OAKLAND -- The prospect of losing $4.3 million in education funding next year -- as Gov. Arnold Schwarzenegger has proposed -- has rattled districts statewide.

But even as school leaders scour their budgets for potential cutbacks, they are mobilizing to stop those cuts from happening.

On Wednesday, superintendents from every Alameda County school district, as well as from the county's Office of Education, will convene at Oakland's Westlake Middle School to urge Schwarzenegger to reconsider his proposal.

"Governor, you're breaking our hearts!" is the message they intend to send at the news conference, the eve of Valentine's Day.

"This is very, very unhealthy," said Sheila Jordan, Alameda County's superintendent of schools. "You can't just talk about education and not fund it."

Last month, Schwarzenegger proposed making 10 percent cuts to education and other departments, including state parks and prisons, in 2008-09 as a solution to the state's multibillion dollar budget deficit.

Elizabeth Hill, the state's legislative analyst, has issued a report critical of the across-the-board reduction approach to fiscal solvency. She suggested that lawmakers prioritize programs and reconsider some of the existing tax credits and loopholes.

The news conference will take place at 9:45 a.m. Wednesday at Westlake Middle School, 2629 Harrison St., Oakland.
