This week you will learn about test biases. The focus becomes one of the tests being used in an impartial, just, and equitable way. Do we have a bias about the existence of test bias? Test Bias Test bias is a statistical property of a test that involves a deficiency in the test itself, resulting in discrepant scores or meanings, depending on the test taker’s identifiable subgroup. Subsequently, test bias can exist in, and impact, any of the categories of validity that you read about last week. Remember that validity deals with the evidence if a test measures what it purports to measure. If a test yields discrepant meanings for different members of an identified subgroup, then bias may be suspected. As noted above, however, bias can be examined through statistical means. With statistical procedures, publishers of tests can perform appropriate checks for the existence of bias prior to publication. Such procedures now use item selection methods based on either classical test theory (CTT) or item response theory (IRT). Further, consistent with misconceptions you will read about in your Psychological Testing and Assessment text, most well-constructed standardized psychological and educational tests appear to be reasonably unbiased for the subgroups investigated in the research. This is clearly an advancement from much earlier versions of standardized tests. Test Fairness Moving beyond bias, but without ongoing vigilance, we can turn our focus to test fairness. When discussions about a test involve values and differences of opinions about its use across groups based on their opposing points of view, then one is talking about fairness. The focus here becomes whether the test is being used in an impartial, just, and equitable way. Psychometrics has been utilized as a means to prevent or remedy issues of test fairness. Similar to bias, methodologies from CTT or IRT have been employed to deal with this issue. In the discussion for this week, you will discuss how CTT and IRT have made attempts to address issues of test fairness.

I hope I can get this same writer to complete the rough draft and final powerpoint as soon as the teacher posts her instructions. This part was great! Thank you so much.
