Updated 12.20pm: Destiny Church is considering taking the Ministry of Education to court after its third attempt to have its school become part of the state system was rejected.

Destiny School spokeswoman Anne Williamson says they're considering their options - and one may be a legal challenge.

"Somebody has come forward and offered to pay our legal fees, someone who has looked at the history of how it's gone for us and is as concerned as we are."

The PPTA opposed the move, but president Angela Roberts says that's not to do with the people trying to open it.

She says if Destiny was allowed to open a public school for a small roll, it would suck resources and funding from others in the area.

"What they should be doing with their significant resources is thinking about how they can better support the kids in their community, already in the local schools. They should be backing those horses to win."

PPTA president Angela Roberts says instead of trying to set up its own school, Destiny should be supporting its community.

"People have got grand ideas about doing a better job than their local school, so they apply for special character, or they apply to be a charter school where the bar is even lower."
