After an advisory panel rejected a waiver for Mayor Bloomberg's school's chancellor nominee, a compromise is being floated:

Let Bloomberg's nominee, Cathie Black, act as a general manager, and have her hire a senior administrator steeped in pedagogical issues.

On the Brian Lehrer Show this morning, outgoing chancellor Joel Klein - who got the kind of waiver Bloomberg is seeking for Black - said he hired a top staffer more familiar with education issues than he was.

But Black's critics are knocking down the idea, saying it skirts the system of checks and balances City Hall says they're seeking in schools.

"It would dilute the accountability,"says city comptroller John Liu.
