Caranza is not opposed to streaming. What he is opposed to is racial segregation of students, where the driving factor behind the segregation is socially driven, irrespective of student ability. In his district, blacks and Latinos are underrepresented in high ability programs, despite research indicating that their population prevalence is statistically indistinct from that of other races. That’s a problem of racism, not appropriate streaming.

Racial de-segregation of schools, overlaid with comprehensive and race-blind gifted ID, is the solution. Pretending racism doesn’t exist and extolling “choice” is not a workable solution, just a tacit nod to self-serving racism.

What is to give light must endure burning.
