The Individual Knowledge Assessment of Number (IKAN) can be used to determine a student's stages on the knowledge domains. There are four versions of the IKAN, and each is available in two formats. The Flash versions allow you to choose to start the assessment at a particular part. The mp4 versions are video files which you can download and use offline. Both versions now include audio. For the Flash versions you will need to unmute the audio before starting the assessment.
In response to user feedback, and in consultation with the Ministry of Education, the timings have been extended for some questions in the IKAN assessments to allow sufficient time for students to record their answers (18/9/12).
Older versions of IKAN are also still available.
