A USI is an account or reference number made up of numbers and letters. The USI will allow an individual to access training records, entered in the national vocational education and training (VET) data collection, to be linked.
The USI will make it easier for students to find, collate and authenticate their VET achievements into a single transcript. It will also ensure that students’ VET records are not lost.
The USI initiative will:
Seamlessly link information about a student’s VET achievements, regardless of where they studied
Enable students to easily access secure digital transcripts of their achievements
Give students access to, and more control over, their educational information
