2007-08 Class Size Report (updated on 2/15/08)

Excel versions of the 2007-08 Class Size Report are posted below. The report includes average class size data at the citywide, borough, district, and school levels. Given recent improvements in the course coding for the High Schools Scheduling and Transcripts (HSST) system, the high school (grades 9-12) portion of this year’s class size report is produced using a different methodology from previous years. For this reason, this year’s high school data is not comparable to the high school data posted in last year’s report. 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 report. It includes a review of salient changes to our reporting format, analysis of  class size reductions and important notes about the  data.

The data presented in this report reflect information pulled from the Department of Education’s systems of record on January 23, 2008. The Preliminary 2007-08 Class Size Report was published on this site in December 2007 based on data pulled on December 7, 2007. The current report is identical to the preliminary report in format and methodology; however the data reflects register adjustments and course coding corrections that occurred between December 7, 2007 and January 23, 2008.

Prior years class size reports used a combination of point-in-time “snapshots” and audited register files for reporting depending on grade level and time of year. Beginning with the December 2007 report, we will only use point-in-time snapshots taken shortly before the reporting date. Our annual reporting will happen at the same time each year to allow for comparability.

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.
