birthday.    

The OC2 focused on children who had been continuous looked after for 12 months, compiling information at a local authority level with respect to offending, health promotion checks, immunisations, dental checks, health assessments and substance misuse problem identification and intervention.  This information is now collected as part of the Children Receiving Care and Support return.  Prior to 2016, it was part of the Children in Need return.
