The following standards for class size have been established by the Department of Elementary and Secondary Education (DESE). These standards will be adhered to in respect to grade level and course subject with the exception of only the most unusual circumstances. The Assistant Superintendent of Human Resources has the authority to make adjustments in class size at the beginning of each semester.

The District's goal is to maintain classes in accordance with Missouri School Improvement Program (MSIP) standards as follows:

Primary Grades, K–2

17–25 students


*          May be lowered to 15 if the class make up consists of exceptional children. One teacher assistant will be hired per grade level for class sizes exceeding 25.5 for K–2.

Intermediate Grades, 3–4

20–27 students


*          One teacher assistant will be hired per grade level for class sizes exceeding 27.5 for 3–4 grade level.

Intermediate Grades, 5–6

22–30 students


*          One teacher assistant will be hired per grade level for class sizes exceeding 30.5 for 5–6 grade level.

Secondary Grades, 7–12

25–33 students

(Students in self-contained special education classes shall count toward the MSIP class size standards if they are mainstreamed into a regular classroom for three or more hours a day.)

Class size shall not exceed 33 students per core-content area class and every effort will be made to see that a teacher's overall class load will not exceed 150 students (excluding non-instructional and/or advisory type classes). The district will monitor class loads on a periodic basis to ensure compliance with class size standards. If a teacher's class load exceeds 150 students, he/she should address the concern with his/her immediate supervisor at the building level. If a satisfactory resolution is not reached at the building level, the teacher may contact the Assistant Superintendent for Human Resources to discuss the matter.

Class Size by Type of Course Offering

High school beginning and advanced classes in the same subject may be combined (example: Spanish I and Spanish II). Total enrollment in such classes shall not exceed 20 students.

The district goal for enrollment in special courses offered to meet student's graduation requirement needs is 33.

For classes not specifically listed in this policy, the standards established by the Missouri School Improvement Plan (MSIP) will serve as the district's class size standard. If MSIP does not have an applicable standard, the Assistant Superintendent for Human Resources will determine a reasonable standard.
