From The Arizona Daily Star: The Tucson Unified School District is considering staffing cutbacks that could leave some schools with part-time principals. School site councils have until April 30 to decide how to adapt to budget cuts of up to 18 percent, whether it means shuttering libraries, losing counselors or cutting back on administrative positions. Some are poised to scale back on vice principals. Others are looking at half-time principals. Some may even choose to have no principal, if they can come up with a way to ensure duties typically carried out by principals are still completed.
