Could RPL Be Right for You?

Experience can be evidence.

RPL is the process that helps you demonstrate it.

Recognition of Prior Learning (RPL) is a formal assessment process that evaluates the skills, knowledge, and experience you've gained through your career to determine whether you meet the requirements of a nationally recognised qualification. It isn't a shortcut — it applies the same assessment standards as any other pathway.

RPL typically involves:

📋

A review of your work experience against the qualification requirements

💼

Compilation of an evidence portfolio demonstrating your competency

👤

Assessment by a qualified assessor from a Registered Training Organisation

🎯

If gaps are identified, targeted training to build on your existing expertise

ℹ️ Important Pathway Advice

RPL isn't the right pathway for everyone. If you don't have substantial, relevant, and current industry experience, a traditional study pathway may serve you better.

Our approach:

“We'd rather guide you to the right pathway than enrol you in the wrong one.”

What Kind of Experience Counts?

If RPL becomes available for this qualification, the types of experience and evidence that would typically be relevant include:

🛠️

Work History & Roles

  • A comprehensive resume or CV detailing your engineering trade experience
  • Position descriptions from current or previous employers in the plant mechanic sector
  • Letters of service or employment references confirming your technical roles
📊

Technical Documentation

  • Service reports and maintenance logs for mobile or stationary plant
  • Diagnostic checklists for hydraulic, electronic, or diesel engine systems
  • Completed job cards or work orders detailing specific repairs and fault-finding
🛡️

Safety & Compliance

  • JSA/SWMS records for heavy plant repairs and high-risk maintenance tasks
  • Site induction records and hot work permits for engineering environments
  • Records of safe manual handling and workshop safety participation
📷

Photos & Videos

  • Images of engine rebuilds or component replacements in progress
  • Videos demonstrating fault-finding or diagnostics on mobile plant equipment
  • Photos of correctly assembled engineering components and work areas
📝

Technical Planning

  • Interpreted technical drawings or schematics used for repairs
  • Work plans for complex assembly or commissioning tasks
  • Records of engineering measurements and computations performed on the job

Frequently Asked Questions

Everything you need to know about this qualification and RPL.

How do I get started with RPL for this qualification?
The process begins with a free skills review where we assess your plant mechanic experience. From there, you will compile a portfolio of evidence, such as work logs and photos, which our RTO partner will assess to grant your qualification.
Is an RPL qualification the same as one from full-time study?
Yes, a qualification obtained through RPL is identical to one earned through traditional study. It is nationally recognised and meets the same Australian Qualifications Framework (AQF) standards.
How long does the process typically take?
Most candidates complete their RPL process within 4 to 6 weeks once their evidence portfolio has been submitted to our RTO partner for assessment.
What kind of evidence will I need to provide?
You will need to provide evidence of your work on fixed and mobile plant, which may include site records, job cards, photos of your work, supervisor testimonials, and videos of you performing specific mechanical tasks.
Does this qualification cover diesel fitting and engine repairs?
Yes, the MEM31419 qualification specifically addresses the skills required for diesel fitting and the maintenance of combustion engines in both stationary and mobile plant equipment.
Can I use this qualification for trade recognition in the mining industry?
Absolutely. This Certificate III is the standard trade qualification required for plant mechanics and diesel fitters working across the mining, construction, and manufacturing sectors.
Is an RPL qualification the same as one obtained through full-time study?
Yes. RPL is a legitimate form of assessment within the Australian VET system. The qualification issued is identical to one obtained through any other mode of delivery and is nationally recognised under the Australian Qualifications Framework.
Who assesses my evidence?
Your evidence is assessed by a qualified assessor employed or contracted by the delivering Registered Training Organisation (RTO) — not by RPL It. The assessor holds the credentials required under the 2025 Standards for RTOs and has current industry experience.
What if gaps are identified in my skills?
If the assessor identifies areas where your evidence does not fully demonstrate competency, the RTO can provide gap training. The RTO will discuss any associated requirements or costs with you if this becomes necessary. Gap training is targeted to the specific areas identified and is designed to help you meet the full requirements of the qualification.
What if I don’t have enough experience for RPL?
If the initial skills review indicates that RPL is not suitable for you at this time, we’ll let you know honestly and discuss alternative options. We would rather direct you to the right pathway than enrol you in a process that won’t lead to a successful outcome.
How long does the RPL process take?
Based on our experience, the majority of RPL candidates receive their qualification within 4–6 weeks of their complete evidence portfolio being submitted to the RTO. However, this is an average based on past outcomes — not a guarantee. Factors include qualification complexity, evidence completeness, whether gap training is required, and the RTO’s current assessment capacity.
Can I do this from outside Australia?
This depends on the specific qualification. Many qualifications are based on Australian codes, standards, and legislation, and some require access to an Australian workplace for assessment. If you are based outside Australia, please contact us to discuss whether RPL is feasible for your circumstances.
