LOS ANGELES – Next month’s opening of the Robert F. Kennedy Community Schools will be auspicious for a reason other than its both storied and infamous history as the former Ambassador Hotel, where the Democratic presidential contender was assassinated in 1968.

With an eye-popping price tag of $578 million, it will mark the inauguration of the nation’s most expensive public school ever. The K-12 complex to house 4,200 students has raised eyebrows across the country as the creme de la creme of “Taj Mahal” schools, $100 million-plus campuses boasting both architectural panache and deluxe amenities.

“There’s no more of the old, windowless cinderblock schools of the ’70s where kids felt, ‘Oh, back to jail,'” said Joe Agron, editor-in-chief of American School & University, a school construction journal. “Districts want a showpiece for the community, a really impressive environment for learning.” Not everyone is similarly enthusiastic.

“New buildings are nice, but when they’re run by the same people who’ve given us a 50 percent dropout rate, they’re a big waste of taxpayer money,” said Ben Austin, executive director of Parent Revolution who sits on the California Board of Education. “Parents aren’t fooled.” At RFK, the features include fine art murals and a marble memorial depicting the complex’s namesake, a manicured public park, a state-of-the-art swimming pool and preservation of pieces of the original hotel.

Partly by circumstance and partly by design, the Los Angeles Unified School District has emerged as the mogul of Taj Mahals. The RFK complex follows on the heels of two other LA schools among the nation’s costliest — the $377 million Edward R. Roybal Learning Center, which opened in 2008, and the $232 million Visual and Performing Arts High School that debuted in 2009.

If I lived in California…I think I would just leave.
