Anthony Vazquez/Sun-Times Students in one-third of Chicago Public Schools K-8 classrooms returned to in-person learning over the past month with one key element missing — a teacher. And that learning condition — sitting in a classroom while an educator teaches remotely — was more frequent in majority Black and majority Latino schools than in majority white schools. Those were among the findings of a survey of school leaders conducted by the Chicago Principals and Administrators Association and released this week. Administrators at 195 of CPS’ 415 elementary schools responded, said CPAA President Troy LaRaviere, who pointed to the racial disparity as evidence the district’s reopening plan is hurting even those students of color who resumed in-person learning.
