Working directly with chair Dame Denise Platt, Moore joins ahead of wide-ranging reform. The social services regulator is to be partly merged with Ofsted, to form a single children's services inspectorate, by 2008. The focus for the CSCI is to ensure its services are prioritised in the new inspectorate.
If its functions are not adequately transferred and managed, vulnerable children will be put at 'significant risk', it claims.
Other services will be merged with the Healthcare Commission to form an inspectorate for social care and health.
The Government wants to cut the number of commissions from nine to four.
'We are trying to sort out what form the new commission will take and to ensure that the work we do is continued,' said CSCI external and internal comms manager Andy Keast-Marriott.
Moore said: 'I have a strong interest in the social care agenda, particularly with all the reforms that are emerging.'
Before CancerBACUP, Moore was a health policy analyst at the Parliamentary Information Unit.
She replaces interim comms adviser Dee Sullivan, the former Clare Short adviser who joined Grant Riches Communications as assistant director in June (PRWeek, 17 June).
