Mayor Michael R. Bloomberg and Schools Chancellor Dennis Walcott announced the city's plan  to open 54 new schools this fall, including a high school academy for software engineering. Come September, the Bloomberg administration will have closed 140 schools and opened 589 new ones since 2002, through a longstanding policy that has set out to replace poorly performing schools. The new schools will eventually serve more than 21,000 students.
