Let's assume that there is an intelligence threshhold for teaching: an IQ of 115 or higher.
Let's further assume that the GenPop is 12% Black.
For white people, a 115 IQ is one standard deviation above the mean. Hence, we know that approximately 16% of the white population could be a teacher. But for Black people, a 115 IQ is TWO standard deviations above the mean, which means that only 2% (roughly) of the 12% has the threshhold intelligence to cut it - 0.24% of the overall population. To repeat, one sixth of the white population meet the cut, but only 1/50th of the Black population will make it. Which explains why in areas where we do have significan numbers of Black teachers, so many of them are sub-par. California's attempts to test and prequalify teachers have been a complete fiasco, due to the horrible scores achieved by the Black and Hispanic test-takers.
Now add to that situation the fact that super-intelligent Blacks have so may other opportunities, what with Diversity being emphasized in government, Academe (higher education), and in the corporate world.
More Black teachers? Expect a combination of unmet targets and substandard hires.
