The campus of York Castle High School in Brown's Town, Jamaica, is nothing like that of St. Paul Academy and Summit School in Highland Park. In Brown's Town, garage-like classrooms of concrete block are clustered behind a ragged main building.
Students sit in decades-old desks.
A single grassy area serves as the school's athletic fields. Cows and goats roam nearby. Until two years ago, the school had four outdated computers. That changed when SPA math instructor George Leiter helped deliver three modern PCs to the 400-member student body. Last winter, he brought in 17 more and set up a computer lab.
