CLSSYB Exam FAQs for 2026 Candidates
Which certification does the CLSSYB exam lead to?
The CLSSYB exam is the official GAQM (Global Association for Quality Management) exam behind the Certified Lean Six Sigma Yellow Belt certification, validating the skills measured by the GAQM Certified Lean Six Sigma Yellow Belt credential. It sits at the Entry / Yellow Belt level of the GAQM (Global Association for Quality Management) certification program. It also connects to CLSSGB (Green Belt), CLSSBB (Black Belt), CLSSMBB (Master Black Belt), CLSSC (Champion), so the knowledge you build here carries over to those tracks as well.
How many questions are on the CLSSYB exam, and how much time do I get?
The CLSSYB exam contains 50 questions to be completed within 60 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the Getcertkey test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

That simple habit is the cheapest exam strategy there is.
