Regulation 464/97 provides only limited direction about the appointment of additional voting members, sometimes called members at large. In Regulation 464/97, Section 2 (5) the board may appoint one or more additional members who are not:
- Representatives of a local association
- Trustee members of the board
- Members of another committee of the board
PAAC on SEAC recommends that all school boards and school authorities develop policies for SEAC that clearly define the number of additional members and the criteria that will be used to select additional members.
