General

What is the Lean Six Sigma Green Belt certification?

Who should take Green Belt training in St. Louis?

Green Belt training suits quality engineers, operations and production leads, continuous improvement specialists, analysts, and professionals moving toward Black Belt. In St. Louis it maps well to roles across healthcare, aerospace, manufacturing, and financial services employers that run active improvement programs.

Is the Green Belt worth it in St. Louis?

Yes. Process improvement managers in St. Louis average over USD 127,000 a year and continuous improvement managers higher still, and employers from BJC HealthCare to Boeing actively seek certified talent. The credential signals you can deliver measurable savings, which lifts both your pay and your prospects. Talk to a learning advisor to plan your path.

Do I need a Yellow Belt or prior experience first?

No. There are no formal prerequisites for the Green Belt, so you can start without a Yellow Belt or specific work experience. Training and hands-on practice are recommended, and our program is structured to support learners who are new to statistical methods.

How long is the Green Belt credential valid?

The credential is valid for three years from the date you certify. To keep current status, you pass a recertification exam before the three-year period elapses, which keeps your skills and credential up to date.

Pricing

What is included in the Green Belt training fee?

The training fee covers instructor-led or self-paced access, structured courseware aligned to the Green Belt Body of Knowledge, practice questions, mock exams, downloadable templates, learner support, and a course completion certificate. Request a quote to see what your chosen format includes.

How much does Green Belt training cost in St. Louis?

Pricing varies by format, schedule, and whether you train individually or as a team. Live online and classroom options are priced differently from corporate group programs. Contact us for current St. Louis pricing and a tailored quote for your needs.

Is the exam fee included in the course price?

The exam voucher is purchased separately and is billed in USD, with the base price varying by location and region. The training fee covers your preparation and courseware. We can guide you on buying and scheduling the exam voucher when you are ready.

Do you offer corporate or group pricing?

Yes. We offer corporate group training with customized schedules and volume-based pricing for operations, quality, and improvement teams. It is a cost-effective way to upskill several people at once. Ask about group rates for your St. Louis team.

What payment options are available?

We accept major credit and debit cards and bank transfers, with installment options on selected plans. Speak with a learning advisor to choose the payment approach that suits you or your organization.

Exam

What if I do not pass the Green Belt exam the first time?

You can retake the exam, and our training is built to get you ready the first time with mock exams, practice questions, and trainer support that target your weak areas. Selected plans also include retake support, so you can prepare with confidence.

What is the format of the Green Belt exam?

The IASSC Green Belt exam is closed book with 100 questions, using multiple-choice and true or false formats, and an allotted time of three hours. Some exam forms include up to 10 additional unscored questions. It is delivered online with proctoring or at a Pearson VUE test center.

What score do I need to pass the exam?

You need a minimum of 385 points out of 550 to pass. Questions are spread roughly evenly across the five DMAIC phases, so broad, balanced preparation across Define, Measure, Analyze, Improve, and Control is the best approach.

How and where do I take the exam?

You can sit the exam through secure online proctoring on demand, or in person at a Pearson VUE test center. Both options use the same closed-book format, so you can choose whichever is more convenient for your schedule and location.

Are there eligibility requirements to sit the exam?

No. There are no mandatory education, experience, or training requirements to take the Green Belt exam. Real-world experience and structured training are recommended because they improve your readiness, but they are not required to register.

Course Content

Can a beginner take this course?

Yes. The course is designed for learners who are new to Six Sigma, and trainers explain statistics, process mapping, and analysis tools in plain language. Hands-on exercises and practice problems build your confidence step by step throughout the program.

Are practice tests and mock exams included?

Yes. The program includes practice questions and full-length mock exams mapped to the Green Belt format, plus topic-wise quizzes. These help you find weak areas, build recall, and walk into the exam knowing what to expect.

Is the courseware aligned to the current Body of Knowledge?

Yes. The courseware is aligned to the IASSC Lean Six Sigma Green Belt Body of Knowledge, which is organized around the five DMAIC phases. This keeps your preparation matched to the structure and content the exam evaluates.

Will I receive a certificate of completion?

Yes. After meeting the course requirements you receive a course completion certificate from Invensis Learning. This recognizes the training hours you completed and is separate from the Green Belt credential, which you earn by passing the exam.

Enrollment

How soon can I start and how do I enroll?

You can enroll online through the Invensis Learning website by choosing your format and completing payment, after which you receive access to schedules and learning resources. New batches open regularly. See upcoming schedules or talk to an advisor to pick a start date that fits.

What training formats are available?

Can I reschedule to another batch?

Yes. Flexi options let you reschedule or transfer to another batch, and selected plans include a Flexi Pass to attend the training twice. Contact support and we will help you move to a session that works for you.

What is the refund or cancellation policy?
