The latest ERO report for Makoura College marks a brilliant turnaround since the school almost closed in 2008, says principal Tom Hullena.
The review was completed in December and is the first conducted under the governance of a board of trustees that was established after Tim White stood down as commissioner at the school in 2011.
The school had been forced to the brink of closure three years earlier after dwindling college funds and a declining roll of barely more than 200 pupils stymied its last board of trustees, who resigned en masse.
A groundswell of community support and opposition to closure had led to the appointment of Mr White as commissioner and Mr Hullena as principal.
Successive reports since the near closure had shown a gradual building of capacity, according to the latest review, to improve and sustain the quality of education at the school.
