Two things,

1) Please confirm if the mean is 100 and SD is 15 for this testing.

2) I was reading this document

http://www.prufrock.com/Assets/ClientPages/pdfs/sages/CH06-SAGES-2.pdf

and found that the mean and SD values are different for different ethnic groups to incorporate the fact that you had mentioned. However, I don't find the 'Asian' ethnic category there.
