The principal of a Philadelphia high school plagued by violence against Asian students has resigned amid questions over her certification.
LaGreta Brown had been principal at South Philadelphia High School for less than a year.
The Pennsylvania Department of Education says Brown holds a state principal certificate, but that it is currently inactive.
The district says Brown had agreed to resign after the end of the school year, but decided to leave Thursday after The Philadelphia Inquirer raised questions about her certification.
Brown says the controversy was impeding the educational process.
Her time at the school leader was memorialized in a scathing editorial cartoon in the Philadelphia Inquirer that depicted Brown sleeping on the job and a series of investigative reports the paper did about a failure of leadership on the day Asian students were attacked at the school.
"How dare anyone portray me as sleeping, clueless, or in any other word knocked out," Brown said at a School Reform Commission meeting after the "Nap Time" cartoon ran.
Otis D. Hackney III, currently the principal of Springfield Township High School, will succeed Brown after a retired principal first serves on an interim basis.
In December, seven Asian students were taken to hospitals after a series of racial attacks at the school.
