The School Committee's Class Size Policy is available here. Note that this policy was put in place following work done in 1999 by the Class Size Task Force, of which I was a member.

The prior policy set a three types of levels: number of students by grade at a "Target Upper Limit," a "Automatic Review Limit," and a "Add Teacher Limit."

Target Upper Limit (old policy)
- Kindergarten: 20, Grade 1: 20, Grade 2: 23, Grade 3: 25, Grade 4: 25, Grade 5: 25

Automatic Review Limit (old policy)
- Kindergarten: 23, Grade 1: 23, Grade 2: 25, Grade 3: 26, Grade 4: 26, Grade 5: 26

Add Teacher Limit (old policy)
- Kindergarten: 25, Grade 1: 25, Grade 2: 27, Grade 3: 28, Grade 4: 28, Grade 5: 29

The new policy set a single level, "Add Teacher/Aide," while providing language making it clear that the School Committee was not bound to such an addition.

Add Teacher/Aide Guideline (new policy)
- Kindergarten: 20, Grade 1: 20, Grade 2: 23, Grade 3: 23, Grade 4: 25, Grade 5: 25
