A number of the daily living activities ask whether supervision is needed to satisfy a particular descriptor. Additionally, a person only counts as being able to carry out a daily living or mobility activity unaided if they can do so without supervision.
The meaning of "supervision" is defined in regulations.
Schedule 1 of the main PIP regulations provides -
“supervision” means the continuous presence of another person for the purpose of ensuring [the claimant's] safety;
"unaided” means without - (a) the use of an aid or appliance; or (b) supervision, prompting or assistance.
Commentary: In  UKUT 105 (AAC) a Three Judge Panel ruled that when assessing whether supervision is required, it is necessary to weigh up the likelihood of the harm occurring against the severity of the consequences - it is not necessary to show that the occurrence of harm is 'more likely than not'. | Add commentary or suggest an edit.
