"Due to reports of excessive heat throughout Chicago tomorrow, we have determined that it is in the best interest of our students and instructional staff to cancel summer school for the day in non-air conditioned buildings," said CEO Brizard.
The District will continue to monitor the heat wave, and any additional information will be disseminated once those decisions are made. We urge school communities, parents and students to continue to monitor these announcements on television, radio and the CPS web site, www.cps.edu, Facebook and Twitter.
The Chicago Public Schools serves approximately 405,000 students in more than 675 schools. It is the nation's third-largest school system.
