Yes, prompting and supervision are woolly words!
I think the actual PIP descriptor terms are terrible, it seems like lots of people could fall between two descriptors. I think they should overhaul the wording first.
With regards to the “simple meal” that basically means putting a ready meal in a microwave.
We had to think this through with a relative who was desperate to be independent.
Does she know when mealtimes are? No, but we can set an alarm/phone and prompt for that.
Can she physically take the food out of the fridge or freezer? Yes
Can she check the use by date? No, she can’t read. So that would need supervision so she doesn’t eat mouldy food. But if we put it all in the freezer not the fridge, we only need to check rarely.
Can she remember to pierce the film? Might need prompting for that at first but can probably learn.
Can she physically put the food into the microwave? Yes
Can she check the cooking instructions and turn microwave to the correct time and power? No, she can’t read. Can someone prompt her? No, she can’t read the microwave display either.
No way round that one, someone will have to go in for mealtimes to supervise.
