NEW YORK, NY April 15, 2008 —As the housing boom explodes in Manhattan, parents, educators and elected officials say the city is not doing enough to build more public schools in the borough.

A report released by the Manhattan borough president's office shows that elementary and middle schools already face a shortage of 3,900 seats. The Department of Education has plans to add 4,300 seats over the next five years. But critics say it's not enough, especially with so many new buildings under construction.

Parent Julie Mallin has two children at P.S. 199 on the Upper West Side. She says the number of kindergarten classes has doubled in the last eight years.

MALLIN: The time to build new schools is while the residential buildings are still going up not after the schools become overcrowded as a result of those new buildings.

REPORTER: An Education Department spokeswoman says current growth projections are now under review and a revised plan will be released later this year.
