Your comments suggest a reasonably normal assessment.
It's almost impossible to second guess the result of an assessment based on how it went, we have seen the worst assessment result In the highest award and the best score no points whatsoever.
The only thing that I can suggest is that she request a copy of her assessment report by contacting the DWP office dealing with your claim.
