Clickable NYC school overcrowding map

The Campaign for Fiscal Equity, the organization that successfully sued New York State, for more funds for New York City schools,
has launched an interactive, clickable map, at a site called, overcrowdednycschools.org.

Enter qualifiers or search limiters, such as borough, district or elementary or high school, and you can see the degree of general overcrowding and trailer siting of classes.

Once you survey the results and find them objectionable, you can then click the "Take Action" tab, leading to links for contacting public officials.
