Coding notes

A student may make a number of separate course enrolments at a Higher Education/VET Provider (Provider) in the one year or over a number of years, and the CHESSN must be constant across courses and over time.

Where a student returns to a Provider to resume a course or to undertake a new course, the CHESSN must be the same as that used at the time of the student's first enrolment at a Provider after 31 December 2004.

The CHESSN will only be used to allow eligibility to Commonwealth support to be facilitated and monitored.
