NEWARK - The Robert Treat Academy Charter School in Newark scores much higher on tests than the city's regular public schools, even though it spends less on each student than public schools do. The statistics have some skeptical that a $100 million donation from the founder of Facebook will help turn the troubled school district around.

Robert Treat Academy spends $13,000 a student, about half that the rest of the schools in the district spends.

The school is a kindergarten through eighth-grade public school, with around 400 students, selected by lottery. The school year runs from early August through June, a month longer than other schools. Many students also attend Saturday classes.

There are around 40,000 students enrolled in Newark public schools overall.
