Rule 6432 – Class Size

The guidelines below will be used in maintaining class size.

Reasonable effort will be made to maintain class sizes of:

  • Grades K-1: maximum of 22
  • Grades 2-3: maximum of 24
  • Grades 4-5: maximum of 26
  • Middle school academic subjects: maximum of 30
  • High school academic subjects: maximum of 30
  • Secondary level physical education: maximum of 40
  • Secondary level band, choir, orchestra and theater may exceed a class size of 30+

Reasonable effort will also be made to avoid elementary split classes entirely. If splits are needed, reasonable effort will be made to not exceed more than twenty-two (22) students in a class.

Classes may combine at times for educational purposes, thereby exceeding the numbers outlined above.

Reasonable effort will be made to follow staffing guidelines for special education that are determined through the use of the Statewide Caseload Formula. Classroom models are administratively determined based upon the needs of students and the percentage of time students receive special education services.
