By law, nothing has to be disclosed because it's a personnel matter, district spokeswoman Laura Boss said.
Paul Reed, deputy superintendent of business and chief business official, will be in charge of the daily operations in Hubbard's absence for the next four days, Boss said.
Reed assumed those duties earlier in the evening by swearing in incumbents Yelsey, Walt Davenport and Judy Franco, along with the board's newest member, Katrina Foley, who served six years on the Costa Mesa City Council.
Last week, Hubbard was charged with two felony counts of misappropriating public funds when he allegedly gave an unauthorized stipend of $20,000 to Karen Anne Christiansen, 52, the director of planning and facilities, while they worked at the Beverly Hills school district. He also allegedly gave her an increase in her car allowance.
Both measures were not approved by the school board, according to the criminal complaint.
If convicted of the felonies, Hubbard, 53, faces five years in prison, but there's a chance he could also receive probation and be ordered to pay restitution if he has no previous criminal background, said Jane Robison, a spokeswoman for the Los Angeles district attorney.
In an interview last week, Yelsey said the seven-member board planned to listen to Covert's advice on what to do with regard to Hubbard. Yelsey said Hubbard could be placed on administrative leave or would continue to assume his superintendent position in what she referred to as "business as usual."
Hubbard, who was hired by the school board in July 2006, earns between $280,000 and $300,000 a year, according to Reed.
