Chicago Public Schools officials denied wrongdoing Friday after a change in their COVID-19 case tracking, made around the time of the district’s dispute with the Chicago Teachers Union, caused confusion and transparency concerns.
The problems came to light only after an independent data observer pointed out this week that discrepancies in the district’s figures made the number of infections at individual schools appear lower than was actually the case. That, in turn, prompted worries that parents might not have up-to-date information.
