Coding notes

​A student may make a number of separate course enrolments at a Higher Education 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.

Please refer to the Glossary for further information about terminology used in this document.
