I don't even remember the context, but I'm sure it had to do with educational evaluations. I often read the blogs Number 2 Pencil and Joanne Jacobs' blog, which are about standardized tests in education and general education, respectively. I just read a post by Kimberly Swygert relating to "cultural bias" on tests....
...There may indeed be cultural bias in standardized tests, but having seen many versions of the general GRE and the SAT in the 80s, 90s, and today (the recent viewings courtesy of being a short-time employee for Kaplan), these aren't culturally biased tests for what they're testing for (you won't pass the verbal sections if you don't know English, for example, but test-takers know that English language ability is one of the things being tested for.)
How come no one seems to consider the possibility that they don't pass the test because they don't know the material? Say, they don't know how to graph a line given an equation like 3x + 2y = 6? The tests are "biased" against people who know nothing. I doubt this is an ethnic trait.
Don't bitch about the testing -- complain about one's lack of education. If one were given an adequate education and one still failed basic skills/knowledge tests repeatedly.... I wonder who then is at fault? Hmmm?
