Howe Green House School Governors come from all walks of life and many have a personal link with the school.  Current and past parents, Howe Green House alumni and members of the wider community work together tirelessly for the benefit of the school.

Their role as ‘critical friends’ of the school’s leadership team is undertaken with commitment and enthusiasm and they each bring their own experience and expertise to help the school flourish and forge ahead.

The duties of the Governors are varied.  From the responsibility of ensuring the school operates within the regulatory requirements to presiding over educational changes and development of the school site, their role is to uphold the best interests of the school and its community and ensure its future success.
