The El Camino Real Charter High School was a successful public high school; in 2011, it converted to charter status, and it is now a successful charter school.

But it has a big problem. Its principal and other top employees charged many thousands of dollars to the school’s credit card for expensive dinners, luxury hotels, and first-class air travel while moonlighting as a scout for a professional basketball team.

The school has been warned repeatedly, and now the school board is giving it one month to clean up the mess.

The case is one more example of tensions between the nation’s second-largest school system and its charter schools, which manage their own public funding and are free from some rules that govern traditional campuses. El Camino Real Charter High School was run by the district until 2011.

At last week’s meeting, board member Scott Schmerelson said El Camino as a charter remains “an excellent school.”

But it “is not a private school,” said Schmerelson, who represents the west San Fernando Valley area where the school is located. “It is a public school. They have to go by the same rules we do.”

The El Camino case could test the limits of that assertion. El Camino, for example, has declined to tell the district whether it has taken disciplinary action against Executive Director Dave Fehte, who has come under internal and external scrutiny. Such action could be considered a confidential personnel matter, to be kept even from L.A. Unified.

A report from the district’s charter school division accuses El Camino of demonstrating “an inability to determine how public funds are being used,” adding that “fatal flaws in judgment … call into serious question the organization’s ability to successfully implement the charter in accordance with applicable law and district requirements.”

According to L.A. Unified, a sampling of 425 credit card expenses from five El Camino employees, including Fehte, revealed that “countless expenses were incurred without adherence to any uniform procedure, and without verification of the necessary details.”

Apparently the charter school board thought that the school’s autonomy extended to its financial affairs. We will watch what happens.

Is it a public school or a publicly funded private school?
