Company Membership

As a large and complex independent school operated by a not-for-profit public company, good governance is vitally important at Chairo. Christian parents and guardians who are committed to Chairo, and to Christ-centred education, are encouraged to apply to become members of the company. Company members are expected to take an active interest in the affairs of the company and attend one or two general meetings each year (whether in person or online), where they are able to vote in relation to key decisions about future direction and development.

Governance at Chairo Booklet

The Board of Directors

The majority of our Directors are parents or guardians of children currently attending the school, because we believe that parents need to be actively involved in the education of their children. The most critical task for the Directors is to determine the vision and mission for the school. This provides a picture of the future and guides our strategic planning, measures existing programs, determines the basis for the appointment of staff, and generally shapes all that happens at Chairo.

Our Directors are very aware of the need to separate the strategic and goal-setting functions of leadership from the day-to-day operational aspects of the school. The Board therefore establishes policies that govern the operations of the school, which are then implemented by the Executive Principal, Business Manager and other members of Chairo’s executive leadership team.

Directors are well-informed about all areas of Chairo’s operations via information provided regularly by executive staff, other members of the Chairo community, and various committees. They take their responsibility very seriously to govern wisely and to make prayerful and informed decisions from a biblical and Christian worldview perspective.

Strategic Statement

Our Strategic Statement (Growing Stronger), for the ten years from 2023 to 2032, elaborates on the foundations that Chairo has been built upon and is the starting point for the creation of a strategic plan of future goals. In turn, the strategic plan enables the development of operational plans that ‘flesh out’ how the strategic plan will be implemented over the next time period, with key milestones along the way.
