"Even if you fail the first time, the majority will get it on appeal. Just edited to say those I assisted had medical evidence of their ailments and prescriptions, not just a form."
That's a real 2+2 equals 5 statement. PIP isn't hard to claim if you understand the intent and scope of each descriptor, know the 4 conditionality criteria (safely, to an acceptable standard, repeatedly, and timely), are reporting accurately, and have medical evidence. All 3 of my children get the enhanced rate of PIP, and they all got it based on our application form and the medical evidence I supplied, without being assessed either by telephone, video or face to face. I recognise that I am privileged to have the intelligence and mental resources to be able to find, investigate, and digest the help and information that is available on the internet. I recognise that I am privileged that I have good communication skills so can explain their difficulties in a way that is clear, logical, and accurate. I recognise the 'double benefit' effect of the fact that I was able to use those skills to get them the Educational Health and Care Needs assessments they needed (alongside invaluable support from a poster on MN who gives tirelessly patient guidance), which meant that they have the specialist education they need, and all the assessments that reveal the extent of their needs, which in turn provides evidence to the DWP. In short, it was 'easy' to apply for PIP because the assessor could see clearly which points to award, and they had multiple different pieces of evidence that all said the same thing from slightly different angles.
Initial assessments often aren't easy to apply for because people don't realise what the questions are asking. For example, that when they are asked about cooking, the question is about cooking a simple meal for one person, with all the ingredients available, with all the aids that could reasonably be expected, and doesn't take into account real life. They don't care if you can't lift the heavy pan of boiling water. They don't care if you can't bend down to an oven. They don't care if you chop 10 carrots for your family, but get tired and are in pain after chopping 4 carrots, because one person would only need 2.
Assessments by claims assessors are looking to test the claim of the claimant. Someone that says they 'can't multitask' without explaining what that means, but then drives themselves to an assessment centre, is likely to be seen to contradict themselves. If they had understood that, they might have gone in to more detail about why tasks in the house allow them to get more distracted by external stimuli and competing demands, versus the multitasking that comes from pushing a pedal, steering a wheel, and observing the environment, but is all focused towards one goal and activity.
When they get to tribunal, the panel is trying to establish if the decision of the assessor is correct in light of the available evidence, and the claimant themselves is part of the evidence. So when they say 'You say you can't multitask but the assessor says you drive and that's multitasking', the claimant can say 'I meant that when I'm trying to do things at home I get distracted. So I start to make lunch, but then I notice some washing up that needs to be done so I start to fill the sink, then I forget that I've put food under the grill, until the smoke alarm goes off, then I turn around and the sink is overflowing, but the telephone rings and I'm in a complete mess. It takes so long to clean up that I'm exhausted and then I can't do x,y,z that I should be doing. When I'm driving, I'm trying to get from A to B, and everything I'm doing is focused on getting there safely. I have my phone turned off so it can't ring. I don't use the radio because it's distracting. I find driving stressful but the fact that I'm in the car on my own means I can use all of my energy to concentrate on driving.' This clears up the apparent contradiction.
Another situation might be 'claimant is not under specialist services for pain, so pain is not significant'. At tribunal, the claimant might point out that they were under a pain clinic, but moved house six months ago, and that the waiting time for pain clinic in their new area is 17 months.
