As President Donald Trump has threatened to dissolve the U.S. Department of Education, the potential ramifications have left education officials in Southern California concerned about funding.

Trump, who kicked off his second term with a flurry of executive actions, has said he would like to close the department “immediately.”

Shuttering the Department of Education — which provides federal assistance in education — has long been floated by conservatives. Linda McMahon, Trump’s pick to lead the department, suggested during her confirmation hearing moving some of the department’s programs to other agencies, such as transferring enforcement of the Individuals with Disabilities Education Act to the Department of Health and Human Services.

What exactly would be cut from the department — and exactly how it could be dismantled — is still unclear. But already, Southern California education officials say they are concerned about what the future of education will look like without the federal department — particularly when it comes to funding.

Federal funds distributed by the Department of Education don’t make up a lot of local districts’ budgets. For example, only 5% of Santa Ana Unified’s budget comes from federal funds distributed by the department, said Ron Hacker, the district’s associate superintendent.
