Racism in US teachers is in fact a big problem, as is racism among doctors and bankers[1]. And focusing on standardized test scores almost always hurts poor students because it rewards families who can afford private test preparation[2]. These are scientific facts with a great deal of evidence - evidence which is considerably more compelling than “it sounds good to Hacker News.”

You are just wrong. You cannot just make things up because they are ideologically convenient. And I am so sick of having the same zombie arguments with people who are recklessly indifferent to the facts at hand.

> In this sample, we found no significant association between occupation and level of bias (see Table 4). That is, teachers held levels of implicit bias, explicit bias as operationalized using a feel- ing thermometer, and symbolic racism that were not statistically different from the levels of nonteachers. This result persisted through all five models. That is, this lack of relationship held despite controlling for demographic factors (Model 2), educa- tion (Model 3), political preference (Model 4), or all of these characteristics combined (Model 5).

> In conclusion, we have found that teachers’ [anti-Black and pro-White] bias levels are quite similar to those of the larger population. These findings challenge the notion that teachers might be uniquely equipped to instill positive racial attitudes in children or bring about racial justice, instead indicating that teachers need just as much sup- port in contending with their biases as the population at large.

> Researchers, including those who work for the test companies, have known wealth is strongly correlated with outcomes on standardized tests for years. There are several reasons why. Wealthy students attend higher ranked schools within more financially resourced districts. Richer families can afford more tutoring, test prep and enrichment activities. The College Board never claimed that test prep could improve scores until it was available for free online, at which point the evidence of improvement came rolling in. Standardized tests are better proxies for how many opportunities a student has been afforded than they are predictors for students’ potential. Consequently, tests weed out budding low-income students instead of creating equitable access to institutions that help build wealth. This is why many colleges have abandoned using standardized test altogether.
