Assessment for qualifications

At the time of publication, achievement standards were in development to align them withThe New Zealand Curriculum. Please ensure that you are using the correct version of the standards by going to the NZQA website.

The NZQA subject-specific resources pages are very helpful. From there, you can find all the achievement standards and links to assessment resources, both internal and external.

Aligned level 1 achievement standards were registered for use in 2011 and level 2 for use in 2012; level 3 for use in 2013.
