PIP points decide the rate, not the diagnosis
PIP is built around activities and descriptors. Points are awarded because of the level of difficulty you have with those activities, not simply because of the name of a condition.
That is why understanding the points system matters so much. It tells you where a claim looks strong, borderline or likely to need better evidence.
The key thresholds are 8 points and 12 points
In each component, 8 points usually means standard rate and 12 points usually means enhanced rate. The components are separate, so you can score enough in one component without qualifying in the other.
This is the reason even a simple checker can be useful. It helps you sense-check the likely band before getting lost in the full assessment language.
Points only matter if the descriptor applies reliably
A point total is only useful if the descriptor genuinely applies most of the time and meets the reliability tests: safely, repeatedly, to an acceptable standard and within a reasonable time.
Use a points guide to orient yourself, but use evidence and examples to make the case stronger.
