In-House Lean Six Sigma Training? Here’s How to Turn It Into a Certification You Can Take With You

Last updated: August 2026

TL;DR: If you attended Six Sigma or Lean Six Sigma training that your employer ran in-house, what you learned is real — but the certificate probably isn’t portable. Most internal programs issue a completion record your current employer recognises, not an externally verifiable credential a future employer, recruiter, or tender assessor can check. The fastest way to fix that without repeating everything you already know is Recognition of Prior Learning (RPL) — a fast-tracked pathway that credits your existing skills and experience toward a full external certification. At Lean Six Sigma Australia, RPL is available at Green Belt ($1,695) and Black Belt ($2,650), and if you’re covering the cost yourself rather than through an employer, Afterpay is available at checkout on eligible courses so you can spread the cost over four instalments instead of paying it all upfront.

The problem with training only your employer recognises

A lot of workplaces run their own internal Six Sigma or process-improvement training — sometimes delivered by a consultant, sometimes by a senior staff member who was certified years ago and now trains others informally. It’s genuinely useful: you learn DMAIC, you work on real projects, you build skills that matter.

The catch shows up later, usually at exactly the wrong moment — when you’re applying for a new role, updating your LinkedIn profile, or a client or tender process asks for evidence of your certification level. An internal program typically can’t offer any of the following, because it was never built to:

• A credential a future employer can verify independently. Most in-house training issues a certificate of completion or an internal sign-off, not a record that exists outside your current employer’s own files.
• A recognised belt level. “Completed our internal process improvement training” doesn’t map cleanly to Yellow, Green, or Black Belt — the language the rest of the industry actually uses and screens for.
• Portability. If you change employers, the credential usually doesn’t travel with you in any checkable form.

None of this means the training was wasted. It means the skills are real but the paperwork isn’t doing its job yet — and that’s a fixable, not a start-again, problem.

You don’t have to start from scratch: Recognition of Prior Learning

This is exactly what Recognition of Prior Learning (RPL) exists for. Instead of repeating content you already know from your internal training and on-the-job experience, RPL assesses what you can already demonstrate and fast-tracks you toward an externally issued certification at the appropriate belt level.

At Lean Six Sigma Australia, RPL is currently available at two levels:

• Green Belt – Recognised Prior Learning — $1,695 AUD
• Black Belt – Recognised Prior Learning — $2,650 AUD

Eligibility isn’t a fixed checklist published on the website — it’s assessed case by case, based on what you can actually demonstrate. The practical first step is straightforward: contact Lean Six Sigma Australia with a short summary of your internal training and the process-improvement work you’ve actually done, and they’ll tell you whether you qualify for the RPL pathway and which belt level it fast-tracks you to. If your background doesn’t fit RPL, the standard course pathway is always there as a fallback — you’re not locked out either way.

What “externally recognised” actually means

Worth being precise here, because “recognised” gets used loosely across the whole Six Sigma industry — including by us, if we weren’t careful about it.

An externally issued Lean Six Sigma Australia certificate means your credential comes from an organisation outside your employer, at a named belt level the wider industry understands, and one that can be verified independently on request — not just taken on your word or your manager’s sign-off. That’s a genuinely different thing from your current in-house program, and it’s the gap this whole pathway closes.

For most people moving from an internal program, the practical bar you’re trying to clear isn’t formal accreditation — it’s having a certificate a future employer, recruiter, or client can actually check and trust. RPL gets you there.

Paying for it yourself — instalments with Afterpay

If your employer funded your original in-house training, it’s easy to assume they’ll fund this too — but plenty of people reading this are planning to pay for their own external certification, either because they’ve since changed jobs, their current employer’s training budget doesn’t stretch to it, or they’d simply rather own the credential outright.

If that’s you, you don’t have to pay the full course fee in one hit. Afterpay is available at checkout on eligible courses, letting you split the cost into four interest-free instalments. For example:

• Green Belt (standard course), $1,495 — 4 interest-free payments of $373.75 with Afterpay
• Green Belt (RPL pathway), $1,695 — 4 interest-free payments of $423.75 with Afterpay

Afterpay availability is confirmed at checkout on a course-by-course basis, so check the specific product page for your belt level and pathway before you enrol — if it’s not showing as an option there, get in touch and we can confirm what’s available.

If your employer is willing to cover it instead

Self-funding isn’t the only option, and it’s worth asking before you rule it out. Many students do have this course covered by their employer’s professional development or training budget — even when the original in-house training wasn’t run by an external provider. Most course pages let you flag “my employer” as the one covering the cost when requesting a quote or invoice — worth raising directly with your manager if a professional development budget is available.

What our students say

Skills, portability, and course quality are three different questions, and it’s worth being just as straightforward about the third as the first two. You can read full graduate testimonials — including from students who completed both Green Belt and Black Belt — on our Student Reviews page.

How to get started

1. Work out where your internal training likely sits — roughly Yellow, Green, or Black Belt level, based on the tools and project work you’ve actually done.
2. Contact Lean Six Sigma Australia with a short summary of that training and experience, and ask whether you qualify for RPL.
3. Choose your pathway — RPL fast-track if you qualify, or the standard course if you’d rather build from the fundamentals.
4. Decide how you’re paying — upfront, in four instalments with Afterpay, or via your employer’s training budget if they’re willing to cover it.
5. Complete the course and receive a certificate you can verify and carry with you, independent of any one employer.

If you’re still weighing up which belt level is the right fit regardless of your training history, our guides to Six Sigma certification and Lean Six Sigma certification break down what each level actually qualifies you to do, or you can browse the full certification range directly.

FAQ

Will my employer’s in-house Lean Six Sigma training be recognised by other employers?

Not automatically. Internal training programs are genuinely valuable for building skills, but they typically issue an internal completion record rather than an externally verifiable credential, so a future employer usually can’t check it independently. Recognition of Prior Learning (RPL) is the usual route to convert that experience into an externally issued, portable certification.

What is Recognition of Prior Learning (RPL) for Six Sigma?

RPL is a fast-tracked certification pathway that credits skills and experience you already have — including from internal or employer-run training — toward an externally issued belt certification, rather than requiring you to repeat content you already know.

Do I need to redo the whole course if I already have on-the-job Six Sigma experience?

Not necessarily. If you qualify for RPL, your existing training and project experience is credited toward the certification, so you’re not starting from zero. Eligibility is assessed case by case — contact the provider with a summary of your background to find out.

Can I pay for my Six Sigma certification in instalments?

Yes, on eligible courses. Afterpay is available at checkout on select Lean Six Sigma Australia courses, splitting the cost into four interest-free instalments — for example, four payments of $373.75 on the standard Green Belt course. Check the specific course page to confirm Afterpay is available for your chosen belt level and pathway.

Is Lean Six Sigma Australia’s certification externally accredited?

Lean Six Sigma Australia’s certification is externally issued and independently verifiable, which solves the portability problem of an in-house-only credential. It is not, however, independently accredited under ISO/IEC 17024 — a position shared by the large majority of Six Sigma providers globally. The one current exception in the industry is ASQ’s Certified Six Sigma Black Belt, accredited by ANAB.

How do I know if I qualify for RPL?

There’s no fixed public checklist — eligibility is assessed case by case based on your actual training and work experience. Contact Lean Six Sigma Australia with a summary of your background and they’ll confirm whether you qualify and which belt level it fast-tracks you to.
