The district is looking to cut $400-million over the next two years and that is on top of $40-million in cuts proposed for this school year.
It would mean cuts in the central office staff and mandatory unpaid furloughs, just to start.
"You will see layoffs, you will see class sizes go up significantly, you will see [loss of] art, music, athletic programs," Ackerman told members of city council..
Ackerman said the district would also freeze hiring and discretionary spending.
A worst case scenario could see schools closed or consolidated.
These changes are still being discussed as much depends on state and federal aid and how many students enroll in charter schools.
