Yes,the assessor and care co-ordinator can be the same person, as long as they are a registered health or care professional, but there should always be at least two assessors and ideally would involve all the multi disciplinary team. It is always better that the assessor is someone who knows the person but this is not always possible if the assessment takes place in an acute hospital situation, as is often the case, but family and any other interested parties should be asked to contribute as well. There is always the option to challenge or appeal against a decision and ask for a full assessment (DST) to be completed even if the checklist does not indicate this. Checklists are not always to be relied upon as an accurate reflection of the situation, which can change from day to day. This link might help.
