Disparate Impact

The test has been posted online. I’d be curious about your opinion, and an example, of any question which could be construed as being favorable toward one racial background over another. Every test has criticizable features but surely the main consideration should be whether or not it favors any group somehow. While anyone can state that other tests would do a better job, it’s a hollow statement without concrete alternatives. In general what many testing companies have done is to substitute soft evalulations such as oral questions, or other non-quanitified metrics because of the persistent disparity on quantified, standardized tests. And while it may well be the case that such tests are inadequate, there remains the issue of explaining away why an inadequate test would produce disparate impact if no race-based biasing is present. An inadequate test is equally inadequate for all.

Simply criticizing the test in general does not address the key issue. Moreover, the key sticking point of current disparate impact law is that the test for whether or not a test is biased is disparate outcome. Disparate outcome alone is sufficient to question the test itself.

“…an adverse impact if members of a protected class are selected at a rates less than four fifths (80 percent) of that of another group. For example, if 50 percent of white applicants receive a passing score on a test, but only 30 percent of African-Americans pass, the relevant ratio would be 30/50, or 60 percent, which would violate the 80 percent rule.” EEO Information and resources for HR Professionals and Students

Such a rule only makes sense if there is an a priori assumption that the cohorts being compared are equal in potential to pass the test.
