How are IQ tests considered racially biased?

I live in California and there is a law that African American students are not to be IQ tested from 1979. There is an effort to have this overturned, but the original plaintiffs are trying to keep the law in place. What types of questions would be considered racially biased? I've never taken an IQ test.

Truth be told, they aren't racially biased.  They're socioeconomically biased.  Children raised in a stable middle class home who don't have any mental disorders score significantly better than children who are raised in a lower class home that may or may not be unstable, especially if they have any kind of mental disorder.  Black children are much more likely to be raised in a lower class home, ergo, black children generally score a little lower on IQ tests than white middle class children do.

It isn't because they're dumb, it's a socioeconomic thing.  Black families, on average, earn less than white families.  Also there are a lot more (percentage wise) single parent black homes than there are single parent white homes.

Of course, this doesn't apply to just blacks.  It applies to every child in a lower class home:  They'll generally score a little lower on IQ tests.
