Petrina Howard was a proctor during the testing and was interviewed in March by investigators whose report named 180 educators, including 38 principals as participants in cheating, said Michael Bowers, a lead investigator and a former state attorney general.
More than 80 APS employees confessed to cheating, according to the report. The investigators said they uncovered evidence of cheating in 44 of 56 schools they examined.
Legal ethicist David Zarfes said Howard probably isn't obligated to recuse himself when his wife is a minor employee in a large school system. Her employment, however, could give the appearance of a conflict and breed public suspicion, said Zarfes, an associate dean at the University of Chicago law school.
Petrina Howard's role was minor, Bowers said.
"Mr. Howard has been a stand-up and straightforward guy with us," he said.
