Our verdict

GLSS suits Lean Six Sigma learners who want assessed training on a subscription and a trial before they pay. The free tier and the 14-day trial make entry cheap, but the money-back period of 0 days leaves little room after that, and renewal lands at $499.

Pros and cons

Pros

  • Entry sits at $0, and GLSS places 1 of 220 on price from.
  • The certificate fee is $0, and GLSS places 1 of 47 on certificate fee.
  • A free tier and a 14-day trial let a learner look at the material before paying.
  • A team plan is available, so several learners can be bought in together.

Cons

  • The money-back period of 0 days sits well under the 14-day median across the site, and GLSS places 155 of 159 on that measure.
  • A 14-day trial is brief next to the 28-day upper end on the site, so cautious buyers get a short look.
  • Support runs on email, chat and help centre, which leaves questions to email, chat or the help centre rather than a phone line.
  • Coverage is limited to business and it in English, so learners outside business improvement will find little on offer.

Who it suits

  • Learners who want to start at $0 and pick up a certificate with a $0 certificate fee.
  • People who prefer a defined 12-month window and assessed work rather than open ended access.
  • Teams buying seats together, since a team plan is available.

Who should look elsewhere

  • Readers who would rather see a listed entry fee than rely on a free tier may prefer DRCertifications, priced from $19.99.
  • Anyone weighing non-US pricing can compare Academy for Health and Fitness, a UK provider priced from £25.
  • Learners after a broad marketplace rather than one certification track should look at Hotmart, whose yearly price is $0.

Where it sits among rivals

GLSS looks strong on the headline price rows and weak on the guarantees. It places 1 of 220 on price from and 1 of 47 on certificate fee, the two measures readers in this group check first. The picture changes at renewal, where 67 of 78 on yearly price is a mid table result. The trial sits at 21 of 63, and the money-back period at 155 of 159, close to the floor of that table. Entry pricing is where GLSS wins, and the refund promise is where it gives ground.

Pricing

GLSS runs on a subscription basis, and the introductory price is $0. The subscription plan then renews at $499, and that renewal figure decides what a further term costs. The certificate fee is $0, so nothing is added on top for the certificate itself. The gap between the entry price and the renewal price is the main thing to weigh here, and it is a wide one.

What it does well

Assessments come with the training, which suits people who want tested progress rather than passive video watching. Access runs for 12 months, a fixed window that keeps study on a schedule rather than open ended. A team plan is available for managers buying seats together, and the free tier plus a 14-day trial let a learner sample the material before paying. The money-back period of 0 days is the weak spot in this section, since it leaves no second chance once a paid term begins.

Free plan and trial

There is a free tier, and the trial runs 14 days, so a learner can read the material before paying anything for a term. The weak edge is the money-back period, listed at 0 days, which leaves the trial as the only comfortable exit. Paying later means paying without a refund route behind it.

How GLSS compares

Frequently asked questions

What does the subscription cost?+

GLSS prices as a subscription, with entry at $0. The subscription plan renews at $499. The certificate fee is $0, so nothing is added for the certificate itself. Anyone planning to stay through several terms should budget against the renewal figure rather than the entry one.

Is there a free plan or a trial?+

There is a free tier, and the trial runs 14 days. That gives a learner a full look at the material before committing to a paid term. The money-back period is listed at 0 days, so the trial is the comfortable point at which to decide.

What do I get with the certificate?+

The certificate fee is $0, and certificates come in completion and professional forms. No separate purchase is needed for either. Questions about what a certificate covers can go through email, chat and help centre.

How long do I have to finish the training?+

Access lasts 12 months from the start of a term, which gives a defined window for working through the material. Assessments sit inside that window rather than being an optional extra. Anyone planning a slower study rhythm should check the window before starting.

Which subjects are covered?+

GLSS teaches business and it subjects, which keeps it inside the business improvement field rather than a general catalogue. Course material is delivered in English. Learners after a different discipline may find the range narrow.

Can a company buy seats for a team?+

A team plan is available, so a manager can buy places for several learners at once. That suits organisations training a group through the same material. Support for a group runs through email, chat and help centre, and assessments are part of the course for each learner.

Can I get a refund if the course is not for me?+

The money-back period is 0 days, which leaves no refund window to lean on once a paid term starts. That places GLSS at 155 of 159 on this site. The 14-day trial is the safer point to test the material.

How do I get help, and who runs the site?+

Help runs through email, chat and help centre, so questions can go by email, chat or the help centre. The operation sits in the US and is run by GLSS (GoLeanSixSigma.com). Support is written in English, matching the English the courses use.
