The Department of Education says that school suspension rates spiked during the first half of this school year.
The newest numbers show that from July to December of 2013, more than 22,500 students were suspended.
That's an increase of about 26 percent from the same time period in 2012.
However, since December, the suspension rate has fallen to a little less than a half a percentage point from the same period time last year.
The New York Civil Liberties Union says that the slight drop is a sign of a culture shift in the school system from the Bloomberg administration to the de Blasio administration.
City Council Education Committee Chairman Daniel Dromm says that the numbers haven't changed enough and that the DOE needs to improve its intervention techniques.
