The Short Answer
A PIP assessment scores what you can do reliably against twelve activities, not how ill you are. GOV.UK states that for each task the DWP looks at whether you can do it safely, how long it takes, and whether you need help from a person or extra equipment. The appointment usually takes 1 hour and can be at a centre, at home, by phone or by video. Preparing means being able to describe an ordinary day accurately.
What the Assessment Is For
To establish what you can do reliably, activity by activity. The health professional does not diagnose, treat or second-guess your consultant. Their report describes function against the same twelve activities the PIP assessment is scored on, and a DWP decision maker then applies the descriptors.
GOV.UK states what the appointment covers: how your condition affects your daily living and mobility tasks, and "any treatments you've had or will have". It adds that "they might ask you to do some simple movements to show how you manage some activities".

The Four Reliability Tests
Every descriptor is read through four questions, and all four must be satisfied. Regulation 4 of the PIP Regulations sets them out: an activity counts as done only where it can be done safely, to an acceptable standard, repeatedly, and within a reasonable time period.
- Safely — without a risk of harm to you or anyone else. Cooking with a hob after a seizure, or bathing alone with a fall risk, engages this test.
- To an acceptable standard — the task actually completed, not approximated. A meal of the kind the descriptor describes, clothes fastened, a body washed.
- Repeatedly — as often as the activity is reasonably needed. The assessment guide names pain, discomfort, breathlessness, fatigue and anxiety as symptoms that bear on this.
- In a reasonable time period — commonly understood as no more than twice the time a person without the condition would take.
An activity that fails any one of the four is not done to the standard the descriptor requires, and the next descriptor up applies instead.
What to Prepare
Four things, none of which takes long. The purpose is accuracy under pressure, not performance, and GOV.UK states that the appointment "usually takes 1 hour".
- A copy of your PIP2 form. The assessment follows the same activities, and being able to check what you already said prevents accidental contradictions.
- A medication list. A repeat prescription printout answers the therapy and medication questions without recall.
- The aids you use. A list, or the items themselves. Aids are scoring evidence, and the ones used automatically are the ones most often forgotten.
- A typical-day account. Written down, activity by activity, before the appointment.
Describing a Typical Day
Neither your best day nor your worst one. The frequency test asks about more than half the days, so a typical day is the one that decides the score.
The pattern that works is short and factual: what happens when you attempt the task, what help is involved, how long it takes, and what follows. "I can shower, but I need the grab rail to get in, and I sit down for twenty minutes afterwards" answers washing more usefully than either "I manage" or "I can't wash".
Answer what is asked, and add the qualifier if there is one. "Can you walk to the shop?" answered "yes" reads as full mobility; answered "yes, about 30 metres, then I stop, and I could not do it twice" answers the descriptor.
Common Misreadings
The three that cost the most points are all about scope. Each concerns the gap between one hour observed and the more-than-half-of-days test the regulations apply. They come up in almost every refused claim.
Arriving unaccompanied and sitting through an hour without visible distress is recorded as observed behaviour. It is not disqualifying, but it is worth saying what the day cost — that someone drove you, that you will sleep afterwards.
Answering about your best week because you want to be fair understates the ordinary case. The assessment already accounts for variation through the majority-of-days rule, so describing the ordinary case is the accurate answer rather than the pessimistic one.
Assuming a condition with no visible sign will not be believed leads to under-description. What is scored is your account of function, weighed against the evidence — and the evidence you send is what supports it.
What Happens on the Day
The questions follow the twelve activities, one at a time. GOV.UK states that the assessment covers how your condition affects your daily living and mobility tasks and "any treatments you've had or will have". The specific questions asked, and what each is testing, are set out on the assessment questions page.
If you cannot attend, contact the assessment provider using the details in your invitation letter before the appointment. A rearranged appointment delays a claim; a missed appointment without contact can end it.
