Grasmick is the longest-serving appointed schools chief in the country, according to the Associated Press. She was first named superintendent in 1991 by then governor William Donald Schaefer. Grasmick, 72, announced earlier this year she'd be retiring, saying she wanted to see more of her family and do work that would allow her more flexibility with her time.
Her last day will be tomorrow. More than 700 people are expected to attend a reception tonight in Baltimore County to honor Grasmick.
Earlier this month, the state Board of Education chose former Queen Anne's County schools superintendent Bernard Sadusky to be interim superintendent.
