In summary

Thames High School's Board of Trustees completed a comprehensive attestation to the Ministry of Education confirming compliance with regulatory and legislative requirements across Board Administration, Curriculum, Health and Safety, Personnel, Finance, and Assets. The October 2023 ERO review identified two compliance gaps: police vetting had not been renewed every three years for at least one person, and the process for filling a casual board vacancy was not sufficiently undertaken. The Board demonstrated strength in its comprehensive approach to regulatory compliance oversight.
