About the ASQ CSSBB Exam

The ASQ Certified Six Sigma Black Belt (CSSBB) credential is designed for experienced professionals who lead improvement projects, apply the DMAIC methodology, analyze complex data, and guide cross-functional teams. The exam is broad and application-focused, requiring candidates to move between leadership, project management, Lean Six Sigma tools, statistical analysis, and practical decision-making.

The computer-based CSSBB exam contains 165 multiple-choice questions, including 150 scored questions and 15 unscored pretest questions. Candidates receive 4 hours and 18 minutes of exam time within a 4.5-hour appointment. The examination is open book, subject to ASQ’s rules for reference materials.

Applicants must also meet ASQ’s experience and project requirements. Candidates need either one completed Six Sigma project with a signed affidavit and three years of relevant work experience, or two completed projects with signed affidavits.
