Social Workers, Early Help workers and other people who are not family members but need to be linked to the student, should be added from the student profile. You'll need to add them in the same way you add guardians, in the Family, Guardians and Contacts section.
Click +Add to add them. Add in their details, choosing the most appropriate role.
Adding Social Workers for the Covid dashboard
If you are wanting to indicate that a student has a social worker for the purposes of Covid-19 attendance reporting, you can follow our steps on adding the student to a Social Worker custom group in our COVID-19: Current guidance for schools.
Adding Looked After (In Care) Status
You are also able to add Looked After (In Care) status to the child's profile, with a status of With Parents (under the supervision of social services). Our article on Adding a Looked After (In Care) or Post Looked After status shows how to add this.
