Historically, Class Size has been reported in a number of different places. From 1997 to 2006, it was part of the Database Initiative (DBI) reports (now
archived). From 2002-03 to 2011-12, Elementary Class Size was reported on
School and District Report Cards (archived prior to 2012-13). In 2012, the
statute governing school and district report cards was amended, and Class Size was removed as a required element of the school and district report cards. Also in 2012-13, the
Class Size collection, which was an aggregate collection containing, by classroom and class period, the total number of male and female students enrolled in elementary self-contained classes on a single day, was retired.
In 2010-11, the
Class Roster collection was created. The collection includes more detailed course data than its predecessor, the Class Size collection. Initially, this collection included only reading and mathematics courses in grades 3-8 and 11, but in 2013-14, it was expanded to include all instructional courses. Also in 2013,
HB 2644 established class size reporting requirements for the Oregon Department of Education. In 2014-15, the Class Roster collection was expanded with new data elements to facilitate this reporting, and the OAR governing Class Size reporting (OAR 581-002-0200) was adopted by the
State Board of Education.
In 2014-15, the Oregon Department of Education began producing and reporting class size data for all core subjects.
