A Northland school is refusing to obey an order by Education Minister Hekia Parata to close its unit for senior students.
Moerewa School claims the NCEA results for their Year 11 to 13 students are better than those at nearby colleges.
The school tried to formalise its senior class last year - up until now it has been run as a satellite unit of an Auckland school.
But the then-minister Anne Tolley ordered it to close, noting that the school had refused to implement national standards.
The Qualifications Authority has told the school it has audited 84% of the results and has concerns about the validity of 29%.
Principal Keri Milne-Ihimaera disputes the results and says the ministry should visit the school before making any decision.
She says the ministry should also consider the school's lack of truancy and the support it enjoys from the community.
Ms Milne-Ihimaera says she will deal with any response from the ministry when students return to the school after holidays on 23 April.
