Smaller classes have been linked to better student outcomes in every way that can be measured • Better grades, better test scores, more engaged and less likely be disruptive when they’re provided with smaller classes. • Students randomly assigned to smaller classes are more likely to graduate from HS in 4 years, go onto college, get a STEM degree, own their own home and have a 401 K 3 more than 20 years later. • Most importantly, small classes are one of only a handful of reforms that narrows the achievement gap between economic & racial groups and thus are essential for true equity in the NYC public schools.

What these class size averages do not show • There are extreme disparities in class size across NYC neighborhoods and districts, with many students in classes of 30 or more. • The number of students in very large classes has grown sharply since 2007 especially in K 3.

Citywide at least 336, 165 students are in very large classes of 30 or more in fall 2018 (14% of K-3 students, 36% of 4 th-8 th gr students & 57% of all HS students) 336 165 182 425 115 903 37 837 K-3 Grade 4 -8 High School (Minimum) Total

What should we do? • We are advocating that $100 M in next year’s city budget be allocated specifically towards reducing class size, starting first in the early grades and at struggling schools. This is less than 1% of total DOE budget. • That would allow the hiring of 1, 000 new teachers, which could lower class size in as many as 4, 000 classrooms – as adding a new teacher at a grade level lowers class size for other students in that same grade. • We also need an accelerated capital plan. Right now 50, 000 of the 57, 000 seats in the new five-year capital plan aren’t proposed to be finished until 2024 or later.
