Constructive Communication Policy

We are committed to fostering a respectful school culture that enables honest and reflective dialogue. We collectively take responsibility for nurturing a positive learning environment that supports the development of every child’s Head, Hands, and Heart.

Constructive school communication is essential for a healthy school environment. It nurtures empathetic and positive assumptions about all stakeholders in a shared effort toward student success. This policy clarifies what constructive communication looks like at RIS. It also offers parents and faculty guidelines for which communication channels are appropriate and most helpful when looking for information, to attain clarity on a matter, or to address differences of opinion.
