Thetis White’s class is diverse—filled with students from different races and backgrounds, who are all taught by a Black man. That’s not uncommon at Monroe Elementary in Brooklyn Park, a diverse suburb of Minneapolis, but it is rare in Minnesota as a whole, where fewer than one percent of teachers are Black men.  Experts say the low number of teachers of color contributes to wide educational disparities in Minnesota. The state has historically ranked near the top in test scores and graduation rates. But those numbers mask wide differences between white and, in particular, Black students.This year, about 52 percent of white students met state standards for math, compared to 18 percent of Black students. And, on reading, 60 percent of white students were proficient, double the percentage of Black students.
