2 · What it shows

  1. 1

    A separate group may not exceed 8 students to one educator, or 12 with an aide.

  2. 2

    The more separate the group, the lower the cap: 16 partly separate, 12 fully.

  3. 3

    The rule caps children, not adults: it sets 0 limits on adults, and a plan can add aides.

  4. 4

    41 of 258 children were counted substantially separate in FY2026; that is not a count of groups.

Parsed from the sentences that state them. Every tier names one educator; an aide is what raises the ceiling.

What was said

  • “Julianna Hanscom states there is no formula. The school is aware of what students are in programs who will then go into a program next year. There hasn’t been a large or small caseload, and the inclusion of teachers is between 15 to 20 students”

    Finance Committee minutes, 2024-03-14

  • “seven of her IEP students with significant pull-out service needs were being seen by a paraprofessional rather than a certified special education teacher”
