Our verdict

Our verdict8.3/10

Lean Sigma Corporation positions itself as a Six Sigma certification authority, offering structured, standards-based courses and separate certification exams from Yellow Belt to Black Belt, with digital credentials and a public certification directory that employers can check.

It says it has issued credentials since 2010 and also serves universities and training partners. Pricing shared by the provider lists PMP exam prep at $995 and an option with coaching at $1,990, but the current site focuses on Six Sigma and we could not find those PMP pages or Six Sigma prices when we checked. Confirm the product and price before buying. It suits professionals who value a verifiable Six Sigma credential.

Best for: Professionals who want standards-based Six Sigma (Yellow to Black Belt) certification with a verifiable directory listing.

Lean Sigma Corporation’s current offer centers on Six Sigma training, standalone exams, and publicly verifiable credentials. Although this site places it in the PMP category, its PMP URL returns a page-not-found message. The Six Sigma courses are therefore the focus here; older partner information does not establish a current PMP product. Process-improvement learners may find it worth investigating once tuition and exact assessment requirements are confirmed.

Pros & cons

✓What we like
  • Yellow, Green and Black Belt courses and exams
  • Certified professionals listed in a public directory
  • Issuing Six Sigma credentials since 2010
  • Programs for universities and training partners
!Watch out for
  • Prices not visible on the pages we loaded
  • The PMP prep product in the partner listing was not found on the current site

What you’ll learn

The certification-course page distinguishes roles at several belt levels. Yellow Belt develops the terminology and understanding needed to participate in improvement work; Green Belt focuses on leading defined projects using DMAIC; Black Belt addresses more complex organizational improvements. Black Belt Plus is presented as an applied path involving validation by a Master Black Belt.

That role-based structure is more useful than selecting the highest belt by name alone. A participant supporting a project and a leader responsible for enterprise-wide improvement have different learning needs. The overview establishes those distinctions but does not publish enough detail to describe every statistical technique, software exercise, or project deliverable across all levels.

Format, schedule and time commitment

Structured online courses allow self-paced study, but the pages examined do not establish the duration or access limit for each belt. Yellow, Green, Black, and Black Belt Plus serve different levels of responsibility. Get the timetable for the level you intend to take rather than applying one course’s schedule across the range.

Applied assessment may also create a different planning burden from reviewing lessons or sitting an exam. Ask the provider what evidence is required at your chosen level and whether an existing workplace project is needed. The presence of project policies in the navigation does not by itself establish that every course has identical project requirements.

Accreditation and what the credential is worth

Lean Sigma Corporation issues its own digital credentials and lists certified professionals in an official directory. Public verification can help an employer confirm that the award was issued, which is a concrete feature beyond receiving an uncheckable completion document.

The site describes its work as standards-aligned and uses accreditation language, without establishing a named independent accreditor for every course on the pages examined. Lean Sigma Corporation’s awards should not be presented as PMI, ASQ, or another organization’s certification. Ask the employer requesting a belt whether it accepts this issuer, and check how course completion differs from passing the certification assessment.

Price, payment plans and refunds

The current Six Sigma pages examined did not establish course prices. Older partner quotes for PMP training and coaching are not used as tuition here because the corresponding PMP product could not be confirmed on the official site. Ask for pricing tied to a current belt course or examination.

Certification courses and certification examinations have separate entries in the official navigation. Decide first whether you need instruction plus assessment or an exam to validate prior knowledge. The overview does not say every course price includes all examinations, project reviews, or later attempts, so request an itemized quote.

Links to return, exam, and project-submission policies appear in the navigation, without their complete conditions on the overview. Request those policies with the quote, including the access period and any extra assessment charges. A discount or installment arrangement could not be verified, so neither is assumed to reduce the total here.

Who it’s best for — and who should skip it

This provider fits someone deliberately seeking a Six Sigma credential with an identifiable issuer and verification directory. Its institutional programs may also be relevant to an organization or university sourcing courseware, though that is a different purchase from individual enrollment.

Skip it as an assumed PMP preparation option unless the company provides a current, specific PMP listing. A project manager who needs PMI education hours should compare documented PMP courses instead. For Six Sigma, choose the belt associated with the responsibilities you intend to take on rather than assuming the most advanced title is automatically the best entry point.

Pros and cons in detail

  • A belt progression: Yellow, Green, and Black Belt courses and examinations are offered.
  • Public credential verification: Certified professionals appear in an official directory.
  • An established issuer: The company says it has issued Six Sigma credentials since 2010.
  • Institutional options: Programs also serve universities and training partners.
  • Tuition still unclear: Prices were not visible on the accessible course pages.
  • No current PMP product confirmed: The PMP preparation offer in older partner information was not found on the present site.

The belt progression gives the catalog a coherent structure, and separate exam paths may be useful to professionals who already have relevant learning. A credential directory makes issuance verifiable, while the stated history since 2010 and institutional offerings provide background on the organization.

Tuition remains unresolved, as does the mismatch between the current Six Sigma offering and this site’s PMP category. A directory confirms that an award exists; it cannot guarantee that every employer accepts the issuer. Likewise, institutional partnerships do not establish accreditation for an individual enrollment. Request the exact belt syllabus, assessment requirements, and itemized price together.

How it compares

Simplilearn PMP Certification Training is an actual PMP preparation option if that was your reason for finding this listing. A live cohort was shown at $699 instead of $999, with 35 instructor-led contact hours, an education-hours certificate, and lifetime self-paced e-learning access. Simplilearn identifies itself as a PMI Authorized Training Partner. These features address PMP preparation rather than an equivalent Six Sigma belt.

Brain Sensei PMP Exam Prep takes a self-paced, story-based approach with a simulator and 35 education hours. On October 5, 2026, its detailed page showed one-year access reduced from $499.99 to $299.99, plus monthly access with conflicting amounts of $99 on a tile and $99.99 in nearby text. Confirm the monthly price at checkout and use the selected package’s terms instead of older summaries of different access periods. This is another PMP route, not a replacement for Lean Sigma Corporation’s process-improvement certification.

The category mismatch prevents a useful belt-for-belt comparison with the other programs assigned here. These alternatives instead clarify the choice between PMP exam preparation and Six Sigma certification. Lean Sigma Corporation remains in this site’s existing category, but neither PMP provider should be understood as awarding its belts.

If you intended to study for PMP, continue with the PMP Certification Prep category. The review methodology explains our curriculum, credibility, value, flexibility, and support criteria, including the need to assess the product actually offered.

How to enroll

Open Certification Courses and select the belt matching the role described on the official page. If already trained, inspect Certification Exams separately rather than assuming another full course is required.

Before registration, request the price, included assessment, project requirements, access period, and return policy for that exact route. Check how the digital credential and directory listing are issued after successful assessment. Avoid using the unavailable PMP page or a historical partner quote as the basis for payment.
