Australia issues the same unrestricted electrical licence for graduates of two structurally distinct qualifications. This analysis maps where they align — and where they don’t.
Every MEM31219 unit was scored against every UEE30820 unit using a five-layer semantic similarity model — 3,737 comparisons in total. Each point below represents one MEM31219 unit plotted at its best-possible match score against the national standard.
Most units cluster at high semantic similarity but moderate structural alignment — the qualifications cover the same electrical domains but were written through entirely different competency frameworks. Same territory; different maps. Only two units break through the 70% threshold into substantial similarity.
The scoring model separates what a unit teaches from how it structures assessment. Embedding similarity captures meaning — averaging 87% across all MEM31219 units. But performance criteria alignment, which measures whether the two qualifications break that knowledge into the same assessable steps, averages just 6%. The gap reveals the core structural divide.
MEM31219 and UEE30820 teach recognisably similar electrical content — the embedding model confirms this. But they decompose that content into competency units through entirely different structural conventions. MEM uses manufacturing-oriented language (“fault-find,” “rectify,” “work safely in manufacturing”). UEE uses electrotechnology-specific language (“verify compliance,” “AS/NZS standards,” “low voltage circuits”). The licensing framework treats both vocabularies as equivalent for the purposes of issuing an unrestricted electrical licence.
MEM31219 achieves a 61% average alignment with the national standard. The remaining 39% represents competencies with no meaningful UEE equivalent. The licensing framework accepts this gap and issues an unrestricted licence to work live, unsupervised, on high-voltage systems.
A Cert II in Electrotechnology (UEE22025) scores 79% alignment with the national Cert III standard — 18 percentage points higher than MEM31219. The licensing framework grants an unrestricted electrical licence to the lower-aligned qualification and no pathway to the higher-aligned one. The data does not say this is wrong. It asks: if alignment is not the criterion, what is?
Using the same composite scoring methodology, every Cert III qualification in the national training system that shares units with either MEM31219 or UEE30820 was scored against all 101 UEE30820 units. The result: MEM31219’s 61% is the median, not the ceiling.
If 61% alignment grants an unrestricted electrical licence, 19 other qualifications already meet or exceed that bar. This is not a question about one anomalous qualification. It is a question about the evidence base underpinning an entire licensing category across the national training system.
3,737 unit pairs — every MEM31219 unit (37) scored against every UEE30820 unit (101). Each pair received a composite similarity score; each MEM unit retained only its best UEE match.
Five signals, weighted by information value:
65% semantic embedding (Gemini language model, 3072-dim) · 15% performance criteria TF-IDF · 10% element alignment · 7% application text · 3% knowledge & evidence
Substantially similar > 70% composite score. Partial overlap 50–70%. Below 50% treated as distinct. Thresholds set before scoring began.
87 Cert III qualifications scored using the identical method (~700K unit pairs). Per-qualification alignment = mean of each unit’s best UEE30820 match. MEM31219 re-computed at 0.61 as validation control.
Six cross-package units (UEENEEE/UEENEEG series) relied on embedding similarity only due to legacy format constraints. UEE22025 scored against UEE30820 using the same composite method. All source data drawn from training.gov.au national training packages.
