Learn English – A term for an outstanding lawyer

Have you considered using the Dreyfus model of skill acquisition? In particular, his ranking is:

1. Novice
2. Advanced beginner
3. Competent
4. Proficient
5. Expert

Note that each level has a specific, quotable, empirically-driven definition that allows one to (more-or-less) unambiguously identify which category one belongs to.

That might be helpful if your application is a self-survey which is otherwise vulnerable to differences of interpretation: a standard model has the benefit of normalization (to a larger extent than, say, “on a scale of one to ten. . . .”).

That said, since perfect standardization is an impossible ideal, if you implement this, you might consider offering an "other" option.

Alternatively, the word specialist comes to mind.

Net profit is a proper definition or net financial result:

• Often referred to as the bottom line, net profit is calculated by subtracting a company's total expenses from total revenue, thus showing what the company has earned (or lost) in a given period of time (usually one year). also called net income or net earnings.
