MEA41322 / Structures (Sheet Metal) Certificate IV in Aeroskills (Structures) / Sheet Metal Stream

Delivered Via
RPL and Gap Assessment Pathway Self-Directed for Experienced Engineers

This pathway is designed for experienced, self-motivated aircraft maintenance engineers.

Knowledge is assessed through an individualised combination of Recognition of Prior Learning (RPL) and targeted knowledge gap assessments. Practical competency (performance evidence) is assessed via RPL using acceptable practical evidence.

Equivalence of Standard
The RPL and Gap Training pathway does not reduce the competency standard required for the award of the qualification. All learners, regardless of delivery mode, must meet the full requirements of each unit of competency, including performance evidence, knowledge evidence and assessment conditions.
No unit of competency is granted solely on the basis of employment history or documentation without structured assessment and verification.

Workplace Training Pathway On-The-Job Delivery for Apprentices and Trainees

This pathway is designed for workplace delivery and applies to apprentices and trainees undertaking training while employed in an approved aircraft maintenance environment.
Training is delivered in accordance with a structured training plan and includes face-to-face contact, workplace-based assessment, and defined progression milestones aligned to competency outcomes.

How We Train

How We Undertake Training (RPL & Gap)

Training for students in the RPL and Gap pathway is self-directed online for theory only.

Theory Training

Training for students taking the RPL & Gap training pathway is self-directed online, but supported with engaging learner resources, regular webinars and Q&A sessions, 1:1 tutoring on request, and support from our training team when required.

The following training and resources are provided for each Unit of Competency:

  • Audio lecture (available as a podcast feed)^
  • Sigma Digital Learner Guide / PDF Learning Materials
  • Toolbox 60 webinars (students can attend fortnightly online)
  • Live Q&A sessions (students can attend fortnightly online)
  • Quarterly check-in
  • Tutoring sessions (on request)

Note: Practical training is not offered for this delivery mode. This pathway is designed for engineers with existing experience and supporting aviation industry-standard documentation (e.g. Journal of Industrial Experience, task cards). Students are expected to provide evidence of practical competency, which is assessed via RPL in line with SAC’s Acceptable Practical Evidence Guidelines.

Where practical training is requested, this may be arranged on a fee-for-service basis for groups, either onsite at SAC facilities or offsite at an approved AMO/MRO facility.

^Audiobook rollout in-progress - not all units will include an audiobook at time of enrolment

How We Undertake Training (Workplace Delivery, Including Apprenticeships & Traineeships)

Training for students in the workplace delivery pathway is undertaken in two parts: theory and practical.

Theory Training

Theory training is conducted online and supported by structured learning resources.

For each Unit of Competency, learners:

1. Listen to an audio lecture (podcast format) to gain foundational understanding of the unit
2. Complete recommended readings, including the learner guide / supplementary materials

Fortnightly webinars are delivered covering topics common to Aeroskills outcomes, concluding with a live Q&A tutoring session.

Students are required to attend monthly one-on-one online check-ins with their instructor to discuss progress and address any learning challenges. Additional one-on-one sessions may be booked where required.

The following training and resources are provided for each Unit of Competency:

  • Audio lecture (available as a podcast feed)^
  • Sigma Digital Learner Guide / PDF Learning Materials
  • Toolbox 60 webinars (fortnightly online, mandatory attendance at least every 8 weeks)
  • Live Q&A sessions (fortnightly online)
  • Monthly check-in
  • Tutoring sessions (on request)

Practical Training

Practical training is conducted in the workplace by approved supervisors.

Supervisors are supported with:

  • Instructor guidance
  • Per-unit practical guidelines
  • Competency checklists

Sigma Aerospace College also conducts workplace visits at a minimum of every 26 weeks to:

  • Provide learner and employer support
  • Assess and sign off Aeroskills journals/logbooks
  • Conduct workplace observations where required

^Audiobook rollout in-progress - not all units will include an audiobook at time of enrolment

How We Assess

How We Undertake Assessment (RPL & Gap)

Sigma Aerospace College operates a four-stage RPL & Gap assessment process following successful application and onboarding.

Assessment Phase 1 – Gap Analysis

Once the onboarding process is complete and initial documentation has been provided, SAC undertakes an assessment of prior learning, applicable credit transfer, and any identified knowledge gaps.

At this stage, an invoice is issued for tuition fees (the course fee listed on the website, less any approved credit transfer). Once payment is received:

  • The customised learning environment is unlocked
  • An initial RPL report (as required by CASA) is issued

This invoice covers all tuition fees, training materials, and any applicable CASA exams.

Assessment Phase 2 – Gap Assessment (Theory) and RPL Evidence Collection (Practical)

Once the customised learning environment is unlocked in the learning management system (aXcelerate), students are presented with:

  • Knowledge gap assessments for Units of Competency not granted in full during Phase 1 via RPL or credit transfer
  • Practical evidence upload assessments for outstanding Units of Competency

Submitted practical evidence is assessed via RPL against Unit of Competency performance evidence requirements.

Assessment Phase 3 – Competency Conversation

Following completion of gap assessments and submission of sufficient practical evidence (as defined in the Acceptable Practical Evidence Guide), students undertake a clustered competency conversation with an instructor.

  • Format: one-on-one discussion
  • Duration: approximately 30–60 minutes
  • Purpose: final verification of competency

Assessment Phase 4 – CASA Exams

For training products with a CASA outcome, the final stage involves preparation for and completion of invigilated CASA examinations. An administrator will contact the student at the conclusion of Phase 3 to arrange suitable exam times.

Note: Students may apply for recognition of prior learning for any existing practical experience at any time, as long as at the time of Sigma's assessment of that evidence as prior learning (i.e. when uploaded to the relevant capture in the LMS) the evidence meets the terms in the acceptable practical evidence guide, is authentic, sufficient, and meets unit requirements.

How We Undertake Assessment (Workplace Delivery, Including Apprenticeships & Traineeships)

Sigma Aerospace College undertakes assessment across theory and practical components. Students are deemed competent only when evidence demonstrates 100% coverage of each Unit of Competency.

Theory Assessment

Theory is assessed using the following methods:

  • Knowledge assessments (multiple choice, short answer, matching exercises)
  • Competency conversations

Practical Assessment

Practical assessment is conducted using the following methods:

  • Supervisor observation checklist (covering all unit criteria), signed off by Sigma Trainer & Assessor
  • Task evidence established via records in the student’s work history sheets (as contained in their Journal) or, where appropriate, equivalent Industry Evidence
  • Workplace observation (where appropriate)

Note: Students may apply for recognition of prior learning for any existing practical experience at any time, as long as at the time of Sigma's assessment of that evidence as prior learning (i.e. when uploaded to the relevant capture in the LMS) the evidence meets the terms in the acceptable practical evidence guide, is authentic, sufficient, and meets unit requirements.

  • Minimum age 18 years at commencement of course

Education
