Should Chinese Speaking Students get credit for AP Chinese?

The actual question was Should Spanish-speaking students get credit for doing well in AP Spanish in the Washington Post, but it's a good question for the Chinese AP.

Just as with the Chinese SAT II - do native Chinese speakers have an unfair advantage?

My thought is no, but it helps on the Chinese SAT II if you get the right study material so if you are a native Chinese speaker, you get a high score. I did appreciate the point made in the comments that just because you speak a language, does not mean you have a good understanding of the rules of grammar and such. That is especially true in English, which has all sorts of inconsistent grammar, pronunciation, and spelling rules (the challenge of a language that continually borrows from other languages).
