LOS ANGELES, Calif. (KTLA) -- Facing a half-billion-dollar deficit, the Los Angeles Unified School District is facing deep cuts and parents, teachers and students demonstrated Tuesday in response, hoping to save key programs.

Thousands of protestors chanted almost all day outside the district building in downtown Los Angeles, hopeful their voices could rescue some of the programs from the chopping block.

Adult eduction and arts programs are among those that could be cut as the district deals with a massive budget shortfall. Inside the LAUSD Board of Education's Tuesday meeting, parents and students shared how the programs impacted their lives.

Famed choreographer Debbie Allen and Guns 'n' Roses drummer Matt Sorum were among those who spoke out in support of the endangered programs.

"We're in one of the greatest entertainment communities in the world," Sorum told KTLA. "It just looks bad (to cut arts programs)."

The board did not make any decisions Tuesday on plan to slash the budget. Members laid the need for the cuts on Sacramento for not making education a priority.

California ranks near the bottom nationally in state funding.

As many as 7,500 layoff notices could be issued to teachers and staff members if the school board follows through with adoption a proposed list of cuts.

For now, district officials are looking for other revenue streams and will continue talks with bargaining unions to try and avoid the layoffs.

"The hope is that there can be a shared solution that we don't have a fifth year of destruction of school communities," said Warren Fletcher, president of United Teachers Los Angeles, the union representing the city's educators.
