Class Size Report

2008-09 Preliminary Class Size Report (updated on 12/12/08)

Excel versions of the 2008-09 Preliminary Class Size Report are posted below. The report includes average class size data at the citywide, borough, district, and school levels. This year, for middle schools that program classes using MSPA, average class size data is reported by core subject as well as by official class. Additionally, to improve accuracy of reporting at the high school level, a process was created to identify classes assumed to be Collaborative Team Teaching (CTT).  New information is included in the reports to indicate where these matched sections were identified.  Please click here for a detailed explanation of the average class size calculation methodology.

A detailed PowerPoint Presentation provides helpful information summarizing and explaining the class size reports. It includes a review of changes made to our reporting format and important notes about the data.

Similar to 2007-08 class size reports, the 2008-09 Preliminary Class Size Report uses a point-in-time “snapshot” of the data and is identical in format and methodology.  In response to public feedback, the data presented in the current report reflects information pulled from the Department of Education’s systems of record on October 31, 2008, whereas the 2007-08 Preliminary Class Size Report was based on data pulled on December 7, 2007.  This change allows for earlier reporting of preliminary class size data, however please note that the register data has not yet been cleaned to account for those students who are no longer in attendance.

School Data

(1) Aggregate School-level Data: This file shows average class sizes for each school, aggregated by grade span (K-3, 4-5, 6-8, 9-12) and program type (General Education and Collaborative Team Teaching (CTT), Self-Contained Special Education). These data are shown by the above grade spans because the maximum allowable class size differs by grade and therefore a single school-level average is not representative of instructional practices. For each grade span and program type, we also provided a breakdown of the total register and number of classes, as well as the largest and smallest class size.
