Pedro Martinez, who led a significant transformation of San Antonio ISD as its superintendent, has been hired as CEO of Chicago Public Schools. Martinez’s pending departure was confirmed Wednesday by the mayor of Chicago.  Martinez said in his statement, “I will always care deeply about San Antonio ISD. Although I’m leaving with a heavy heart, I know this district will not skip a beat in its pursuit of excellence on behalf of our children. The strongest organizations are those that are built to outlive us – to be sustainable beyond the current leadership. And SAISD clearly has the depth of talent and skill to move gracefully forward.”
