Built so it stays.

Most Six Sigma training is a long deck and a quick test, and a month later it is gone. This is the other way: four belts on one ladder, lessons you can watch, hear or read, a quiz at the end of every module, a tutor that answers from the course, and a certificate anyone can check.

How learning works

Slides you can hear, and a tutor that has read them

From Yellow Belt up, every section is a run of HD slides with a voice, captions and a transcript. Quizzes check you kept up, and the question you would have asked a classmate goes to SigmaTutor, beside the slide.

  • HD slides with voiceover, captions and a transcript
  • Module quizzes that tell you whether you are ready to move on
  • Your place and progress kept in the section outline
  • Ask SigmaTutor from any lesson

Eight screens, seven agents

The agents a learner meets

Seven of the thirteen agents work on the learning side: they answer, explain, plan, test and keep you going. Each one is a screen in the product.

All thirteen agents

On film · 1:32

Watch the seven at work, one job each.

Studying alone is hard: nobody to ask, nobody to say what is next, no way to know if you are ready. The film shows each agent answering one of those, on its real screen.

SigmaTutor

Ask the course anything

A tutor that has read the course you are on. It answers from the module and section you are studying, and shows where the answer came from, so you can go back to the slide.

  • Grounded in your belt and your current section
  • SigmaHub finds the passage the answer comes from
  • Open from the dashboard or from any lesson

The exam

One bar, three attempts, no clock

Every belt ends in an online exam, graded on the server. The rules are the same at every level; the paper gets longer as the belts go up.

    the same bar at every belt

  • 3

  • Yellow Belt25 questions
  • Green Belt40 questions
  • Black Belt60 questions
Questions in one sitting

White and Yellow serve their full question set. Green and Black draw a fresh set from a larger bank each time, so a retake is a new paper rather than the same one again.

Questions

Before you enroll

The straight answers.

  • Is the White Belt really free?

    Yes. Create an account and the White Belt course opens: five modules, the exam, and the certificate if you pass. No card and no invitation.

  • Which certificates can I earn today?

    White and Yellow are earned by passing the exam. Green and Black also require a capstone project, reviewed at five tollgates. The certificate is issued once both the exam and the capstone are passed.

  • Is the exam timed?

    No. There is no clock. You need 70% to pass, and you get 3 attempts, 24 hours apart.

  • What is SigmaTutor, exactly?

    A tutor that has read the course you are on. It answers from the module and section you are studying and shows where the answer came from, rather than answering from memory.

  • How does an employer check my certificate?

    Every certificate has an ID and a QR code. Anyone can confirm it at sigmaforge.ai/verify, free and without an account.

  • We want to train a team, or teach a course. Who do we talk to?

    Us, directly. Team enrollment runs through the enterprise workspace, and universities get courses with join codes and a grading desk. Get in touch and we will set it up with you.
