Class Size Matters is a non-profit, non-partisan clearinghouse for information on class size and the proven benefits of smaller classes. We advocate for class size reduction in NYC, where our students are disadvantaged by having the largest classes in the state and some of the largest in the nation. In addition, we are working to protect the confidential education records of students from being shared with corporations without parental consent, as nine states, including New York, intends to do as part of inBloom, Inc.
