NEW YORK, NY April 29, 2008 —The group says a study commissioned by the teachers union backs their claim. City Comptroller Bill Thompson says he'll review how the Education Department spent state funds.

WNYC's Elaine Rivera reports.

Of the 390 public schools that received funding to reduce class size, less than half managed to create classrooms of 25 students or less.

Randi Weingarten, president of the United Federation of Teachers, says she wants Thompson to review how the Department of Education spent $153 million of state funding and monitor the additional money schools are expected to get next year.

WEINGARTEN: We are asking him to do a review of both what was done last year and the monitoring so that the city cannot use the new money that we worked for to get it to kids to mask their own inability to keep their promises.

A DOE spokeswoman says the report is flawed. She says class sizes have been reduced and she criticized the union saying some teachers only teach 1 class a day.
