Browse coursesGet Course maps UEE51225 to its occupations using the register’s own outcome wording, shown with ANZSCO codes (here, 3421) so the mapping can be checked. Job advertisement counts come from the Jobs and Skills Australia Internet Vacancy Index and count online ads, not vacancies filled. Enrolment counts come from NCVER Total VET Activity and count people in training, not completions. Outcome benchmarks marked “typical” are medians computed by Get Course across all qualifications at the same level in the same NCVER collection; they are derived figures, not official NCVER benchmarks. Funding rows appear only after verification against the official state program list.
