'Perfection, not speed, is the key goal in medical transcription skills.' can be analyzed for different parts of speech and sentence structure, as often done in English grammar studies.
When breaking down the sentence:
The subject is 'Perfection.'
The verb is 'is.'
The sentence itself represents an independent clause because it can stand alone as a complete thought.
There is no appositive in this sentence.
A parenthetical expression is when additional information is inserted into the sentence as an aside, which is not present here.
