This three-month investigation employed hidden cameras, undercover aids, extensive reporting and interviews to expose a network of "special schools" that thousands of foster children are sent to in California every year. Many of these so-called schools are set up in converted motels and run down strip malls. There are seldom any credentialed teachers in the classrooms; few textbooks and the students are basically warehoused without receiving an education. At the same time, theses schools receive $25,000 to $45,000 per year per student from the state. Compare this to the $6,500 that public schools receive for the each kid. Thousands of foster children graduate without ever having written a book report, term paper or even read a book. Many experts the news team consulted believe this is a big reason one out of every four of the homeless in California are former foster children.
