Chicago Mayor Lori Lightfoot is expected to announce on Wednesday that Chicago Public Schools will start the school year with remote learning, according to CPS sources.

Ever since floating a proposal that students go to school buildings two days a week, officials have said they won’t make a final decision until closer to Sept. 8 start of school.

That decision was likely sped up by the threat Tuesday from the Chicago Teachers Union to hold a strike vote next week if the school district went forward with in-person learning.

The announcement also comes amid rising COVID-19 cases in Chicago. The district said a move to remote learning was dependent on whether the Chicago Department of Public Health determined COVID-19 cases weren’t under control. Though the city hasn’t surpassed those benchmarks, there is growing concern Chicago will reach them before too long. .

Now, Chicago parents and teachers will be looking to Chicago Public Schools to put forth a robust remote learning plan.

There’s wide acknowledgment that remote learning was a bumpy experience in the spring when all schools were abruptly shut down. For more than a month, Chicago Public Schools did not have any formal instructional days with some schools offering a lot of lessons and others none.

And even once school was officially in session online, a quarter of students did not log on even once weekly and 16 percent did no graded work, according to CPS data from the week of May 11 through 16.
