A sample answer to question 1

What does a key worker do in supported living or residential support?

A key worker is the named person who takes a lead on a small number of people's support. I build a close, trusting relationship, so I know their history, preferences, goals and what is important to them. I hold regular one-to-one key working sessions to talk about how things are going, what they'd like to do and any worries. I help to write and review their support plan and risk assessments, make sure their goals are being worked on, and coordinate with family, social workers, health professionals and other staff. I advocate for them, make sure their voice is heard in reviews and keep their records up to date. I also notice small changes in mood, health or behaviour and share them with the team. The role is about being consistent and making sure the person is the centre of every decision.

Common mistake to avoid: Describing it as the same as any support worker; Ignoring record keeping
