The sanitation civil-service exam thrown out because of suspected cheating cost the city at least $1.2 million, the Post has learned.
The Sanitation Department spent $621,000 to pay some 2,300 workers a day’s salary for taking the supervisors’ exam on April 13.
And it spent $565,000 in overtime for workers filling in for the test-takers, said spokeswoman Belinda Mager.
Last Monday the city notified candidates that all of the scores were invalidated.
Officials had learned the questions and answers had been stolen and widely distributed on the Internet.
The city Department of Investigation is now probing how the breach occurred — and who is responsible, officials said.
The DOI is also probing whether an upcoming May 11 sanitation exam, for “promotion to general superintendent,” was also corrupted. The DOI says anyone who breached test security could be fired and prosecuted
Staten Island City Councilman Joseph Borelli, said the scandal could be the tip of the iceberg.
“This calls into question our entire civil service system if we can’t guarantee that tests are fairly administered,” Borelli said.
