An independent school board’s entire duty to a school is to employ a Head of school, be the fiduciary for the school, and uphold the mission. The head of school’s sole duty is to uphold the school’s mission. These are basic governance and accreditation standards.
I think this statement makes a bit more sense if they’re talking about what the Board itself will or won’t say. But I can see the extreme case right now of either a school community pressuring the school to speak out on things and/or a Head wanting to speak out, and the Board using this statement to not-so-gently remind everyone of how independent schools are supposed to work.
As a former trustee, it would be a pretty crazy situation that would put us in the position of having to say something like this. I don’t envy the work they had to do to get to this statement, but if I were a current trustee I would copy and paste this into a just in case file for myself for the future.
