RPL for Certificate III in Engineering - Mechanical Trade

MEM30219 · 96 points · what to gather before you start.

Updated 2026-09-22

Certificate III in Engineering - Mechanical Trade is awarded on 96 points, not on a count of units — every unit you claim is worth a stated number of them. Through Recognition of Prior Learning, each unit is assessed on evidence of work you have already done rather than on training you sit through.

What the assessment looks at

Every unit sets out what you must be able to do and what you must know. An assessor works through them one at a time, asking the same question each time: does this person's evidence show they can do this reliably, in a real workplace, recently enough to count?

You can read the full requirements for MEM30219 on the national training register. They are public, and worth a look before you spend anything — if the units describe work you have never done, RPL is not your route.

Evidence worth gathering before you start

  • Photos of completed jobs, ideally showing a few stages of the same job, with their original dates intact.
  • Job sheets, dockets, work orders or site diaries covering a spread of jobs.
  • Supervisors, employers or clients who will confirm specifically what you did.
  • Any licences or tickets you already hold.

How the guided process works

You work through the units one at a time, talking about jobs you have actually done, until what you have claimed is worth 96 points. You can speak rather than type. Add photos as you find them, and stop whenever you like — progress saves itself, and most people spread this over weeks while they dig out records. At the end you have an evidence portfolio your RTO's assessor can work through.

What this does not do

It does not assess you, and it cannot promise you MEM30219. An assessor at a registered training organisation makes that decision and may require further evidence or training. What a complete portfolio buys you is a fair assessment rather than a rejection over paperwork.

The 96 points you need, and the 86 units you can earn them from

Certificate III in Engineering - Mechanical Trade is awarded on points, not on a count of units. The 12 core units are compulsory and are worth 33 points between them; the remaining 63 come from the 74 electives below, and they are not worth the same as each other — how many units you end up doing depends entirely on which you pick. Read both lists before you spend anything — it is the fastest way to tell whether RPL is your route. If most of this describes work you have done, you have a case to make. If whole sections describe work you have never touched, an assessor will say so, and doing the course is the honest answer.

Worth knowing: 80 of them have a prerequisite unit, so the order you gather evidence in matters.
