What ERO found
The Education Review Office’s latest report on the school is a Te Ara Huarau School Profile Report from May 2024. This kind of report sets out what ERO and the school will evaluate together, here how well staff build assessment practices that lift achievement and make outcomes fairer for all students, working with the local Kāhui Ako and university-led professional learning.
ERO pointed to teachers who see inclusion and caring relationships as key to better outcomes, staff and whānau who give their own time and resources to widen opportunities for students, leadership that is being strengthened, and a supportive wider community.
Next, the school plans to gather more reliable assessment information to plan and teach more responsively, agree shared systems for closely tracking each student’s progress, report regularly to the board on progress, keep parents and whānau better informed, and continue professional learning on assessment.

Enrolling
Students who live in the home zone have the right to enrol. Out-of-zone places are offered under the school’s enrolment scheme, by ballot when there are more applicants than places.
The scheme says the board announces the number of out-of-zone places, how to apply and the ballot date by public notice each year, and the school’s website links to an online enrolment form.
