PIP assessments ?
One's that are by the textbook or
those that happen in real life situations ?
Quite a bit on the Internet for both ... especially the latter as maybe sort from the disability organisations forums ( SCOPE being one of the leading ones for an active forum. )
emotive subject amongst the less abled community !
As for general " What to expect " guidance , a couple of links to the leading players in this field ... SCOPE one complete with a video ... the second from the CAB :

https://www.citizensadvice.org.uk/benef ... ssessment/
Some sail through ... others have no end of problems.
An advocate working with you ?
To be a consideration ... Internet search ... PIP Advocates ... will produce many links ... even your son's own supporting organisation may have such a service ?
Bear in mind the thousands that have PIP assessments every year ... and the actual number reporting the outcome anywhere on the Internet ... perhaps 1 in every 500 or so ... and even then , a bias towards what went wrong ???
Other readers will , hopefully , be along to relate their first hand experiences.
