世界上最昂贵的学校开学了

Classes began at the world's most expensive public school which costs California taxpayers really a pretty penny. The price tag: a record $578 million.

And despite that unbelievable cost, educators are defending the money spent on the Robert F. Kennedy community school. Melissa McBrian reports now from Los Angeles.

Good morning.

Good morning.

Students arriving at R.F. Kennedy schools are making history where history was made 42 years ago. The 24-acre site was once Ambassador Hotel where Robert F. Kennedy was assassinated during his run for the White House. The campus comprised of 6 pilot schools is the most expensive public school in the country.

I think it's gonna be like more respectful and more learning, wanting to learn, to be successful and it's great in everything.

R.F.K. has a $578 million price tag paid for by voter approved construction bonds. The legendary Cocoanut Grove nightclub in the old hotel is now a theater. The ballroom is now a library. The schools of the complex have soccer fields, swimming pools, art work on display and a park that's open to the public.

A building in the heart of LA is a little different. Building on a historically significant location is a little different. And so $578 million is a significant investment,and it's very well spent.

The students attending R.F.K. are from a 9-block radius. So freshman Jonathan Planco can walk to school with his family, a nice change of pace after riding the bus to Brownwood for middle school.

It's like an hour way. It's now closer to your home. And I don't have to wake up so early.

R.F.K. is already a source of pride in the community. But looks aside, parents say what matters most is what happens in the classroom.

Whatever they are doing here. It'll work in the brains of the children and they won't tear up the surroundings because it's very nice here.

Now R.F.K schools are now home to about 4,200 students. And by openning these doors, the LA USD says that will help alleviate some of the over crowding at other schools.
