The statue directs the Oregon Department of Education (ODE) to report information about the total number of students in classes and the total number of licensed or registered teachers regularly assigned to students in kindergarten through grade 12 classes to the Legislative Assembly. This report is due February 1 of each year and covers the prior school year.  \nState level data are shown below, displaying the total number of students and teachers as well as the median size of the classes in each category of class (median is presented rather than mean to better account for skew in the data) . Two types of classes are reported and broken down into subtypes. The first type is a “self-contained” classroom, defined as a classroom where the student spends the majority of their day and receives most of their core content instruction. This classroom is typically the “homeroom” for students in elementary school. The second type is a“departmentalized” classroom where students receive instruction in a particular content area. These classes are most common in middle and high schools where students receive instruction from different teachers throughout the day.  \nMEDIAN CLASS SIZE IN OREGON, 2024-25 SCHOOL YEAR  \n\n| Subject Area Median\u003Cbr>Class Size\u003Cbr>Total Students\u003Cbr>Total\u003Cbr>Teachers |  |  |  |\n| --- | --- | --- | --- |\n| All Subjects/Grades | 23.0 | 521,838 | 24,297 |\n| Total Self-Contained | 22.0 | 238,260 | 10,812 |\n| Kindergarten | 20.0 | 31,63","cbCaivWwm4auFsFQ","https://ap.wps.com/l/cbCaivWwm4auFsFQ","pdf",1042379,53,"English","# Executive Summary\n## Median Class Size in Oregon, 2024-25 School Year\n## 2024-25 Class Size Report for Oregon Public Schools (House Bill 2644, 2013)\n## Background and History\n## Oregon Law\n## Class Roster Task Force\n## Conclusion\n## Appendix A: District Median Class Size, All Subjects, All Grades","[{\"question\":\"What legal requirement drives Oregon’s class size reporting?\",\"answer\":\"House Bill 2644 was passed in 2013 and incorporated as ORS 329.901, directing the Oregon Department of Education to report student and teacher totals and median class sizes for K-12 classes each year to the Legislative Assembly.\"},{\"question\":\"What is the difference between self-contained and departmentalized classrooms in this report?\",\"answer\":\"A self-contained classroom is where students spend most of the day and receive most core content instruction, typically functioning as a homeroom in elementary school.
