CLASS SIZE
Tennessee state law, §49-1-104, outlines the class size maximums for in-person classes as follows:
Grade Level Average Max Class Size
K-3 20 25
4-6 25 30
7-12 30 35
Career and Technical Education 20 25
Class average and max class size limits do not apply to related arts classes, ex: P.E., ROTC, technology, music, art, etc. However, the instructional program cannot be negatively impacted by the number of students assigned to the course.
The limits also do not apply to classes that have extra students due to lack of substitutes since that is temporary.
Class sizes are established in state law but are governed by State Board of Education Policy 0520-01-02.31(4). You can find the full policy here.
