- Class size is calculated by dividing the number of students in a program and grade by the number of official classes in that program and grade.
- For schools where core course data is available for grades 5-9, class size is calculated by dividing the number of students in a course by the number of sections in that course, regardless of the grade level of the students enrolled.
- ICT sections that are coded as two separate sections for their General Ed and ICT student cohort will be matched together based on day, period, room, and Core course code.
- All official classes
- Grade 9 official classes are included in schools where it is the terminating grade (i.e. 6-9 schools)
- All courses identified by Core Subject from Table A as English, Math, Social Studies and Science for grades 5-9, where available in STARS. *

In the report, duplicated sections are subtracted as "MATCHED SECTIONS" and paired sections are added back as "ASSUMED TEAM TEACHING".*
- Self-contained Special Education (Spec Ed)
• Class size is calculated by dividing the number of students in a course by the number of official classes in that course, regardless of the grade level of the students enrolled.
- Courses where the core class flag is equal to “Y” in the following subjects:
- English classes (courses beginning with “E”)
- Science classes (beginning with “S”)
- Math classes (courses beginning with “M”)
- Social Studies classes (courses beginning with “H”)
- General education classes with more than 100 students
