Class Size

The South Portland Board of Education recognizes that there is a relationship between class size  and student achievement and that this relationship varies greatly across grade levels, among  subjects and by methods of instruction. Therefore, the recommended class size in the elementary  and secondary schools shall be determined by several variables including grade level, subject  area, nature of the students in the classroom, nature of the learning objectives, availability of  classroom space, instructional methods and procedures used, and budgetary constraints.  

Keeping all of these variables in mind, the following class size ranges shall serve as a general guideline for the organization of classes in the elementary and secondary schools:  

  1. Class Guideline 

    •  Kindergarten through grade 2: 15-20 students  

    •  Grades 3-5: 15-24 students  

    •  Grades 6-8: 15-25 students  

    •  Grades 9-12: 15-26 students  

  1. Special class size circumstances, including, but not limited to:  

    • Classrooms falling under OSHA guidelines, such as Applied Arts;  

    • Number of available lab stations;  

    • Instrumental and choral music classes;  

    • Exceptionality courses.  

  1. When any elementary or secondary school class fails to meet or exceeds the recommended class size range, the Building Administrator shall notify the Superintendent of Schools. The  Superintendent, in consultation with the Building Administrator, shall consider options to resolve  the issue. Options may include, but are not limited to:  

    • Maintaining class size  

    • Assigning additional staff  

    • Transferring some or all students to a different class or school, or  

    • Canceling the course  

    • The Superintendent's decision will be communicated to the Board of Education with the  understanding that Board approval will be required to hire any additional staff.
