NSM Insurance has a program for Schools, which includes Teacher Liability (Educator's Legal Liability). If we have the opportunity to quote on the School, we might be able to indirectly tackle your need/inquiry. If you only seek mono-line teacher liability, I'd suggest looking at the Hiscox online portal (
www.hiscox.com) - depends on exact operations (Education Consultant for example).
