Commentary:
The performance of some MI (Mäori Immersion) students was affected by their limited Mäori language skills. Also, the phrase "kei reira töna oranga" was ambiguous. Because of the latter fault, a statistical comparison of GEd (General Education) and MI (Mäori Immersion) student performances was not appropriate.
