The president of the Te Tai Tokerau Principals Association is challenging the Government to release a report on the controversial Whangaruru charter school.
Of the five charter schools that opened this year, reports for four of the schools from the Education Review Office were released in the past month.
However, the report for Te Kura Hourua ki Whangaruru has been withheld after an assurance to the Northern Advocate two months ago it was being prepared for "imminent public release".
In the first term the kura faced many issues, including student drug abuse on campus, students using gang signs, bullying, declining enrolment and the resignation of a co-director.
The school, located on a farm 65km northwest of Whangarei, also faced criticism from the ERO after a visit in April, which found fault with many areas, including curriculum and school morale.
