There is however evidence that the revitalisation efforts are taking hold, as can be seen in the teaching of "te reo" in the school curriculum, the use of Māori as an instructional language, and the supportive ideologies surrounding these efforts. In 2014, a survey of students ranging in age from 18 to 24 was conducted; the students were of mixed ethnic backgrounds, ranging from Pākehā to Māori who lived in New Zealand. This survey showed a 62% response saying that "te reo Māori" was at risk. Albury argues that these results come from the language either not being used enough in common discourse, or from the fact that the number of speakers was inadequate for future language development.
