Chicago Public Schools, the biggest school district in Illinois and third in the U.S. with 638 schools and 341,000 students, has already been planning for a mostly in-person fall. CEO Janice Jackson, who is leaving CPS in June, said earlier in May that CPS was “looking to the state … to get us back to normal from a schooling perspective where everyone is expected to go to school in a brick-and-mortar building every single day unless there are extenuating circumstances, medical circumstances, that prevent them from coming to school.”
