Chicago’s education watchdog is calling on the city’s public school system to address rising cases of sexual misconduct between adults and students, citing a high number of complaints and telling the system to implement more training for third-party employees.

The Chicago Public Schools’ Office of the Inspector General released a report on Tuesday detailing that the watchdog received 2,075 total complaints spanning several topics, up from 1,825 received the previous year. The office investigated about a third of the complaints, or around 685, the report stated via the Chicago Tribune.
