Throughout the United States, in every public school where blacks and whites learn together, there is a racial test score gap in which whites perform better on standardized tests than blacks do.

Why?

Well, the people who put together this page,

What Explains White-Black Differences in Average Test Scores?

. . . believe that whites are being given "educational opportunities" that are simultaneously being denied to blacks.

They are vague about the details, however. They never specifically identify which opportunities these are. Also, they never specifically identify the racist meanies who are going around telling black students, "No! You can't have this opportunity because you are BLACK!"

These researchers are either self-deluded or they are duplicitous. There are no "educational opportunities" being denied to blacks, and there are no racist school officials running around all the public school districts in the country enforcing a racial double standard — not one opposed to giving opportunity to blacks, anyway.

The racial test score gap exists because blacks have smaller brains (80 to 100 grams less massive than those of whites) and, as a result, lower intelligence (average IQ 85) as compared with whites (average IQ 100). The reason is biological, not cultural, and therefore it is not remedial by social interventions of any sort.

But apart from that stubborn clinging to the popular, but incorrect, egalitarian explanation, the page does convey some important statistical information regarding the racial test score gap in American public schools.

Leftists claim that the white/black racial test score gap in public schools is the result of whites having "educational opportunities" that blacks don't get. Which opportunities are they talking about? Specifically!? I'd really like to hear a few concrete examples of this, but they never say. This sort of hand-waving should be regarded as suspicious, and the hand-wavers should be called out on it every time.

I haven't checked recently on the per pupil funding for public schools in order to determine whether allocations of tax money could be blamed for the existence of a white/black racial test score gap. But I did check that very thing in 2010, during the CRCT cheating scandal in Georgia, and I found out (among other things) that the heavily black Atlanta Public Schools were funded at a level that was 44% higher than the Georgia state average — and the black kids were performing miserably anyway.
