  • 5.1Clear work area and dispose of, re-use or recycle materials in accordance with regulatory and workplace requirements.
  • 5.2Clean, check, maintain and store tools and equipment in accordance with manufacturer and workplace requirements.

Performance evidence

  • To demonstrate competency, a candidate must meet the elements and performance criteria of this unit by patching components within a precast element, including: a Stitch Plate recess (200mm x 200mm x 35mm deep min.) and any two of the following: a lifting insert void former (5 tonne lifting insert recess min.), a cast-in-insert recess (M20 ferrule nailing plate recess), a grouting duct (50mm diameter grout duct recess).

Questions about assessing CPCPRE3001

What does an assessment tool for CPCPRE3001 need to cover?

To satisfy the Principles of Assessment and Rules of Evidence, an assessment for CPCPRE3001 needs to address all 94 unit components: 5 elements with 23 performance criteria, 1 performance evidence requirements, 70 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.

How does Auditori generate an assessment tool for CPCPRE3001?

Auditori pulls the current release of CPCPRE3001 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.

Is the first assessment tool really free?

Yes. Every new account includes one free credit — enough to generate the complete assessment tool for CPCPRE3001 — with no card and no subscription required. After that it's pay-as-you-go per unit.

Can I check my existing CPCPRE3001 assessment instead of generating a new one?

Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of CPCPRE3001, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
