Is it possible to categorize assessmen t results by utilizing the attributes in the token table assigned to each token? How about extending User Group features into Survey Results / token entries.

Since assessment results are not stored at the database but calculated at runtime, this isn't possible.

But you can use the Expression Manager to calculate assessment results and store them at an equation question.
You can even use several equation questions for different user groups and store or sum up results for different groups this way.

Thank you once again for your response. Okay I am sold on expression manager! So I will explore this next. Equation question is something you add in the survey but hide it? I can see where this is where you can sum and average numerical responses. Where would you store them? A new table? or is the equation question the field where results are stored? If so, This can / is exported with the answer data?
